Adjustment

Specifications & Adjustments For Wheel Alignment

Use self-locking bolts and nuts with plastic coating (micro-encapsulated) only once. Refinish threads with tap prior to screwing in self-locking bolts.

Shock Absorbers

1. Remove trunk lining. Remove nut and rubber ring of upper shock mount. Raise car on rear axle.

2. Remove holding clamps on spring link and Remove cover. Remove lower shock absorber mounting bolt. Pull shock absorber downward and Remove from vehicle.

Caution: When removing gas shock absorbers while car is raised and axle tension relieved, do not rotate piston rod while loosening main strut nut. This could result in the sudden extension of the piston rod.
Removal

To install, reverse extraction procedure.

Coil Springs

1. Raise car and Remove rear wheel. Remove holding clamps of spring link cover and Remove cover. Insert Spring Tensioner 201 589 00 31 00 with spring Tensioning Plates 201 589 00 63 00. Compress spring until spring link is free of load.

2. Remove shock absorber as previously outlined. Remove rear spring with rubber mount. To install, reverse extraction procedure.

Use greatest caution when removing gas pressurized shock absorbers.
Removal & Installation

Removal Rear Suspension & Axle

1. Raise car and retain with security stands. Remove wheel assemblies. Disconnect exhaust ideas at flange connection. Remove intermediate lever of parking brake and disconnect cable controls.

2. Disconnect both brake lines and seal. Loosen clamp nut of drive shaft and intermediate bearing on frame floor and remove. Disconnect rear of drive shaft and slide forward, out of centering position. Wire drive shaft to brake cable holder.

3. Remove spring link covering. Remove shock absorbers and coil springs. Loosen torsion bar relationship toward rear axle and remove.

4. On vehicles with Abs, drain rear axle. Remove Rpm sensor from rear axle housing. Cover magnetic edge of Rpm sensor.

5. On vehicles with auxiliary heater, Remove electric fuel pump and suspension plate of exhaust. Remove the cable connector from rear axle cross member. Raise rear axle assembly to lift stop. Force water drain hose out of rear axle carrier.

6. On vehicles with Cis-E fuel injection system, pinch fuel suction hose in the middle of fuel tank and fuel pump with a clamp. Loosen clamp on fuel hose to accumulator and pump. Remove fuel hose.

7. On all models, Remove front and rear rubber mounts on frame floor and Remove with stop plate. Lower the rear axle assembly from vehicle.

Camber Strut

1. Raise car and retain with security stands. Rubber mounts of camber strut cannot be supplanted individually. If rubber mounts are damaged, replace camber strut.

2. Remove strut-to-axle carrier bolt. Remove strut-to-wheel carrier bolt. Force clamping sleeve of strut out of wheel carrier.

3. Remove camber strut at axle carrier while pulling slightly outward on wheel carrier. Remove strut in a downward direction.

To install, reverse extraction procedure. Bleed brake ideas and adjust parking brake. Ensure differential is filled to proper level.

To install, reverse extraction procedure. Axle shaft must be horizontal prior to tightening camber strut nut.

Pulling Strut

1. Raise car and retain with security stands. Rubber mounts of pulling strut cannot be supplanted individually. If rubber mounts are damaged, replace pulling strut.

2. Mark position of eccentric bolt in relation to axle carrier. Using Wrench 201 589 00 03 00, Remove strut-to-axle carrier nut. Prior to pulling out eccentric bolt, push wheel carrier in transmit direction to slacken.

3. Remove strut-to-wheel carrier bolt. Force clamping sleeve of pulling strut out of wheel carrier. Remove pulling strut.

1. Raise car and retain with security stands. Remove rod-to-wheel carrier nut. Using Puller (201 589 01 33 00) and Thrust Piece (201 589 05 63 00), force track rod from wheel carrier.
2. Mark position of eccentric bolt in relation to axle carrier. Remove rod-to-axle carrier nut. Remove cam disk, eccentric bolt and track rod.

To install, reverse extraction procedure. Grease from ball pin and conical seat in wheel carrier. Hold ball pin with an Allen wrench while tightening. Axle shaft must be horizontal prior to tightening tracking rod-to-axle carrier nut.

Pushing Strut

1. Raise car and retain with security stands. Remove pushing strut cover. Rubber mounts of pushing strut cannot be supplanted individually. If rubber mounts are damaged, replace pushing strut. Remove strut-to-axle carrier bolt. Remove strut-to-wheel carrier bolt with washer and contour disk.

2. Turn strut on rear axle carrier downward. Force clamping sleeve out of wheel carrier. Remove pushing strut.

To install, reverse extraction procedure. Axle shaft must be horizontal prior to tightening pushing strut nuts.

Spring Link

1. Raise car and retain with security stands. Remove spring link cover. Remove lower shock absorber bolt. Remove torsion bar from spring link. Remove coil spring as previously outlined.

2. Remove spring link-to-axle carrier bolt. Remove spring link-to-wheel carrier bolt. Remove spring link.

To install, reverse extraction procedure. Axle shaft must be horizontal prior to tightening spring link nuts.

Wheel Carrier

1. Loosen collar nut fastening rear axle shaft prior to lifting car and removing wheel. Using Remover (201 589 00 61 00), Remove rear axle shaft out of rear axle shaft flange.

2. Remove brake caliper and hang out of way using a hook. Remove brake disc. Remove intermediate lever of parking brake and disengage cable control. Pull out lock on hand brake cable.

3. Remove camber strut-to-wheel carrier bolt. Force clamping sleeve of strut out of wheel carrier. Remove pulling strut-to-wheel carrier bolt. Force clamping sleeve of pulling strut out of wheel carrier.

4. Mark position of eccentric bolt of pulling strut in relation to axle carrier. Using Wrench (201 589 00 03 00), Remove strut-to-axle carrier nut. Remove unblemished pulling strut.

5. Remove track rod-to-wheel carrier nut. Using Puller (201 589 01 33 00) and Thrust Piece (201 589 05 63 00), force track rod from wheel carrier.

6. Mark position of eccentric bolt of track rod in relation to axle carrier. Remove rod-to-axle carrier nut. Remove cam disk, eccentric bolt and unblemished track rod.

7. Remove nut of pushing strut on wheel carrier and Remove with washer, contour disk and bolt. Force clamping sleeve out of wheel carrier.

8. Remove nut on spring link and Remove from wheel carrier. Pull unblemished wheel carrier from rear axle shaft.

1. To install, reverse extraction procedure. If position of eccentric bolts were not marked for pulling strut and track rod, position eccentric bolts in center position.

2. Prior to tightening any nuts axle shaft must be in horizontal position. Clean grease from ball pin and conical seat of track rod. Check toe-in and track angle of rear wheels.
