The front wheel bearing on the Priora VAZ 2170, as on other VAZ cars, often fails, especially when the mileage exceeds 80,000 km. First there is noise from the wheel, which can increase during acceleration. Vibration also often occurs, wheel play increases, and in some cases the noise turns into a grinding sound - all these signs mean that the front wheel bearing of the Lada Priora requires immediate replacement. If you delay repairs, the consequences can lead to wheel jamming, which leads to unsafe situations on the road.
This article will tell in detail about the principles of replacing wheel ball bearings (hereinafter referred to as SP) on cars of the VAZ family, in particular on the Lada Priora. The instructions are accompanied by many photos and videos. The material also provides information on how to choose a front wheel bearing for a Priora by number, size, price, and manufacturer.
After reading the article, you will understand that replacing the front wheel bearing is done with your own hands without special skills, experience, or special tools, and the price for repair work of this type in a car repair shop is very high.
How to diagnose the front wheel bearing on a Priora and the causes of failure
At the beginning of the article, signs of a malfunction were already mentioned, if they occur in the VAZ 2170, it is necessary to check the hub assembly. To diagnose a breakdown, it is enough to do several operations:
- Raise the car with a jack;
- Check the play of the suspended wheel with your hands;
- Rotate the wheel and listen for noise;
- Watch several videos on the principle of diagnosing the front wheel bearing of a Priora.
Why does the front wheel bearing of a VAZ 2170 (Priora) fail:
- Expiration of service life;
- Incorrect operation of the suspension, aggressive driving style, road quality;
- Poor quality ball bearing (defect, counterfeit, manufacturing defect);
- Depressurization (dust, moisture, dirt);
- Malfunction of adjacent components (brake disc imbalance, etc.);
- Road accidents, collisions with deep potholes in the asphalt or holes.
Replacing the front wheel bearing on a Priora
To replace the front wheel bearing with your own hands and in garage conditions, motorists are more often inclined to use a method that does not require further wheel alignment, as well as specialized pullers.
To replace the front wheel bearing you will need:
- set of keys, sockets;
- round nose pliers;
- hammer, vice;
- screwdriver;
- jack;
- torque wrench;
- cup and three-jaw puller (if possible).
How to remove the front wheel bearing from a Priora
Removing the front wheel bearing of a VAZ 2170 and further replacement begins with placing the car on a flat surface, as well as ensuring sufficient illumination of the repair work site.
- Next we remove the brake caliper. First, unscrew the nuts on both sides to remove the housing itself.
- Now we remove the pads. Then unscrew the rear bolts with a 17mm wrench to remove the caliper from the disc.
- Unscrew the hub nut, then remove the brake disc.
- Now you need to press the hub off the drive shaft. Below is a method using a three-claw removable device.
- Next, unscrew the fastening nut to dismantle the casing.
- We unscrew the two nuts on the ball joint and use a 17mm wrench.
- Then we unscrew the two bolted connections that secure the pivot pin to the rack.
- Having disconnected the steering knuckle, we proceed to removing the ball bearing.
- We clamp the assembly in a vice so that the hub is at the bottom. Now we take the mandrel (in this case the head is 32 mm). By hitting the small bearing ring with a hammer, we knock out the hub through the frame, on which the inner race will remain.
- Remove the retaining ring using round pliers. Now you should press the outer race out of the steering knuckle. The photo shows a method using mandrels with a vice. The force from compressing the vice must be transferred to the outer race.
- Other methods: use a cup puller or tap with a chisel and hammer through a mandrel.
- Let's go back to the hub. At the hub, on the pressed-in old ring, we make a notch with a grinder.
- Then we knock down or split the clip with a chisel.
How to change the bearing on the front hub of a Priora
Before replacing the front wheel bearing, you should remove dirt and corrosion from the inner surface of the knuckle, as well as from the hub. The parts are wiped with a rag, and the seating surfaces are lubricated with machine oil. Replacement is carried out according to step-by-step instructions.
- We insert the new rolling element into the mounting hole, then hammer it through a wooden spacer evenly, without distortions, to a depth of 3-5 mm.
- Don't forget to put a retaining ring on the arc side.
- We press the ball bearing through a vice with a mandrel (or a piece of pipe), as shown below. Here you can also use a removable cup-type device.
- Insert the second locking element.
- Now you need to press the hub into the ball bearing hole. It is recommended to use the same mandrels.
- The assembled unit is mounted back onto the rack and ball joint. Then the locknut is tightened with a torque wrench (for tightening torque, see the table below).
