Every 30,000 km run, check the performance of the shock absorbers. With a decrease in their efficiency, which is manifested in the slow damping of oscillations (3-4 swings) car body when moving unevenness, or the appearance of extraneous knocks from the side of the shock absorbers, contact the service station.
At the same time, pay attention to the condition of the rubber bushings of the shock absorbers and the rubber pads of the anti-roll bar. If the rubber bushings and pads are damaged or hardened, replace them with new ones.
