Checking the condition and replacing jet rods of the VAZ 2107 (Video)

The use of reaction rods in the car suspension improves the stability and controllability of the car when driving, especially on uneven roads.
While driving, the rear axle experiences heavy loads with different directional vectors. Without reaction rods or with damaged rods, a car begins to behave dangerously under heavy loads on the suspension. It is the reaction rods that prevent the car from swaying and prevent it from tipping over during a sharp maneuver. Their condition critically affects driving safety. Therefore, you should periodically monitor the condition of the jet rods and carry out timely repairs or replacement of these parts.

Tie rod malfunctions

The jet thrust of the VAZ 2107, like any other car, takes on loads aimed at shifting or rocking the rear axle. If these parts fail, the car’s behavior on the road changes: handling deteriorates, braking distance increases, and even there is a threat of a sudden change in trajectory or the car overturning. What factors cause breakage or wear of steering rods?

Static loads. It is impossible to avoid this factor, but you can reduce it without overloading the car.
Torsional loads. They most often occur when hitting an obstacle. You can reduce them by reducing speed in front of an obstacle.
Chemical effects of water and chemicals sprinkled on roads in winter.

Therefore, it is important to regularly check the condition of the rods and promptly detect deformation, chips and cracks. The appearance of such signs indicates the need to replace the part.

The rear links of the VAZ 2107 have weak points - welding seams that attach the eyes to the link and silent blocks. The latter are made of rubber, which wears out much faster than metal rod parts. Wear of silent blocks contributes to the appearance of backlashes that prevent the rods from performing their stabilizing function. As for the breakdown of a welded joint, it can lead to the most disastrous results, even an accident.

A failure of the torque rods manifests itself in a characteristic knocking sound in the rear suspension while driving. Such a knock indicates the need to immediately check the condition of the rear suspension.

To eliminate defects in steering rods, as well as to diagnose the suspension, you can contact a service station. But you should know that repairing and replacing these parts is a fairly simple operation that you can do yourself, even without much experience in auto repair work.

About modernization of jet thrusts

Sometimes drivers decide to independently increase the reliability of the VAZ 2107 suspension and extend its service life. To this end, they are modernizing jet thrust. Typically, modernization of rods means two operations. Here they are:

installation of dual jet rods;
installation of reinforced jet thrusts.

Now a little more about each of the above operations.

Twin rods

Most often, drivers install dual rods on the VAZ 2107. The reason is obvious: for this procedure you don't have to do anything with the pulls. You simply purchase not one, but two sets of rods that are installed in a regular place near the rear axle of the “seven”. Plus, you purchase not ordinary, but elongated mounting bolts, on which this entire structure rests.

Installing double rods on the VAZ 2107 increases the overall reliability of the suspension

The obvious advantage of such modernization is the increase in the reliability of the suspension: even if one of the tie rods breaks while driving, the car is unlikely to lose control and the driver will always have a chance to notice the problem in time and stop (a break in the tie rod is almost always accompanied by a strong knock on the bottom of the car, which cannot be heard this is simply impossible). This design also has a drawback: the suspension becomes stiffer. If earlier it “eaten up” small unevenness in the road without any problems, now the driver will feel even small pebbles and holes while driving.

Reinforced traction

If the car is used in extreme conditions and drives mainly on dirt roads or on roads with very poor asphalt, the car owner can install enhanced torque rods on it. As a rule, drivers make such rods themselves. But recently, large manufacturers have begun to offer reinforced rods of their own production. For example, you can find Trek-Sport rods on sale, which are distinguished by the large size of silent blocks and an adjustable transverse rod. A pair of nuts on the crossbar allows you to slightly change its length. Which in turn affects the car’s handling and the overall stiffness of its suspension.

The reinforced rods have nuts that allow you to change the length of the rod and adjust the stiffness of the suspension

Of course, the driver will have to pay for increased reliability: the cost of a set of Track-Sport rods starts from 2,600 rubles.

Removing jet rods

Replacing jet rods on a VAZ 2107 consists of two stages: removing the old ones and installing new ones. The rods are removed as follows:

Thoroughly clean the threaded connections with a wire brush to remove any rust or dirt, then apply WD-40 and wait a while before continuing.
Unscrew the nut that holds the rod on the free side. It is quite difficult to unscrew, so you should take a wrench with a long handle and, if necessary, spray the threads again with WD-40.
Remove the bolt and nut and move to the other side of the rod.
Unscrew the nut of the lower shock absorber mounting and remove the bolt with the spacer sleeve.
Move the shock absorber to the side to gain access to the second linkage bolt.
Use a wire brush to clean the bolt threads and treat them with WD-40.
Unscrew the nut and remove the bolt.

Note: if the nut cannot be unscrewed, the bolt must be cut off.

Using a spudger, remove the torque rod.
If the bolt has been cut, remove the remaining linkage fastenings.

