We independently change the rear springs on a VAZ 2107

Removing and installing the VAZ 2107 front suspension spring

Place the car on a lift or inspection ditch;
holding the end of the rod by the flats with a wrench A.57070, disconnect the upper end of the shock absorber and remove the front wheels. Having straightened the locking plates, unscrew the bolts securing the caliper to the bracket. Move the caliper to the side and secure it so that it does not hang on the hoses. Remove the shock absorbers with brackets.

Disconnect the ends of the anti-roll bar from the lower control arms.

Using puller 67.7801.9513, press the pins out of the holes in the levers and move the steering rods to the side.

↑ Spring compression with device 67.7828.9504

1 — suspension spring; 2 — screw of the device; 3 - support plate.

• Insert screw 2 of tool 67.7828.9504 into the hole in the upper support of the suspension spring.
• Then place the support plate 3 on the spring coil 1 and on the screw 2 from below and secure it to the spring with a clamp.
• Screw the nut onto the screw from below so that the nut retainer fits into the socket of plate 3.
• By turning screw 2 with a wrench, compress the suspension spring until the suspension arms are completely unloaded.
• Take out the axis of the upper arm and disconnect it from the body.
• Disconnect the lower control arm axle from the cross member and remove the suspension assembly from the vehicle.
• Remove the spring, smoothly unloading it, remove the device and repeat the operations for the other suspension unit.
• Remove the engine splash guard and stabilizer bar.

NOTE! When removing suspension components, it is necessary to note the number and location of the adjusting washers between the axis of the lower arm and the cross member, as well as the adjusting plates between the cross member and the body side members, so that when installing the units, put these washers and plates in their original place.

↑ Installation of cross member A.70526 to support the engine when removing the front suspension cross member.

Supporting the engine with a cross member A.70526 or a hoist, remove the cross member.

Install suspension components and parts in the reverse order of removal.

Install springs on the front and rear suspensions of the same group (group A is marked with yellow paint, and springs of group B are marked with green). In exceptional cases, it is allowed to install group A springs on the front suspension, and group B springs on the rear suspension.

The front suspension should only have springs with yellow markings on the outer surface of the coils.

↑ Sequence of tightening nuts and axles in rubber-metal joints

To prevent improper distribution of forces in rubber-metal joints, tightening the nuts and lever axles must be done in the following order:

• Place the car on a level surface and place the wheels parallel to the axis of the car;
• load the car with a load of 3136 N (320 kgf);
• under these conditions, use a torque wrench to tighten the nuts securing the axles of the upper and then the lower arms and the nuts securing the axle of the lower arm to the cross member.

Check and adjust the front wheel alignment angles.

How to replace rear springs on a VAZ 2107

Replacement of rear springs on cars of classic models, such as the VAZ 2107, is carried out in two cases: if one of them significantly subsides or in case of mechanical damage. You should definitely remember that both need to be changed at the same time, otherwise the car will lose stability on the road due to tilting to one side. Unlike the front ones, replacing the rear springs does not require special tools and can be done in 1-2 hours without much labor. In particular, to replace the front springs you need a set of special pullers.

Rear springs for the VAZ 2107 are available in two sizes:

• Type A – length exceeds 273 centimeters – red color;
• Type B – length less than or equal to 273 cm – green color.

To work you need to stock up on tools:

• Two keys for 19;
• Two keys for 10.

In addition, you need to purchase two springs and two spare sets of rubber stands. If it is necessary to change the springs, then the stands may be suitable for further use. However, it is better to change them too while the car is disassembled, so that you do not have to do the same work again later.

To remove the springs on a VAZ 2107, you need to unscrew all the parts that interfere with the free movement of the bridge in the vertical plane. First, using 10mm wrenches, you need to unscrew the brake fluid pressure regulator rod.

After this, in order to avoid damage to the brake pipes, you need to unscrew the bolt securing the brake pipe tee using a 10mm wrench.

Next, use two 19mm wrenches to unscrew the lower shock absorber mount on the side where replacement is planned.

