1 – lower spring support; 2 – dust cover; 3 – upper spring support; 4 – rack support; 5 – self-locking nut, 60–70 Nm; 6 – dust cap; 7 – nut*, 20–30 Nm; 8 – spring; 9 – front suspension shock absorber; 10 – nut, 75–90 Nm.
Warning! * Marks a nut that must be tightened to the specified torque only after the vehicle has been installed on the wheels.
Removal
1. Remove the front wheel.
2. Separate the brake pipe bracket of the brake system from the front suspension strut.
Warning: Do not tear or damage the brake pipe.
3. Unscrew the nuts of the upper rack mount.
4. Unscrew the nuts and remove the bolts securing the strut to the steering knuckle and remove the strut from under the car wing.
5. Installation is carried out in the reverse order of removal.
Disassembly
1. Use a flat-blade screwdriver to remove the dust cover.
2. Using a special tool, compress the front suspension strut spring.

Warning: Use only a reliable tool to compress the spring.
3. Loosen the lock nut at the top of the shock absorber rod.
4. Remove the strut mount, upper spring seat, coil spring, dust boot and lower spring seat.
Examination
1. Check the strut support bearing for wear or damage.
2. Check rubber parts for damage or deterioration.
3. Check the coil spring for deflection and loss of elasticity.
4. Check the shock absorber as follows:
- a. Grasp the shock absorber rod with your hand and push it in and out of the shock absorber several times;
- b. Check that the piston rod moves smoothly, without sticking, and that the force applied to the piston rod does not change with each stroke;
- c. Make sure that there is no extraneous noise when moving the rod.
Assembly
1. Install the lower spring support so that its protrusions enter the holes in the spring plate.
2. Install the dust cover on the shock absorber.
3. Use a special tool to compress the front suspension strut spring. After the spring is fully compressed, install it on the shock absorber.
Warning: Install the coil spring with the marking facing the hinge.
4. Fully extend the shock absorber rod and install the upper spring seat and strut seat.
Caution: Align the D-shaped hole in the upper spring seat with the flat on the shock absorber piston rod.
5. Position the upper and lower ends of the coil spring correctly by fitting them into the recesses and screw on the self-locking nut, but do not tighten it completely.
6. Remove the spring compressor.
7. Tighten the self-locking nut to the specified torque.
Tightening torque: 60–70 Nm
8.Lubricate the upper shock strut bearing and install the dust cap.
Warning: Make sure that no lubricant comes into contact with the rubber parts of the strut support.