Note: it is unacceptable to try to weld cracks on a cracked rod - the seam will not withstand the load. Therefore, cracked rods must be replaced.

Purpose of thrust rods on the VAZ 2107

Tie rods provide protection against swaying and loss of control on the road, during sharp turns and obstacles. Even earlier versions of the car had similar problems. But inside the cars there were only ordinary springs; no one knew anything about the system with rods.

It is for this reason that the vehicle caused many problems when driving. Only over time the suspension was modified. A system was installed with several long rods. This part carried the main load.

Classic VAZ 2107 cars and other models contain the following version of the torque rod kit:

Long.
Short.
A large transverse one, which also serves as the basis for the entire system.

Installation location - near the car axle located at the rear. The system is visible only from the inspection hole, where repair work is usually carried out if the reaction rods are replaced.

Repair and installation of jet rods

If the metal part of the rod is in good condition, they can be reused. It is only necessary to replace the rubber silent blocks. To do this, you need to remove the old parts from the eyes and press in new ones. You can make pressing easier by lubricating the surface with dishwashing detergent (it does not corrode the rubber).

Installation of new rods is carried out as follows:

install the linkage eye in the front bracket;
lubricate the fastening bolt with nigrol or lithol, insert into the bracket and tighten with a nut;
install the rear bracket traction eye;
insert the fastening bolt, lubricated with nigrol or lithol, and tighten the nut.

Due to the displacement of the rear axle, the holes in the bracket and the linkage eye may not align. In this case, it is necessary to correct the position of the rod using a mounting blade.

After installing the links, you need to secure the lower part of the rear shock absorber.

Checking the condition of the jet rods on the VAZ 2107

100 thousand kilometers - new parts from the car are enough for this period, according to existing instructions. But the actual service life rarely exceeds 80 thousand kilometers, given real conditions.

The same instructions say that it is recommended to organize checks every 20 thousand kilometers. And here the experts recommend reducing the period by 5-10 thousand km to make it easier to avoid unpleasant surprises. You can’t do without an inspection hole and a mounting blade; this is the only way the jet thrust can be opened for viewing and other actions.

Test sequence

The steps are not that complicated:

Installation of transport on a viewing hole or on an overpass;
Mounting blades are inserted behind the traction eyes;
The spatula rests against the jet thrust bracket. An attempt is made to shift the part, together with the silent block. If the action is successful, it means the part is worn out and needs to be replaced;
Repeating a similar procedure with each silent block. If it moves sideways by a few mm, the need for replacement is obvious.

The rods themselves, along with the eyes, are also checked for wear. If any defects are detected, in this case the bushings and other parts are replaced.

Replacing steering rods VAZ 2107

Depending on the number of tips and rods to be replaced, you should decide whether to buy and replace parts separately or replace the steering linkage assembly. The assembled VAZ 2107 trapezium is easier to install and costs less than purchasing parts separately.

The work must be carried out by lifting the machine on a lift or placing it on an inspection hole. The thrusts on the left and right sides change approximately equally. The replacement procedure is as follows:

Note: if you do not have a puller, you can knock the pin out of the steering knuckle with a hammer by striking the lever along the axis. You can make the job easier by applying WD-40 to your finger. With its help, the finger will come out of the lever much easier.

Unscrew and unscrew the nut of the second finger of the tip.
Using a puller or hammer, press the second pin out of the intermediate joint.
Remove the steering rod.
Install a new rod.
Tighten and cotter the nuts on the rod pins.

This is how the steering rods of a VAZ 2107 are replaced. When replacing the trapezoid assembly, it is enough to disconnect the rods from the steering knuckles of the wheels and the steering gear lever, which will take less time and require less effort.

The steering ends are attached to the rods through special bushings that allow you to adjust their length. This sets the toe angle of the front wheels. When replacing steering rods or trapezoids, this angle will certainly be disrupted. When installing new rods and ends, care must be taken to ensure that their length matches the old ones. To do this, it is necessary to measure their parameters before dismantling. This will allow you to minimize the violation of the wheel toe angle and safely get to the service station, where specialists using special equipment will carry out a thorough adjustment.

Greetings, dear car owners. I suggest you watch a video instruction on the topic of Replacing jet rods of a VAZ 2107. Read carefully the instructions for the video.

Instructions: Replacing jet rods on a VAZ 2107 The weakest thing about jet rods is, of course, the rubber bushings. Replacing VAZ torque rod bushings as a step in the procedure Replacing jet rods. You can see how to cope with this task in the video on a specific example of a VAZ 2107 car. To change the rods or their bushings, you will need an inspection hole and a set of keys. The procedure itself is quite common. There is no need to jack up the car, but only have open access under the car. On all classics, whether on a VAZ 2107 or a VAZ 2101 or 2106, replacement of jet rods occurs in the same way. You will need to immediately unscrew the lower shock absorber mount, and then unscrew the rod securing bolts. After it is dismantled, you can begin either replacing the bushing or replacing the jet thrust completely, everything depends on the situation. Good luck on the roads and all the best.

