We remove and repair the shock absorber strut when the upper support, bearing, spring and the telescopic strut itself are worn out
The telescopic stand cannot be repaired - it must be replaced.
For removal and installation you will need keys 13, 17, 19, head 19.
The work is best done on a lift, but can be done on level ground using a jack and safety stand.
It is advisable to replace the wallpaper on the rack, even if only one is faulty.
Stop the vehicle with the parking brake and place wheel chocks under the rear wheels.
Loosen the front wheel bolts.
Raise the front part of the car with a jack and remove the wheel.
Disconnect the tie rod end from the strut swing arm. To do this:
- - turn the steering wheel all the way in the direction opposite to the detachable tip;
- - unbend and remove the cotter pin
Using a 19mm spanner, partially unscrew the ball pin fastening nut.
Inserting a mounting spatula between the swing arm and the tip, press the tip away from the lever and, striking the end of the swing arm with a hammer, press the ball pin out of the lever.
This operation can be performed using a puller.
Finally unscrew the nut securing the ball pin.
And remove the ball pin from the hole in the swing arm
If you are removing the strut for disassembly, loosen the shock absorber rod nut using a special tool or a 22 mm spanner while holding the rod with a 9 mm spanner.
Using a 13 mm spanner, loosen the three nuts securing the upper strut support to the car body.
To minimize the violation of the camber angle of the front wheels, we use a center punch or paint to mark the bolt of the upper mounting of the steering knuckle and the strut bracket.
Using a 17 mm socket wrench, unscrew the nuts of the bolts of the upper and lower fastening of the steering knuckle to the strut, holding the bolts from turning with a 17 mm spanner
Remove the washers from the bolts (the washer of the upper bolt is eccentric) and remove the bolts.
Use a screwdriver or a spatula to remove the steering knuckle from engagement with the strut bracket.
We remove the brake hose from the strut bracket.
Unscrew the nuts securing the upper strut support and remove the strut assembly.
Clamp the stand in a vice and install two spring ties diametrically opposite to each other, so that they engage the four threads of the spring.
Evenly rotating the screws of the couplers, we compress the spring.
After the spring stops pressing on the support cups, use a 22mm wrench to unscrew the rod nut
Remove the travel limiter from the engagement of the upper support.
Remove the upper support.
Remove the bearing protection ring
Remove the compression stroke limiter of the upper support
Remove the upper spring cup assembly with the bearing and spring gasket
Remove the bearing from the upper cup
Disconnect the spring gasket and the upper cup
Remove the upper bearing race.
Remove the spring with ties and the compression stroke buffer with a protective cover.
Before assembling the strut, fully extending and retracting the rod by hand, make sure that the shock absorber is in good condition.
If you feel dips, jerks, or hear strange sounds when moving the rod, replace the shock absorber.
Check the integrity and serviceability of all elements installed on the rack.
Suspension springs are divided into classes. The class of the spring is indicated by paint on the outside of one of its coils.
Springs of the same class must be installed.
We install the spring so that the lower coil of the spring rests against the protrusion of the lower spring support.
We install the upper spring cup with the gasket so that the upper coil of the spring rests against the protrusion of the spring gasket.
When assembling the upper support bearing, add grease to it.
The head of the adjusting bolt for the upper fastening of the steering knuckle to the shock absorber strut is set to its previous position according to the marks.
After assembly, you need to check the toe-in and camber of the front wheels.
