Pic. 7.2. Strut strut details: 1 - a cap of a nut of the top fastening; 2 - a nut of the top fastening of a shock-absorber rack; 3 - thrust washer; 4 - top support of the rack; 5 - shock absorber rod nut; 6 - upper support cup; 7 - protective cover; 8 - compression stroke buffer; 9 - shock absorber; 10 - lower spring gasket; 11 - spring
You will need; keys «at 24», TORX T50 and spring compressor.
1. Remove the shock absorber from the car (see «Removal and installation of shock absorber front suspension strut»).
2. Install the spring compressor and compress the spring.
3. Unscrew the stem nut, holding the stem from turning with a second wrench...
4.... and remove the nut
5. Remove the top support...
6....upper support cup...
7.... a spring with a protective cover.
8....compression buffer...
Note: Replace springs only in pairs (right and left at the same time).
9.... and the gasket of the lower spring cup.
10. Inspect the rack parts. If cracks, deformation, or damage are found on the strut housing or lower spring cup, replace the strut. Welding work on the stand is prohibited.
11. Install the shock absorber vertically and lower and raise the shock absorber rod several times until it stops. Make sure that the stem moves without dips, jams and knocks. Otherwise, replace the shock absorber. Also, replace the shock absorber if fluid leaks are found (slight sweating in the upper part of the case is allowed) and if the threads in the upper part of the stem are damaged.
Warning: Replace shock absorbers only in pairs (right and left at the same time).
12. Replace the compression stroke buffer if damaged.
13. Replace the upper support in case of severe deformation or local buckling of the rubber array.
14. Install the parts in the reverse order of removal.
Note: When installing the spring, make sure that the end of the lower coil rests against the special protrusion of the lower spring cup.
Finally tighten the strut top nut with the vehicle on the ground to the torque specified in annex 1.
Recommendation: After repairing the front suspension strut, check and, if necessary, adjust the wheel alignment (see «Checking and adjusting wheel alignment»). Use the services of workshops with special equipment.