After this, we jack up the rear of the car on the side where you planned to work, the bridge lowers and the part is released. We take out the part to be replaced along with the upper and lower rubber pads, and install a new one in its place.

You should pay attention to the presence of protrusions on the linings on both sides. On one side the end of the coil rests on the protrusion, on the other we rest:

• into the protrusion on the car body for the upper lining;
• into the protrusion on the bridge platform for the lower lining.

After installing the part in its normal place, remove the car from the jack and screw on the shock absorber. The replacement of one element is completed, you can move to the other side. Having replaced both springs, we assemble the brake system parts in the reverse order. At this point, the work of replacing the rear springs can be considered completed. For VAZ 2107 vehicles with a long service life, before unscrewing the nuts, it is recommended to treat them with a special penetrating lubricant such as WD-40 to make work easier.

When it's time to replace

There are several signs by which you can determine that it is time to replace the springs. These signs are:

• Detection of damage and defects in the product design. This malfunction can be determined by visual inspection, but first you need to put the VAZ 2107 car on an overpass.

Their significant subsidence. If the vehicle's ground clearance decreases significantly, this indicates sagging of the devices in question. Springs quickly sag in such cases when the car is used to transport heavy loads every day. Also, those cars that are used as taxis also require frequent replacement of the devices in question.

If you find a problem with the springs on a VAZ 2107, then you should replace them without delay. This will extend the life of other suspension elements and save money. It is recommended to replace devices in pairs, since replacing only one element will cause the body to skew, which will negatively affect driving. In some cases, spacers help when the springs have sagged but are not deformed. Experts believe that you should not get carried away with spacers, since the physical properties of a car with spacers are many times worse. As a result of such modifications, the suspension does not function correctly, which affects many factors: from control to comfort. Therefore, if necessary, it is better to replace the springs, both rear and front. We will learn how this is done on a VAZ 2107 from this material.

Replacing the front springs of a VAZ 2107

Replacing the front suspension elements on the “seven” is carried out according to the following scheme:

1. First, you need to install the car on an inspection hole or overpass, and then begin to remove the wheels, having first jacked them up.
2. The front shock absorber needs to be removed.
3. The nuts that secure the lower arm to the axle are loosened.
4. Using a second jack, you need to place it under this lever, thus adding the suspension load. This is done to make it easier to disconnect the stabilizer.
5. At this moment, you can use special spring ties (if available) to secure the springs in a compressed state. This will make further removal actions much easier.

The front springs of the VAZ 2107 need to be changed in pairs, just like the rear ones.

Changing the rear springs on a VAZ 2107

Replacing the rear springs of a VAZ 2107 is carried out according to the following principle:

1. Install the jack and remove the wheel.
2. The pressure regulator rod in the brake system is unscrewed.
3. The rear pipe tee bracket is unscrewed.
4. The shock absorber fastener at the bottom is unscrewed.
5. Jack up the car and thereby release the shock absorber and spring fasteners.
6. Now you can remove the spring, which also has a rubber spacer. If the spacers are deformed, they should be replaced.
7. Replace the removed springs with new ones, installing all the removed parts in the reverse order of removal. When installing products, it is important to purchase special ties, as shown in the photo below.

Replacing the rear springs is much easier and faster, so it will take half a day to replace all four products.

What springs to install

It remains to figure out the question of what springs to put on the VAZ 2107? Instead of standard products, you can install reinforced devices. The replacement principle is similar, but the result will be significant. The suspension with reinforced devices will become stiffer, but it is important to know that at the same time you will need to install new shock absorbers (more powerful).

Many car owners are wondering what springs are best to install on a VAZ 2107? The best option for a rear-wheel drive sedan is products marked 2101. They are quickly and easily installed in standard places and do not require modifications. When choosing products, you need to pay attention to their manufacturer. There are many manufacturers, both domestic and imported, but it is important to pay attention to the cost. When choosing, pay attention to the stiffness class of the springs, the number of turns and their thickness. There are two types of hardness:

1. Type A, whose length exceeds 273 cm. They are red in color and are the toughest.
2. Type B. Their length is up to 273 cm and their color is green. Such products have reduced rigidity.

