Brake the car with the parking brake and install the anti-rollback stops ("shoes") under the rear wheels.
Loosen and tighten the wheel mounting bolts only with the vehicle on the ground. The tightening torque of the bolts is 65–95 N·m (6.5–9.5 kgf·m).
2. Loosen the ball joint mounting nut.
3. Use a puller to press the ball joint pin out of the lever. Learn more see subsection 6.1.9, paragraphs 3–4.
4. Loosen the rear strut mount nut.
5. Loosen the mounting nut and disconnect the anti-roll bar from the control arm.
6. Loosen the nut securing the lever to the body bracket and remove the bolt.
7. Remove the lever.

Carefully inspect the suspension arm and replace it in the following cases: a) the geometry of the arm is damaged; b) rubber-metal hinges are torn, bulging on one side, or their rubber has lost its elasticity.
Replacing the rubber-metal hinges of the lever requires special tools and skills. In a garage, it is easier to replace the entire lever assembly.
8. Install the lever in the reverse order. Lower the car to the ground and rock it vigorously several times. Tighten to the appropriate torques: nuts securing the ball joint to the lever and the lever to the body bracket – 80–96 N·m (8.0–9.6 kgf·m), nut securing the tension rod to the lever – 160–180 N·m (16.0–18.0 kgf·m), nut securing the anti-roll bar strut to the lever – 42–52 N·m (4.2–5.2 kgf·m). After driving 100 km, tighten these threaded connections again to the required torques.
