Pic. 4.42. Rear shock absorber
Withdrawal
Remove rear wheels.
Remove the safety cover located in the trunk.
Disconnect the brake hose and wheel speed sensor wire from the rear suspension strut.
Remove stabilizer links.
Pic. 4.43. Bolts of fastening of a back rack of a suspension bracket
Remove the two bolts securing the rear suspension strut to the rear wheel knuckle (pic. 4.43).
Attention! Be careful not to drop the rear rack.
Remove the rear strut assembly from the vehicle.
Disassembly
Pic. 4.44. shock absorber spring compression
With a special tool (J38402, A-20 and A-50) compress the strut spring so that the impact on the spring cups is minimal (pic. 4.44).
Note. Do not use pneumatic tools (impact wrench).
Loosen the self-locking nut on the upper end of the damper rod.
Remove the strut damper, upper spring cup, spring, and protective boot from the strut assembly.
Examination
Check the strut damping mount for wear or damage.
Check rubber parts for damage or deterioration.
Check the spring and strut assembly for wear or deformation (sagging and stiffness reduction).
Pic. 4.45. Shock absorber check
Check the shock absorber for abnormal resistance to the movement of the rod and extraneous noise (pic. 4.45).
Assembly
Pic. 4.46. Installing the lower spring spacer
Install the lower spring spacer so that the tabs on it are aligned with the holes in the lower spring cup (pic. 4.46).
Install the protective cover on the shock absorber.
Pic. 4.47. Spring compression
With a special tool (J38402, A-42) compress the spring (pic. 4.47).
Extend the shock absorber rod until it stops, install the upper spring cup and strut damping support assembly.
Pic. 4.48. Alignment of the flat part of the D-hole of the upper spring cup
Note. Align the flat part of the D-hole of the upper spring cup with the flat part of the threadless part of the damper rod (pic. 4.48).
Pic. 4.49. The combination of the upper and lower coils of the spring
Align the top and bottom coils of the spring with the corresponding notches on the top and bottom strut spring cups, then temporarily tighten the self-locking nut (pic. 4.49).
Attention! Replace the self-locking nut with a new one after removal.
Pic. 4.50. Position of damping strut mount
When installing, position the damping support of the rack so that its bolt is aligned with the protrusion of the upper spring cup, as shown in Figure 4.50.
Remove special tool (J38402, A-20 and A-50).
Tighten the self-locking nut to a nominal torque of 40–55 Nm.
