Contents: Removal ↓ Installation ↓
Since the vehicle must rest its wheels on the ground when tightening the silent blocks, a suitable lift, viewing platform or overpass is required to perform this operation.
Removal
Place the car on a lift.
Remove one bolt and two nuts connecting the ball joint to the suspension arm.
Disconnect the anti-roll bar support.
Cars produced before 4/87
Cars from 5/87 year of production
Remove the bolts and nuts from the rear silent block of the wishbone suspension.
Disconnect the front silent block of the transverse suspension arm and remove the arm.
Note: Cars from 5/87, with automatic transmission: The left suspension arm cannot be removed separately. The axle beam must be removed as a set. Dismantling is performed as follows:
Disconnect the left and right arms at the ball joints.
Disconnect the rear left and right control arm holders.
Remove the stabilizer.
Place a shop jack under the cross beam to prevent it from falling after the fasteners are removed. It is recommended that this operation be performed with the help of an assistant.
Remove 6 bolts and two nuts and remove the cross beam together with the suspension arms.
Disconnect the levers from the cross beam.
Checking and replacing the rear silent block.
Check the suspension arm silent block for porosity and damage.
Remove the nut, snap ring and bushing.
Install the new bushing and retaining ring, aligning the bushing vertically with the lever.
Tighten the nut: for vehicles produced before 4/87 with a force of 85 Nm, for vehicles produced since 5/87 - with a force of 135 Nm.
Installation
Install the lever on the beam. Screw on the bolts and nuts without tightening them.
Left suspension arm for vehicles produced since 5/87 with automatic transmission: Install the beam with the arms fixed to it on the body bottom. Tighten the mounting bolts, see Figure G-3624.
Install the stabilizer without tightening its mounting bolts.
Tighten 1 bolt and 2 nuts securing the wishbone to the steering knuckle. Tightening torque: for vehicles up to 4/87 - 65 Nm; for cars produced since 5/87 - 140 Nm.
Remove the car from the lift.
Press the car down manually several times to settle the suspension.
Tighten the stabilizer mounting bolts.
Cars produced up to 4/87: Tighten the front wishbone support mounting bolts to 115 Nm, and the rear support bolts to 90 Nm.
Vehicles from 5/87: Tighten the front wishbone support mounting bolts to 235 Nm, and the rear crossmember bracket to the torque shown in Fig. G-3628.
Measure the geometric parameters of the front suspension in a specialized workshop. Perform the operation as soon as possible.