In conclusion, it should be noted that the higher quality the product, the longer it will last. Therefore, when choosing, it is important to analyze for what purpose you need a car: to transport cargo or simply carry passengers.

Replacing the front suspension spring of a VAZ 2107

Today we will talk about replacing the front suspension spring of a VAZ 2107 with your own hands. The article will be accompanied by photographs and a detailed description of all actions.

According to the length under the normalized load, the front suspension springs of the VAZ 2107 are divided into two groups: A - “long”

and
B - “short”
. The front suspension springs of group A are marked with yellow paint, the front suspension springs of group B are marked with green paint.

The vehicle must have springs of the same group installed. The front suspension springs on a VAZ 2107 should be replaced in pairs if at least one of the springs shrinks, deforms or cracks.

To do the work of replacing the front suspension spring on a VAZ 2107 with your own hands, you will need ties to compress the springs.

Warning:

Use only reliable factory-made ties to compress the spring and strictly follow the instructions for their use. The suspension spring has great strength. The spring breaking off the ties can cause serious injury.

How to remove the front suspension springs of a VAZ 2107

1. First of all, you need to prepare the car for repair.

2. Remove the front wheel from the car.

3. Remove the shock absorber from the VAZ 2107.

4. Loosen the two nuts securing the lower front suspension arm to the axle.

5. Disconnect the stabilizer cushion clip and remove the cushion.

6. Press the lower ball joint pin out of the steering knuckle.

7. Install the jack under the lower arm without loading the front suspension of the VAZ 2107, and unscrew the nut securing the pin.

8. Carefully unload the suspension (by lowering the jack) and at the same time, using a mounting blade, move the stabilizer through the upper stud securing its bracket.

9. Remove the jack.

10. Using a mounting blade, pry the spring from below and remove it from the lower arm support cup.

11. Remove the spring and the insulating rubber gasket from the upper support cup.

Installing a front suspension spring on a VAZ 2107

1. Before installing the spring on the VAZ 2107, attach the upper rubber gasket to the spring with insulating tape, ensuring that the end of the screw surface of the gasket coincides with the end of the spring coil. We install two ties on the spring, without catching them on the last turns, and tighten the spring to a height of no more than 280 mm.

2. Install the front suspension spring on the lower arm support cup and orient the spring so that the end of the spring coincides with the screw surface of the lever support cup.

3. Place the jack under the lower arm and lift it, making sure that the rubber gasket is installed on the upper support cup.

4. Raise the lever with a jack and guide the pin of the lower ball joint into the hole in the steering knuckle.

5. Tighten the self-locking pin fastening nut 4-5 turns. We loosen the ties and remove them through the technological hole in the lower arm.

6. Raising the lever, press in the pin of the lower ball joint and tighten the self-locking nut.

7. Install the remaining parts in the reverse order of their removal.

8. Having installed the car on the wheels, we finally tighten the nuts securing the lower suspension arm to its axle and securing the stabilizer pad holder.

9. Similarly, we replace the second spring of the front suspension on the VAZ 2107 with our own hands.

Let us remind you that the previous article was about adjusting the front wheel bearing of a VAZ 2107 with your own hands.

Signs and malfunctions of the front springs of the VAZ 2107

To avoid unpleasant consequences, it is important to identify the problem in time. This is not difficult to do. During operation, you will notice that the car has “squatted” in height and the ground clearance has decreased.

If one of the springs fails, a slight roll may occur. If both springs are damaged, the car will visually “nod off”, that is, the front part will be significantly lower than the rear.

In addition, the malfunction can be identified by inspection - damage will be visible on the spring (cracks, traces of impacts against each other, and so on).

Many car enthusiasts install spacers under the springs and solve the problem this way. It is not right. In most cases, such products are ineffective.

In the best case, you can raise the ground clearance, but if there is a malfunction or defect, then the best solution is to replace the VAZ 2107 front suspension spring.

