Removing
1. Unscrew the cap of the brake fluid reservoir, close the hole with polyethylene and wrap the cap again. This prevents most of the oil from escaping from the brake system.
2. Place a lift under the center of the rear axle and raise the axle slightly.
3. Loosen the nuts on the end of the parking brake equalizer to disengage the ends of the cables from the equalizer.
4. Disconnect both cables.
5. Remove the lock plates from the bracket on the chassis and slide the cables down.
6. The fastening of the cables on the equalizer of a car with leaf springs is shown in the illustration. This mount looks exactly the same on a three-door car. In a five-door car, the mount has a similar appearance.
7. Disconnect the parking brake cables from the bracket on the chassis. Fastening is carried out by four locking plates with bolts.
8. Turn away a cap nut of connection of a brake hose with the brake pipeline and take out the pipeline.
9. Seal the end of the pipeline from dirt (e.g. duct tape).
10. Now the brake hose can be disconnected from the elbow.
11. Remove the lock plate with a mandrel and pliers.
12. Mark both flanges of the propshaft connection with paint as shown, and remove the four bolts and nuts (let the paint dry first).
13. Disconnect the driveshaft from the axle drive gear flange, supporting the driveshaft so that it does not fall. You can secure the shaft with wire to the chassis or put something underneath.
14. Disconnect the brake pressure regulator connecting rods from the bracket on the rear axle. The fastening is shown in the illustration.
15. The following work is carried out in accordance with the illustration on both sides of the vehicle. First, disconnect the parking brake cables by removing the locking plates (1). Loosen the anti-roll bar connecting rod nuts (2) and unscrew the nut (3) and removing the washer from the trunnion, remove the shock absorber.
16. Disconnect the ventilation hose from the bridge.
17. Slowly lower the lift, releasing the shock absorbers.
18. Remove the springs and upper spring shims.
19. Unscrew the fastening nut from the support pin and remove the transverse torque rod shown in the illustration.
20. Loosen the ABS yaw rate sensor cable bolt on the middle control arm. The plug connection and the cable are also fixed to the chassis.
21. Loosen the bolt to disconnect (3), shown in the illustration. The middle axle arm can now be disconnected. To do this, unscrew the bolt (1) and a nut.
22. Disconnect the trailing arm from the bridge. To do this, unscrew the two bolts with nuts on each side of the car. Carefully knock out the bolts. Since the bridge is no longer attached, it must be secured on the lift with the help of an assistant.
23. Carefully roll out the axle on the lift from under the vehicle.
Installation
The bridge is installed in the reverse order of removal. In doing so, keep in mind the following:
It may happen that when installing a new axle, it will be necessary to transfer the brake hoses and pipelines, as well as the parking brake cables from the old axle.
Rubber-coated mounting elements must not be exposed to lubricants. Also do not keep lubricants near the indicated places.
1. Bolts and nuts for fastening all mounting elements with a rubber coating, first tighten by hand.
2. After lowering the car on the wheels, tighten these connections to the specified torques.
3. Bring the rear axle on the lift under the car (while the bridge must be held) and stop it near the ends of the trailing arms.
4. Connect both trailing arms in the places shown in the illustration.
5. As stated above, hand tighten only. Trailing arms must move.
6. Install the middle lever again as illustrated.
7. Attach the ABS cable to the lever and tighten the ABS plug bracket bolt to 26 Nm.
8. Do not tighten the middle arm bolt and nut yet.
9. Install the transverse torque rod as illustrated. There should be a washer under the nut. Don't tighten the nut just yet.
10. Install the helical springs with the top insulating pads on the bridge.
11. Raise the bridge slowly, making sure the springs are in the correct position at the bottom and top.
12. Raise the bridge now so that the springs are clamped.
13. Install a shock absorber on the axle. screw (3) rolls with the puck. connecting rods (2) fastened to the bridge with nuts. The parking brake cables are attached to the trailing arm with clamps (1) and bolts (9 Nm).
14. Connect the brake pressure regulator links to the axle.
15. Fix the brake hose on the angle, insert the brake pipe and fix it.
16. Attach the parking brake cables to the chassis brackets.
17. Tighten all bolts to 9 Nm.
18. Attach the parking brake cables to the equalizer and clip to the bottom of the chassis.
19. Connect the flange of the propeller shaft with the flange of the final drive gear in accordance with the marking.
20. Insert new bolts and tighten them to 75 Nm.
21. Install and secure the rear wheels.
22. Lower the car onto its wheels.
23. Now tighten the suspension mounting elements with rubber parts with the following torques.
24. Finally, tighten the brake drum mounting bolts.
25. Bleed the brake system as described in Chapter 9.
26. Adjust the parking brake.
27. Check the oil level in the rear axle. Add oil if necessary.