Installation

If a grinder was used, it is important to remove all remnants of fasteners with a mounting spatula. How do you then replace the VAZ-2107 jet rods? After this, the new element is installed in the previous mounting locations. But installation may be difficult. Since the old rod could no longer cope with its task, the bridge could “move” a few degrees to the side.

To ensure that the new link is properly secured, rest the mounting blade against the bracket and unscrew the bridge until the holes line up. Next, tighten all the bolts and nuts. The same procedure is performed on the second side. For tightening, use the same wrench and a 19mm hex head.

How to change jet rods on a VAZ 2107 with your own hands

If the car remains stable while driving, it will be safe. This rule is equally relevant for passenger cars and trucks. The VAZ 2107 was no exception. The car could never boast of high handling. That's why engineers developed a system with jet thrusts. But even such elements can fail, raising questions about independent replacement.

Purpose of thrust rods on the VAZ 2107

It is for this reason that the vehicle caused many problems when driving. Only over time the suspension was modified. A system was installed with several long rods. This part carried the main load.

Classic VAZ 2107 cars and other models contain the following version of the torque rod kit:

Long.
Short.
A large transverse one, which also serves as the basis for the entire system.

Installation location - near the car axle located at the rear. The system is visible only from the inspection hole, where repair work is usually carried out if the reaction rods are replaced.

Jet thrust malfunctions and possible consequences

If the load causes the axle to sway or shift, the impact will be taken by the jet thrust. The appearance of defects in parts leads to a deterioration in the overall behavior of transport. Damaged parts need to be replaced as quickly as possible.

The following factors often cause breakdowns:

Exposure to chemicals from road compounds in winter;
Impact of torsional loads. Occurs more often when colliding with obstacles. Only reducing the speed before these elements reduces the risks;
Static loads. This factor is only reduced by the absence of overloads; it is impossible to completely get rid of it when operating rods on a VAZ 2107.

It is important to detect deformation, chips and cracks in a timely manner, for which periodic inspection of the entire system is organized. Welding seams and silent blocks are weak points that receive the most attention during inspections.

Silent blocks of any type are rubber, so they wear out faster than metal parts. Due to their wear, backlashes appear, becoming an obstacle to the stabilizing function. Welded joints, when they break, also lead to unpleasant consequences. It is recommended to remove them as quickly as possible.

With broken parts, driving is worse. Added to this is the unstable behavior of the body when defects appear in the jet rods.

Selection of thrust rods

The parts come from different manufacturers, the prices of which often differ several times. Production involves the use of spring steel as a base. Even when purchasing, it is easy to identify the presence of a defect in one case or another. It is necessary to inspect the part, especially in the welding areas. If there are chips and cracks, it is recommended to refuse the purchase. The fastening must not be damaged.

It is better to contact representatives of trusted stores. The main thing is not to forget to take a receipt, which simplifies the procedure for processing a return if necessary.

Replacing jet rods on a VAZ 2107

It is necessary to prepare a kit with tools and consumables in advance. Their main list is as follows:

Hammer;
Set with open-end wrenches. The reinforced double type parts are sometimes difficult to remove without additional tools;
Blades for installation;
WD-40 – this composition removes rust;
A set with new reaction rods, including a transverse one.

When everything is ready, they begin the work itself.

Removing jet rods

Removing old parts is the first step where work begins.

The process involves the following sequence:

A wire brush is used to remove rust and dirt from threaded connections. Then WD-40 is used for processing. You will need to wait some time before the work can continue. The instructions are also relevant for the classic model.
Completely unscrew the nut, due to which the washer is held on the free side. This process is difficult, it is better to take a long wrench and, if necessary, re-treat the surface with WD-40.
Dismantling the bolt and nut, moving to the other side. The rear parts are dismantled in almost the same way.
Unscrewing the nut from the lower shock absorber mounting. The bolt with the spacer sleeve is also removed.
Shift towards the shock absorber itself. Otherwise you won't be able to access the second bolt.
Clean the bolt threads with a wire brush, then apply WD-40 again.
Unscrew the nut and pull out the bolt. The elastic band also changes if necessary.

The bolt is simply cut off if the nut cannot be unscrewed. Removing the reaction rods involves using a spatula for installation. Remains of the fastening must be removed if the bolt had to be cut off.

Reverse welding of cracks will not help when they appear on the surface. The seam then still cannot withstand the load. Such parts can only be replaced in full.

Repair and installation of jet rods

Reuse is permissible only if the metal part remains intact. Rubber silent blocks must be replaced in any case. The old parts are removed from the lugs and then new ones are installed. Treating the surface with dishwashing detergent simplifies this process.