How to replace rear springs on a VAZ-2107

Over time, the elasticity of the metal decreases, the car sags, and in potholes the wheels begin to reach the wheel arch liners. It's time to replace the rear springs . The procedure is not complicated and a driver with minimal plumbing experience will be able to fix the problem on his own. This article is suitable for owners of all “classic” VAZs from 2101 to 2107 . Sometimes replacing the spring spacers with thicker ones helps. They are available in three versions with different thicknesses. If the springs haven’t burst, then the Zhiguli car is still ok with inflated spacers.

Helpful information

A short rod unscrewed from the stocking will facilitate dismantling and installation. For ease of assembly, a new rubber spacer and a metal lining are fixed to the spring with electrical tape or tape. Reinforced springs with VAZ 02 - 04 will increase the load capacity, but the car will become rougher to drive. It is easier to replace the torque rods with new ones without wasting time pressing the bushings in a vice. When experimenting with the height of the springs, you should remember the length of the shock absorber stroke. They may have to be lengthened or different ones used. During disassembly, the brake hose receives extra stress, which can lead to damage.

Follow safety precautions and replacing rear springs will not be a hassle.

Replacing suspension springs on a VAZ-2107

We carefully inspect the suspension springs. Sagging springs, as well as those with cracks and severe corrosion, are replaced.

Check the technical condition of the insulating gaskets and replace them if they are damaged.

Replacing front suspension springs

To remove the front springs, we use a special device consisting of two grips installed between the coils of the spring and a screw tie.

Install the device into the spring and remove it.

Press the lower ball joint out of the steering knuckle (see Replacing ball joints).

We move the hub on the upper ball joint to the side. Use a 22mm wrench to loosen the nuts on the lower arm axle. (See Replacing the rubber-to-metal joints of the lower control arms on a vehicle.)

After making sure that the coils of the spring are tightened securely, push the lower suspension arm down and remove the spring along with the device from the lower arm.

A rubber insulating gasket is installed on the top of the spring

Having compressed the spring three times until the coils touch, check its elastic characteristics at the control points.

Replace the damaged gasket with a new one. The length of a working spring in a free state should be equal to 360 mm. It is allowed to install identical springs on the front suspension only with yellow markings on the outer surface of the coils (group A).

Installation of springs is carried out in the reverse order of removal.

We install the car on the wheels, and then tighten the nuts of the lower control arm axles.

Replacing rear suspension springs

We disconnect the shock absorber from the rear axle beam bracket and...

We compress the spring with two special ties.

Instead of zip ties, you can use two or three strong staples, which are inserted from two opposite sides into a spring compressed by the weight of the car.

When hanging the wheel, they will not allow the spring to fully decompress.

A compressed spring is dangerous, so in addition to ties or staples, you can tie its coils with steel wire.

Using your hands, move the rear axle beam down and remove the spring.

A plastic gasket is placed under the lower part of the spring, and a rubber vibration-isolating gasket is installed on top.

We check the condition of the rubber gaskets and, if necessary, replace them with new ones.

Install the spring in the reverse order of removal.

We replace the second spring in the same way.

We install both springs of the same group (with markings on the outer surface of the coils with paint of the same color).

Class “A” springs (yellow) are installed on VAZ-2107 cars.

It is allowed to install springs of class “B” (green color).

In case of damage (cracks, peeling), replace the compression stroke buffer by moistening it with a soap solution before installation

Properties of suspension springs

When torsion bars on vehicles were replaced with springs, handling improved and suspensions became more convenient to maintain. Springs maintain the vehicle's ground clearance, reducing vibrations and shocks while the vehicle is moving.

To make the ride comfortable, you need to choose the right parts. If the technical characteristics are unsuitable, then the positive properties of the suspension will be reduced to zero. Therefore, it is important to consider the following parameters:

• diameter - its increase affects rigidity;
• number of turns - as the number increases, the rigidity decreases;
• form.

Often, car owners strive to install stiffer parts in the suspension. This helps to increase the sensitivity of the steering wheel to the driver's control, but the grip on the road deteriorates.

