Replacing the front suspension hub bearing (Priora 2170)

The 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 hub from the steering knuckle only to replace the bearing.

You will need: a 17 mm wrench, a 30 mm socket wrench (head), pliers for removing retaining rings, mandrels, a large screwdriver, a center punch, and a hammer.

Note: To press in the hub bearing, use the appropriate size mandrels from the kit. If they are not available, you can use the rings from the old bearing.

1. Remove the decorative cap (see "Wheel change").



2. Pry it up with a screwdriver…





3. …and remove the protective cap.



4. Loosen the hub nut.



5. Loosen the hub nut.

6. Place the vehicle on an inspection pit or lift. Remove the wheel (see "Wheel change").



7. Loosen the nuts of the bolts securing the steering knuckle to the strut (see "Removing and installing a telescopic stand").





8. Remove the two bolts securing the ball joint to the steering knuckle.



9. Finally, loosen the hub nut…



10. …and remove the thrust washer.

11. Remove the caliper (see "Removing and installing the front brake master cylinder").

12. Remove the brake disc (see "Removing and installing the front wheel brake disc").



13. Finally, loosen the nuts of the bolts securing the steering knuckle to the strut and remove the bolts.



14. Remove the steering knuckle from the strut bracket.



15. Using a suitable punch, press the hub out of the inner bearing ring.



16. 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.





17. Remove the snap rings from both sides of the steering knuckle.



18. Using a mandrel, press the bearing out of the steering knuckle.



19. Install the outer snap ring.



20. 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.





21. Install the inner snap ring.



22. Using a mandrel, press the hub into the inner bearing ring.



23. Install the steering knuckle in the reverse order of removal. In this case, use a new hub nut or a nut from another wheel (so that the old, crushed parts a of the nut flange do not fall into the groove b on the outer CV joint tailpiece when punching).



24. Finally tighten the 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.
