Removing
1. Disconnect the wire «masses» from battery (see «Disconnecting the battery»).
2. Place wheel chocks under the front wheels. Raise the rear of the vehicle and securely jack stands under it (see «Lifting and placing the car on supports»). Remove both rear wheels.
3. Remove the relevant elements of the exhaust system and heat shield (-s), as described in the relevant part of chapter 4.
4. Disconnect the parking brake cables from the leveling plate on the parking brake lever (see chapter 9).
5. Working from under the vehicle, trace each parking brake cable along its entire length and release it from the clips that secure the cables to the underside of the vehicle. Make a note of the cable routing to ensure proper installation.
6. On vehicles equipped with ABS, disconnect the electrical connector for the ABS wheel speed sensors located near the front edge of the rear axle assembly. Release the cables from the clamps on the bottom.
7. To minimize brake fluid leakage, first unscrew the brake fluid reservoir cap and then re-tighten with a piece of polyethylene underneath to ensure a tight seal.
8. Wipe clean the area around the brake line junction box or rear brake pressure regulator and remove the union nuts from the two brake inlet lines (pic. 15.8). Carefully disconnect the brake lines from the junction block or pressure regulator and plug the ends of the lines and open ports. Release the brake line going to the left rear brake from the clips on the bottom.
Pic. 15.8. Loosen the union nuts on the two brake inlet pipes on the junction block
9. Check one last time that all necessary items are disconnected and positioned so as not to interfere with removal, then position a rolling jack under the center of the rear axle assembly. Raise the jack just enough to bear the weight of the bridge.
10. Using a long Torx bit, remove the bolts securing both rear axle supports; access to each of them is possible through a hole in the side member of the bridge, located directly in front of the upper shock absorber support.
11. Turn out two bolts of fastening of each forward support in gathering to the bottom.
12. Lower the jack and remove the axle assembly from its normal position. Remove the bridge from under the car.
13. Inspect the rear axle bearings for signs of damage or deterioration of the rubber section and replace if necessary. Note that all four mounts must be replaced as a set; do not replace supports one at a time.
Installation
14. Installation is carried out in the reverse order of removal, taking into account the following points:
- A) Be careful not to damage the brake lines when installing the underbody axle.
- b) Raise the rear axle to its original position and tighten the support bolts to the specified torque.
- V) Route the brake pipes, parking brake cables and wiring correctly (whichever is applicable) and secure with all necessary clamps.
- G) Tighten union nuts of brake pipelines.
- d) Connect and adjust the parking brake cables as described in chapter 9.
- e) Bleed the air from the hydraulic brake actuator as described in chapter 9.