Fans of a sporty driving style believe that, on the contrary, it is better to install parts with reduced rigidity. However, this suspension can create problems on country roads.

Let's take a closer look at which springs are best installed on a VAZ.

Correspondence of spring markings to the model

When installing springs on a VAZ suspension, it is advisable to ensure their compliance.

• 2101 install on rear-wheel drive sedans.
• 21012 is tougher, made from a larger diameter rod. Installed on a VAZ with left-hand drive, with special equipment, when a front suspension with increased energy intensity is needed.
• 2102 are installed on station wagons VAZ-2102, 21014. Their length is increased by 21 mm compared to 2101, so they are installed on sedans only when you often have to drive on country roads so as not to hit bumps - when installing 2102, the ground clearance under body They cannot be used to increase the load capacity, since they inevitably lead to premature destruction of the body.
• 2108 is installed on all front-wheel drive models, except for modifications with a 16-valve engine and Oka. By the way, in the markets they often deceive owners of VAZ-21099 sedans by offering to purchase scarce “99 springs”. In fact, there are ordinary “eighths” there, and “99ths” do not exist at all.
• 2110 European ones are installed on the rear suspensions of VAZ 21102-21104, 2112, 2114, on the front and rear suspensions 21122 and 21124. The European version is created for cars intended for export. The ground clearance here is reduced by 20 mm, the compliance of the springs is reduced in order to increase their stability at high speed when turning. The cross-country ability of vehicles on off-road and dirt roads is significantly deteriorated.
• 2111 are installed on the rear suspensions of VAZ 2111 and 2113.
• 2112 are installed on the front suspensions of VAZ 21103, 2112, 21113.
• 2121 is used on all-wheel drive models, except Oka.

Choice depending on manufacturer

Often, when parts break down, drivers try to buy original factory parts as replacements, not wanting to experiment. However, there is a decent choice from other manufacturers, whose products are sometimes no worse than the original ones.

Sirius

There is a large assortment for different brands of cars, and parts are also manufactured in any configuration according to customer drawings.

Phobos

The quality is satisfactory, but, according to some car enthusiasts, after 2 years they begin to sag, losing rigidity. In total, about 500 types of springs are manufactured under this brand for any brand of car; there are standard, reinforced and lowered springs. Clearance kits with increased ground clearance are also available.

Technospring

Good quality for little money. They lose rigidity over time, but do not sag. Quite good as a budget option.

Koni

Very durable, no sagging. They have a stiffness adjustment directly on the car, done with a special thumb under the hood.

Eibach

High-quality, very durable, practically do not “age” - do not sag, do not lose rigidity. There is no roll when turning. But they cost one and a half times more than Koni.

SS20

Products of the SS20 brand undergo mandatory testing at test benches, after which they are selected in pairs with similar characteristics. This check ensures, according to the manufacturer, 100 percent product quality. A large assortment allows you to choose the right characteristics depending on your driving style and operating conditions. There are 3 options available:

• hot coiling of standard height with linear compression characteristic;
• cold coiling of standard height with linear and progressive compression characteristics;
• cold coils are lowered, with a progressive compression characteristic.

Kilen

Alternative original springs from Kilen are of the highest quality. The service life, as the manufacturers claim, is twice as long as the original VAZ products.

Asomi

Excellent springs made from special alloys, coated with epoxy coating to increase service life.

Installation Tips

1. Is it possible to install parts of different classes?

Remember that the springs on the suspension must be of the same class. Let’s say you installed A-class parts on the front suspension, which means you also need to install “A” class on the rear suspension.

• If a similar class is not available for the rear suspension, then in exceptional cases class “B” is assigned to the rear suspension.
• If B-class springs are installed on the front suspension, then class “A” springs cannot be installed on the rear suspension.
• Install suspensions of the same class on the left and right sides of the same axle.

