Attention! If, when swinging a suspended wheel, there is play or noise during movement, there is a possibility that the hub bearing has failed.
Attention! The hub has a double-row ball bearing that does not require adjustment or lubrication during operation. When pressing out the hub, the bearing is destroyed. Therefore, press out the hub from the steering knuckle only to replace the bearing.
Recommendation. If there is increased play in the wheel, loosen the hub nut and check its tightening torque. If the fastening is loose, try tightening the nut to the required torque and lock it. If there is no play, the bearing will be able to work for some time.
Set of mandrels for pressing bearings
To press in the hub bearing, use the appropriate size mandrels from the kit. If mandrels are not available, you can use the rings from the old bearing.
1. Remove the wheel and the hub nut cover.
2. Reinstall the wheel and loosen the hub nut.
3. Loosen the hub nut. It is tightened with a high torque, so it is recommended to use an extension, such as a piece of pipe.
4. Remove the front wheel, brake pads and caliper by hanging it with a rope or wire from the front suspension spring (see subsection 7.1.1.).
5. Remove the brake disc (see subsection 7.1.3.).
6. Press the ball joint pin out of the steering arm (see subsection 6.4.) and move the steering rod to the side.
7. Mark the position of the adjusting bolt head on the strut bracket. This will help you maintain approximately the same camber when installing the strut.
8. Loosen the nuts on the bolts that secure the steering knuckle to the strut.
9. Remove the two bolts securing the ball joint to the steering knuckle (flat and spring washers are installed under the bolt heads).
10. Finally, loosen the two nuts securing the steering knuckle to the strut and remove the bolts.
11. Completely loosen the hub nut.
12. Remove the thrust washer.
13. Remove the steering knuckle from the strut bracket and...
14....remove it together with the hub from the outer CV joint tailpiece.
15. Clamp the steering knuckle in a vice and press it out using a suitable punch...
16....the hub from the steering knuckle.
17. If the outer part of the inner bearing ring remains on the hub, press it off with a puller. For ease of dismantling, there are two special recesses on the hub.
18. If the outer mudguard needs to be replaced, use a drift to knock it off the steering knuckle (to replace the bearing you don't have to do this).
19. Using a screwdriver, carefully pry off the inner mudguard ring.
20. Remove the snap rings from both sides of the steering knuckle.
21. Having installed the device with the appropriate mandrel, press the bearing out of the knuckle.
22. Clean the hub from dirt and...
23....steering knuckle.
24. Use a hammer to knock out the damaged wheel studs and press in new ones.
25. When replacing a steering knuckle, remove the steering arm from it by unscrewing the mounting bolt and install the arm on the new knuckle.
26. Install the outer snap ring into the groove of the steering knuckle.
27. Press the new bearing into the steering knuckle using a suitable mandrel, applying force only to the outer bearing race on the inside of the knuckle. Do not hammer the bearing, as this may destroy it.

28. Install the inner snap ring.
29. Press in the inner mudguard ring using the tool cup.
30. Press in the outer mudguard ring using a suitable mandrel.
31. Install the hub and fixture with the appropriate mandrel into the steering knuckle (to apply force to the inner ring of the bearing) and...
32....press the hub into the inner bearing race.
33. Install the steering knuckle in the reverse order of removal. In doing so, turn the adjusting bolt so that the previously made marks coincide, and, holding it in this position from turning, tighten the nut of its fastening.
34. When reassembling, use a new hub nut or a nut from another wheel (so that the old, crushed part a of the nut flange does not fall into the groove b of the outer CV joint tailpiece when punching).
35. After placing the car on the ground, finally tighten the hub nut, lock it and install the decorative cap.
