Note: The double row roller bearing is lubricated, adjusted, sealed and maintenance free. Do not attempt to remove the bearing unless absolutely necessary, as it will be damaged during removal. Never overtighten the hub nut by trying to "improve" bearing adjustment "As always".
Note: Bearing removal and installation requires a press, or at least a solid vise and suitable mandrels (big heads). The hub is pressed into the inner race of the bearing with an interference fit. If, when removing the bearing, its inner race remains on the hub, a puller with sharp paws will be required.
1. Place the car on a level surface, turn off the ignition, apply the handbrake and engage first gear (or mode "R").
2. Remove the hub cap and loosen the hub bolt a few turns as described in paragraph 2 of chapter 8.
3. Raise the front of the vehicle and install safety stands. Remove the corresponding wheel.
4. On models with gas discharge headlights (xenon) loosen the clamp and disconnect the vehicle level sensor connector rod from the front lower transverse arm as described in chapter 12.
5. As described in chapter 9, do the following:
- A) Remove the brake caliper from the steering knuckle together with the mounting bracket and hang it on the rack.
- b) Remove the brake disc.
- V) Remove the ABS wheel sensor at the base of the steering knuckle. Release the sensor wiring from all fasteners and take it to the side.
6. Turn away screws and remove a brake board from a rotary fist.
7. Remove the mounting nuts and disconnect the front and rear lower arms from the base of the steering knuckle, using a ball joint remover, as described in paragraph 5. Try not to damage the ball bearing boot.
8. Disconnect the steering tip from the steering knuckle - see paragraph 21.
9. Turn away a fastening nut and take out a collar coupling bolt at the top of a rotary fist, as it is written in paragraph 5. Disconnect the front and rear upper control arm ball joints from the upper part of the steering knuckle, but do not insert any screwdrivers or, even better, a chisel, into the clamp slot, trying to facilitate the removal of the support pins. Take care not to damage the rubber boots of the supports.
10. Grab the steering knuckle and pull it off the drive shaft. If the shaft-hub spline is tight, use a puller.
11. Establish a rotary fist by the basis on bars or a vice. Through a tubular mandrel, relying only on the inner edges of the hub flange, press it out of the bearing. If the inner race remains on the flange, remove it with a puller (see note above).
12. Securely rest the outer surface of the steering knuckle and through the cylindrical mandrel, relying only on the inner race, press the entire bearing out of the fist.
13. Thoroughly clean the hub and knuckle, removing all traces of dirt and grease. Use a needle file to remove any burrs that might interfere with the installation of the bearing. If there are cracks, wear or other damage. parts are to be replaced.
14. Securely rest the steering knuckle with the inner surface of the base and install the bearing in the hole in the fist. The larger diameter inner race should face outward towards the hub flange. Press the bearing into the fist evenly and until it stops, using a cylindrical mandrel, relying only on the outer race.
15. Securely rest the outer surface of the hub flange and install the inner race of the bearing on the hub flange. Through a cylindrical mandrel, relying only on the inner race, press the bearing into the hub until it stops in "hangers".
16. Check up smoothness of rotation of a flange of a nave.
17. Attach the steering knuckle to the installation site and insert the drive shaft into the hub. Install the hub bolt, tightening it at this stage "by hand".
18. Attach the lower wishbones as described in paragraph 5. Install new self-locking nuts and tighten to specified torque.
19. Attach the upper wishbones - see paragraph 5. Insert the tie bolt, screw on a new self-locking nut and tighten to the specified torque. When tightening the nut, press the levers down so that the pivot pins are properly secured.
20. Attach the steering tip - see paragraph 21. Screw on a new fastening nut and tighten it and the adjusting bolt to the prescribed torques.
21. Install the brake shield and securely tighten the mounting screws.
22. As described in chapter 9, do the following:
- A) Install the ABS wheel sensor in the steering knuckle and secure its wiring.
- b) Install the brake disc.
- V) Install the brake caliper.
23. On models equipped with xenon headlights, attach the connecting rod to the lower transverse arm and tighten the clamp as described in chapter 12.
24. Install the wheel, tighten the bolts of its fastening to the prescribed torque and lower the car.
25. Tighten the drive shaft bolt (hub bolt) prescribed moment - see paragraph 2 of chapter 8. Install the hub cap.
26. Finally, check the alignment of the front wheels - this requires specialized equipment, contact a workshop or dealer.