1. What springs are better to install on a VAZ 2107?

Before changing parts, make sure that it is really necessary. You can check it in the following way: standing at the front of the VAZ 2107, swing the body down. If it quickly rises to its original position, there is no need to replace the springs; they are in good condition. If the body does not rise and continues to sway, then replacement is necessary. In the same way you can check the rear suspension of the VAZ 2107.

To improve the aerodynamics of the VAZ 2107 and improve the sensitivity of the steering wheel, it is recommended to install stiffer springs than the original ones. You can buy those designed for VAZ 2104, cut off one turn. It is imperative that on a VAZ 2107 you need to change two at the same time, otherwise the car will lose stability on the roads.

It is not recommended to install reinforced rubber gaskets on 2107, because the spring will break through.

1. Will Niva springs fit on a VAZ 2107?

If you want to make a sports tuning on the VAZ-2107, the suspension is made more rigid, this improves the quality of handling without reducing the level of comfort.

The rear springs are stiffer than the front ones. The factory ones are too soft, and the car quickly loses control, the bottom gets scratched on the road surface. To increase the stiffness of the suspension, it is recommended to install Niva springs on the VAZ 2107.

1. What springs are better to install on a VAZ 2110?

On the VAZ 2110, the front spring often breaks due to poor quality roads, so it needs to be replaced. Moreover, you can do this yourself, without contacting a car service. All that remains is to find out what is best to choose from the range offered for the 2110.

On the front suspension of the VAZ-2110, as standard, 2108 springs are installed, on the rear suspension - 2110. In the absence of original parts, car enthusiasts are advised to install SS20 highway, the car rides smoothly and is stable when cornering.

1. What springs are best to put on a Priora?

If the springs on the Priora have sagged, it is recommended to install new original ones from VAZ. Choose only the class depending on the goals of your tuning. Class "A" is more stringent. In the absence of the original one, according to car enthusiasts, it is better to install a kit with a lowering Eibach Pro-Kit (-30 mm).

1. What springs are better to install on a VAZ 2114?

The VAZ 2114 suspension is quite durable, and the need to replace parts occurs quite rarely. Therefore, not all car owners of 2114 cars know what is best to choose from the wide range offered on the markets.

Sometimes springs from 2112 are installed on a VAZ 2114, they are a little stiffer, designed for a larger weight of the car, so they raise the 2112 slightly - by 2-3 cm, which means that in this way you can increase cross-country ability. If, on the contrary, there is a desire to lower the car, then it is recommended to purchase an Eibach, with the front ones being -5 and the rear ones -7, so that the car does not ride up.

So, the choice of springs for VAZ is quite wide, the main thing is to choose the correct stiffness characteristics according to the load on the car and operating conditions. You will find a variety of advice on forums and blogs.

Of course, it is better to first consult with specialists.

Refusal of original parts in favor of other manufacturers may be dictated by the desire to improve the driving performance of the car, but be sure to compare the cost of tuning and the result obtained.

How to replace rear springs on a VAZ 2101 - 2107

183 6 175k

76 1 90k

A sure sign of the need to replace the rear springs on a VAZ Classic (2107, 2106, 2105, 2104, 2101) is sagging of the rear part of the body. Moreover, ground clearance is significantly reduced even at minimal loads.

Let us visually analyze the entire process of installing standard springs with medium spacers. You can also experiment a little and install springs with high spacers, but this is allowed if you install simple springs from 2101, their article number 21010-2912712-01, and not reinforced springs from 2102, article number 2102-2912712. What are the best springs to install on VAZ cars is described here.

Springs from 2102 are much higher than standard ones; if they are used in combination with high or medium spacers, they will most likely lift the car very much. Consequently, the travel of standard VAZ shock absorbers is not enough, which means you will also have to change the shock absorbers to longer ones, for example Moskvich ones. Part number: 402-2915006-A. Additionally, it will be necessary to carry out welding work to weld additional rings onto the shock absorber itself. But replacing conventional springs with cargo springs is necessary in cases where you load your Zhiguli every day.

The tools we need to carry out the work:

• two jacks, for example, “trapezoid” and “frog”;
• large screwdriver;
• two keys for 19;
• balloon wrench.
