The front hub is equipped with a double-row ball bearing, which does not require adjustment or lubrication during operation. When pressing out the hub, the bearing is destroyed, so press out the front hub from the steering knuckle only to replace the bearing.
1. Remove the protective cap.
2. Loosen the front hub nut. Loosen the wheel bolts and hub nuts with the vehicle on the ground. The hub nut is tightened with a high torque, so it is recommended to use, for example, a piece of pipe as a lever.
3. Remove the wheel and brake disc (see "Removal and installation the front wheel brake disc").
4. Loosen the nuts of the bolts securing the steering knuckle to the strut (see "Removal and installation a telescopic stand").
5. Unscrew the two bolts securing the ball joint to the steering knuckle.
6. Finally, unscrew the two nuts securing the steering knuckle of the telescopic strut and remove the bolts.
7. Completely unscrew the front hub bearing nut and remove the thrust washer.
8. Remove the steering knuckle from the telescopic strut bracket.
9. Using a suitable punch, press the front hub out of the inner bearing race.
10. If the outer part of the inner bearing race remains on the hub, press it off with a puller. For ease of dismantling, there are two special recesses on the hub.
11. Remove the snap rings from both sides of the steering knuckle.
12. Using a mandrel, press the bearing out of the steering knuckle.
13. Install the outer snap ring.
14. Press the new bearing into the steering knuckle using a vice or a press with a suitable mandrel, applying force only to the outer ring of the bearing. Do not hammer the bearing as it may be damaged.
15. Install the inner snap ring.
16. Using a mandrel, press the front hub into the inner bearing race.
17. Install the steering knuckle on the vehicle in the reverse order of removal. In this case, use a new front hub nut or a nut from another wheel (so that the old, crumpled parts a the flange of the nut did not fall into the groove when punching b on the outer CV joint tailstock).
18. Finally tighten the front hub nut in the same way as the wheel bolts, with the vehicle on the ground, and lock it in two places. Install the protective cap.
