Removing the shock absorber without other suspension parts is carried out as follows:
- loosen the wheel nuts, jack up the car and remove the wheel;
- remove the fastening elements of the brake pipeline from the shock absorber (two bolts);
- unscrew the disc wheel brake caliper and tie it firmly with wire to the front suspension so that it does not hang on the brake hose;
- Disconnect the connector if the brake lining wear indicator is installed;
- Disconnect the spherical joint of the transverse steering rod from the steering knuckle arm;
- in the presence of ABS, remove the wheel speed sensor (one bolt);
- Disconnect draft of the stabilizer of cross-section stability;
Pic. 202. Unscrewing the upper stop of the shock absorber strut
- unscrew the upper stop of the shock absorber strut, for which insert a wrench with an internal hexagon «by 8 mm» into the piston rod and unscrew the nut with a socket head, as shown in fig. 202;
- unscrew the clamp bolt on the rear side of the shock absorber and use a strong screwdriver to open the clamping slot of the steering knuckle while pressing down on the transverse arm together with the steering knuckle so that the rear side of the shock absorber strut comes out of the steering knuckle (do not press hard, so as not to damage the constant velocity joints of the drive shaft);
- if the car is equipped with an electronic suspension adjustment device, then an additional wire is supplied to the shock absorber, disconnect it from the wire fastening bracket, then disconnect the plug connector;
- Take out a shock-absorber rack from below from the car.
If it is necessary to remove the shock absorber assembly, work only on the right side, as the left transverse arm can only be disengaged after the subframe has been removed. In this case, follow the relevant descriptions for removing the drive shaft, control arm, etc.
Installation is carried out in the reverse order of removal, taking into account the following:
- Connect the shock absorber to the steering knuckle, insert the clamping bolt and tighten to 85 Nm;
- insert the upper safety stop, tighten the nut as shown in fig. 202, torque 46 Nm;
- fasten the rear transverse arm to the subframe (only the right side with the complete removal of the shock absorber strut);
- Connect the tie rod, tighten the nut to 37 Nm;
- Connect and tighten the anti-roll bar mounting to 50 Nm;
- connect the brake hose, in this case bleed the brake system as described in the relevant section, otherwise connect the hose holder (50 Nm);
- Connect the ball joint of the transverse suspension arm to the steering knuckle, if it was removed, and tighten the bolt to 85 Nm;
- if necessary, install a wheel speed sensor (ABS) and tighten the sensor mounting bolt to a torque of 10 Nm (this also applies to the plug connector of the electronic suspension control - insert it and secure the wire);
- tighten a support of the disk wheel brake mechanism and tighten bolts;
- plug in the connector for the brake lining wear monitor (if available);
- check that the brake hose does not twist when turning the wheels (not stretched);
- lower the vehicle onto the wheels and tighten the wheel nuts to 85 Nm.
Spare shock absorber parts may have different part numbers and should therefore only be ordered from the relevant spare parts catalogues.
