1, 3 - top and bottom gasket; 2 - rear suspension spring
Removal option No. 1 (with special equipment)
Attention. To prevent damage to the rubber-metal hinges of the rear suspension arms, it is not allowed to hang the rear suspension arms with tightened joints by an amount exceeding the position of the arms with fully unloaded rear suspension springs.
Attention. When removing, mark the color of the markings of the springs so as not to confuse them during installation.
Place the vehicle on a two-post lift, apply the parking brake and turn off the ignition.
Remove rear wheels.
Remove the rear wheel speed sensor harnesses from the holders on the rear suspension arms.
If special equipment is available: Raise the vehicle, place the transmission rack under the rear suspension arm and lower the vehicle until the spring begins to compress (transmission rack type OMA 604).
Mark the position of the spring on the rear suspension arm support cup.
Loosen the bolt securing the shock absorber to the rear suspension arm (interchangeable head 21, knob).
Figure 3-1 - Removing the rear suspension spring: 1 - upper spring gasket; 2 - rear suspension spring; 3 - lower spring gasket; 4 - rear suspension arms
Raise the car until the rear suspension arm leaves the transmission rack and remove the spring 2, Figure 3-1, together with the bottom gasket 3.
Attention. If the upper gasket 1 of the spring is disconnected, it must be replaced.
Installation
Attention. Do not reuse the shock absorber-to-arm rear suspension bolt. The bolt must be replaced.
Install the lower spring spacer to the rear suspension arm bearing surface.
Install the spring together with the top gasket on the vehicle in the position marked during removal. Start installation from the top of the spring.
Lower the car until the spring begins to compress, connect the shock absorber to the rear suspension arm and tighten, without tightening, a new mounting bolt (interchangeable head 21, knob).
Repeat the removal and installation operations for the second spring.
Install the rear wheel speed sensor harnesses into the holders on the rear suspension arms.
Install rear wheels.
Attention. The final tightening of the bolts for fastening the shock absorbers to the rear suspension arms should be done with the car standing on wheels.
Finally tighten the bolts securing the shock absorbers to the rear suspension arms. Bolt tightening torque 105 Nm (10.5 kgf·m) (interchangeable head 21, torque wrench).
Removal option No. 2 (without special equipment)
It is more convenient to carry out work on a viewing ditch.
We unscrew the bolt of the lower shock absorber to the rear suspension beam arm (see here).
Attention! To avoid damage to the rear wheel brake hoses, do not unscrew the two shock absorber mounting bolts at the same time with the rear of the car hung out.
Hanging the back of the car (on both sides) and fix it on reliable (factory) coasters.
With a mounting spatula, we press the trailing arm of the rear suspension down...
... OR
We pull with both hands the coils of the spring, pressing down on the beam lever...
...and remove the spring.
Remove the lower and upper spring pads. In some cases, the top spring spacer sticks to the body.
We make sure that there are no deformations and gaps on the gaskets. Replace damaged ones with new ones.
Before installing the spring, install the top gasket on it so...
... so that the end of the upper coil of the spring rests on the ledge of the gasket.
Then, so that the top gasket does not move when mounting the spring, we attach it to the spring with tape or electrical tape.
Install the bottom spring spacer onto the arm bracket so that the three rubber studs of the spacer fit into the holes in the arm arm.
When installing the spring, make sure that the end of its lower coil rests against the ledge of the gasket (shown on removed gasket).
Having taken the beam lever down, we put on the upper end of the spring with the gasket on the protrusion of the body bracket. Further installation of the removed suspension elements is carried out in the reverse order.
