Note. The following procedures require a press, suitable mandrels and pipes.
Removing
1. Jack up the front of the vehicle on the appropriate side and place it on jack stands placed under the chassis frame and front axle assembly.
2. Remove the corresponding front wheel.
3. At the corresponding complete set give bolts of the stabilizer of cross stability and remove an arm from the trailing arm which is subject to replacement.
4. Loosen the nut from the rear end of the trailing arm, remove the washer and bushing (see accompanying illustration). Disconnect the steering linkage ball joint from the steering knuckle on the appropriate side of the vehicle.
1 - nut; 2 - bushings; 3 - washers; 4 - trailing arm
6. Give nuts of bolts of fastening of the trailing arm to a basic arm of the bridge.
7. Get the jack under the front axle, then cock it, removing the load from the bolts of the trailing arm.
8. Remove the bolts by knocking them out with a brass punch (support the bar while driving out the bolts)
9. Lower the boom away from the axle and remove the rear end of the boom from the support bracket on the chassis.
10. Inspect the trailing arm for cracks and signs of deformation, replace if necessary.
11. Check up a condition of plugs in the trailing arm. Replace defective bushings (see accompanying illustration):
1 - pipe; 2 - mandrel; 3 - trailing arm
- Support the rod under the sleeve to be replaced with a piece of pipe of suitable diameter (the sleeve must pass freely through the pipe).
- Using a tool whose mandrel will rest against the inner steel tube of the bushing, press the bushing out of the stem.
- Moisten the outer surface of the new bushing with soapy water and begin to gradually push the bushing into its seat using a piece of pipe that will rest against the outer steel tube of the bushing.
- Make sure the bushing is square and centered.
Installation
Installation is in the reverse order.
1. If bushings have been replaced, carefully check the condition of the rod axle bolts. Replace worn components.
2. Install the trailing arm on the car, install the fasteners (nuts, washers and rubber bushings), but do not completely tighten it at this stage. Lower the car to the ground.
3. Rock the car several times to shrink the suspension components, then tighten the chassis nut with a force of 93÷123 Nm. Tighten the bridge nuts with a force of 157÷216 Nm.
4. Reinstall the anti-roll bar.
