Note: Replacing a bearing is a complex procedure, be sure to read the entire chapter before proceeding. You will need a torque wrench and a special puller. When reassembling, use a new hub nut and locking collar.
Removing
1. Loosen the rear wheel bolts, block the front wheels, then jack up and jack up the rear of the vehicle on axle stands. Remove wheels.
2. Remove the bracket and release the brake pipe from the bracket on the diagonal arm. Note that the bracket also supports the ABS sensor wire.
3. Loosen the mounting bolts and remove the brake caliper and ABS bushing bracket from the brake support shield. Move the caliper and ABS sensor bracket to the side and tie them with a sword or wire to the underside of the car.
4. Turn off the fastening screw and remove a brake disk. If necessary, move the hand brake pads away from it by turning the adjuster with a screwdriver inserted through one of the holes in the disc (see Section 9).
5. Using a slotted wrench inserted through one of the non-threaded holes in the hub flange, remove the four brake support shield mounting bolts. Note that the top bolts are shorter than the bottom ones.
6. Use a screwdriver to pry off the plastic cover from the back of the ABS sensor gear to gain access to the rear wheel hub nut (see illustrations).
7. Bend the blocking rim of the hub nut, then remove it from the ABS sensor wheel using a screwdriver as a lever.
8. Thread the two wheel bolts into the hub flange and insert a long metal rod between the bolts to hold the hub stationary. Loosen the hub nut using the socket and the extension rod. Note that the hub nut is extremely tight.
9. Remove the ABS sensor assembly from the hub using a three-legged puller if necessary.
10. Remove the rear wheel hub from the bearing using a puller mounted on the diagonal arm. Note that the bearing inner race may remain on the hub.
11. Remove the bearing circlip from the outer edge of the diagonal arm (see illustration). Then push or knock out the bearing by pressing on the bearing outer race. If required, remove the bearing in the same way as the rear wheel hub (with a puller), bearing in mind that only the outer ring should be pressed.
12. If the ring of the internal bearing remains on a nave, remove it by means of a stripper.
Installation
13. Clean all components and inspect them for signs of wear and damage.
14. Install the new bearing into the diagonal arm by pressing on the outer race of the bearing. If necessary, use a tubular drift or socket with a long bolt, nut and washers to install the bearing. The installed bearing must rest against the shoulder of the lever.
15. Install the bearing circlip, making sure it fits correctly into the groove.
16. Have an assistant support the inner race of the bearing in the diagonal arm (on the back side) using a metal tube, then carefully push the hub into place from the outside. Do not hit too hard with a mallet as the bearing is easily damaged.
17. Install the ABS sensor assembly on the hub. If necessary, have a second person support the outer end of the hub. Be careful not to damage the teeth of the sensor wheel.
18. Install a new hub nut and tighten it to the specified torque while holding the hub stationary as it was removed.
19. Install a new blocking rim on the hub nut and bend it towards the ABS sensor.
20. Install the plastic cover on the back of the ABS sensor.
21. Establish bolts of fastening of a basic board of a brake and clamp them the tightening torque regulated by Specifications. Make sure the shorter bolts are installed at the top of the plate.
22. Install the brake disc and tighten the mounting screw, then apply the handbrake several times to engage the regulator mechanism and move the pads to the correct position.
23. Install the brake caliper and ABS sensor bracket on the support plate and tighten the fastening bolts with a tightening torque regulated specifications.
24. Install the brake pipe into the bracket on the diagonal arm and secure it with the locking bracket.
25. Install the wheel, then lower the vehicle to the ground. Finally tighten the wheel bolts.