- Further assembly is carried out in reverse order. We recommend watching the video of replacing the front wheel bearing on a Priora at the end of this article.
Replacing the front wheel hub bearing
There are two ways to replace a bearing. The first is by removing the steering knuckle assembly, the second is without removing it from the car. The work is shown on the right wheel bearing. The left wheel hub bearing is replaced in the same way. We remove the wheel.
Using a screwdriver, remove the protective cap from the hub. We install the wheel and tighten the two bolts that secure it. We lower the car onto its wheels.
Use a bevel to straighten the dented collar of the hub bearing nut in two places. Apply the parking brake, engage first gear and place shoes under the wheels.
Use a 30mm socket to loosen the hub bearing nut. The nut is tightened with a large torque, so the head and driver must be strong enough to transmit the necessary force. We hang up the front part of the car (namely both front wheels, because otherwise the anti-roll bar interferes with dismantling, pushing the suspension elements up). We remove the wheel. Unscrew the hub bearing nut completely...
...and remove the puck. Remove the front wheel brake disc (see “Removing the front wheel brake disc”). Disconnect the right wheel drive from the hub (see “Removing the front wheel drives”). In order not to disturb the wheel alignment angles, you can replace the bearing without removing the steering knuckle. To do this, connect the ball joint to the knuckle...
...and compress the hub by striking it through a soft metal drift. You can also compress the hub using the front wheel brake disc.
We pass M12 × 1.25 mm bolts about 130 mm long through two diametrically opposite holes in the disk and screw them into the holes of the hub to a depth equal to its thickness. By sharply hitting the bolt heads with a disk, we compress the hub. Then use a cup puller to press the bearing out of the knuckle, as shown below. If it was not possible to remove the hub in this way, remove the steering knuckle. To do this, unscrew the nuts of the bolts securing the shock absorber strut to the steering knuckle, remove the bolts (see “Removing the shock absorber strut and disassembling it”) and remove the steering knuckle.
We install the steering knuckle on the jaws of the vice and press the hub out of the knuckle through a mandrel or head of a suitable diameter, applying force to the end of the hub.
We remove the hub from the fist. In this case, the outer part of the inner ring of the bearing remains on the hub.
Remove the mud ring from the hub.
We insert a blunt chisel between the ends of the inner ring of the bearing and the hub and, striking the chisel with a hammer, move the inner ring.
Use a puller to compress the inner ring of the bearing.
Using circlip pliers, remove the circlip.
Use a cup puller to press the bearing out of the steering knuckle...
...and take it out with the puller.
Remove the bearing from the puller. Clean and lubricate the inner surface of the steering knuckle. Using a needle file, we clean out the nicks from the chisel on the hub. We press the new bearing into the steering knuckle, applying force to the outer ring of the bearing. We install a retaining ring in the groove of the steering knuckle socket. When pressing the hub, we use the puller washer to rest on the inner ring of the bearing. We carry out further assembly in the reverse order, tighten the bearing nut to the prescribed torque (see “Appendices”) and be sure to lock it by jamming the collar. If the bearing was replaced with the steering knuckle removed, then it is necessary to check and adjust the wheel alignment angles at a service station.
The front wheel bearing on the Priora VAZ 2170, as on other VAZ cars, often fails, especially when the mileage exceeds 80,000 km. First there is noise from the wheel, which can increase during acceleration.
Vibration also often occurs, wheel play increases, and in some cases the noise turns into a grinding sound - all these signs mean that the front wheel bearing of the Lada Priora requires immediate replacement. If you delay repairs, the consequences can lead to wheel jamming, which leads to unsafe situations on the road.
This article will tell in detail about the principles of replacing wheel ball bearings (hereinafter referred to as SP) on cars of the VAZ family, in particular on the Lada Priora. The instructions are accompanied by many photos and videos. The material also provides information on how to choose a front wheel bearing for a Priora by number, size, price, and manufacturer.
What front wheel bearing is in Priora: dimensions, number, prices, characteristics
Before you begin the repair, you need to know which front wheel bearing is on the Priora, as well as which one is better in terms of price, reviews, quality, and manufacturer. The designer at the manufacturing plant included in the design an angular contact double-row sealed ball bearing with lubricant inside (LITOL-24). According to reviews and statements from VAZ owners, the best option would be original products from VBF or foreign manufacturers: SKF, SNR, SWAG, FAG.
The dimensions of the front wheel bearing, as well as the catalog numbers of recommended manufacturers, are presented in the tables in a similar article on replacing the wheel bearing in a Lada Granta car; look for detailed information there.
