Comment. It is convenient to perform work on a viewing hole. But if necessary, you can remove and install the spring and shock absorber of the rear suspension by placing the car on a flat horizontal platform.
Recommendation. Replace dampers and springs in pairs.
You will need an assistant to complete the work, as well as:
- viewing hole or flyover;
- stand.
Removing
1. We prepare the car for work and hang the rear of the car on stands (see "Preparing the car for maintenance and repair").
Comment. In the absence of a pit or overpass, remove the rear wheel of the car from the side of the shock absorber to be replaced (see "Wheel - replacement").
2. Remove the side trim of the trunk from the side of the shock absorber to be removed (see "Tailgate - removal and installation").
Recommendation. The following operation is best performed with a special tool for disassembling the suspension strut (see "Front suspension strut - disassembly and assembly"), since it is not always possible to hold the stem with an open-end wrench.
3. Hold the shock absorber rod with an open end wrench by 6 mm, ring wrench by 17 mm unscrew the stem nut.
4. Remove the support washer and the upper rod mounting pad from the shock absorber rod.
5. Two keys by 19 mm unscrew the nut of the bolt securing the lower end of the shock absorber to the rear axle beam and remove the bolt.
6. We take the lower end of the shock absorber towards the rear of the car and remove the shock absorber.
7. Remove the spring and its gasket from the shock absorber, and, if necessary, remove the lower cushion and spacer from the shock absorber rod.
Installation
Comment. In the rear suspension of the car, springs of the same class should be installed. Class A is marked with white marks, and class B is marked with black (for vehicles supplied for export, marking in yellow and green, respectively).
1. Before installing the shock absorber, we fix the rubber gasket on the spring with insulating tape or tape.
2. We install the spring on the shock absorber and fully extend the shock absorber rod. We put on the stem the spacer sleeve and the bottom pillow (if they are not on stock).
Warning! We orient the shock absorber so that the end of the lower coil of the spring is facing the wheel.
3. We introduce the shock absorber rod into the hole of the body cup, at the same time the assistant puts a special washer on the rod and puts on the rod nut for several turns.
4. Raise the lever until the holes in the shock absorber and the beam bracket are aligned. Install the shock absorber lower mounting bolt and tighten its nut (without delay).
Comment. In the absence of an assistant, you can first fix the shock absorber on the rear suspension beam. Then, substituting the stop under the rear lever, we lower the car smoothly on the jack, while controlling that the shock absorber rod enters the hole in the body, and after that we put on the top pillow with a washer and bait the nut.
5. Install the removed wheel (if the work was carried out without a viewing hole) and put the car on wheels. We press the rear of the car several times to self-install the suspension elements.
6. Tighten the shock absorber rod mounting nut to a torque of 50-61.7 N·m (5.1-6.3 kgf·m).
7. Tighten the nut of the shock absorber lower mounting bolt to a torque of 66.6-82.3 N·m (6.8-8.4 kgf·m).
