Possible faults of the front suspension, their causes and methods of elimination.
Noise and knocking in the suspension when the car is moving
Suspension struts are faulty - Replace or repair struts.
The nuts securing the anti-roll bar to the body have come loose. The rubber pads of the struts or bar are worn out — Tighten the nuts, replace the worn pads.
The upper support of the suspension strut has become loose on the body. Tighten the mounting nuts.
Subsidence, tears, peeling of rubber from the upper support housing - Replace the strut support.
Wear of rubber-metal hinges of suspension arms or stabilizer bar struts - Replace hinges.
Worn suspension arm ball joint - Replace ball joint.
Suspension spring settling or breakage - Replace the spring.
Compression buffer corruption - Replace buffer.
Large wheel imbalance - Balance wheels.
Liquid leaking from the rack (rear suspension shock absorber)
Worn or damaged rod seal - Replace seal.
Nicks, burrs on the rod, damage to the chrome coating - Replace the worn or damaged rod and seal.
Shock absorber reservoir sealing ring is seized or damaged - Replace the ring.
Insufficient resistance of the suspension strut (rear suspension shock absorber) during the recoil process
Leaky rebound or bypass valve - Replace damaged valve parts or repair faulty valves.
Insufficient fluid due to leakage - Replace damaged parts and add fluid.
Scoring on cylinder and piston ring - Replace damaged parts and fluid.
Wear or damage to the fluoroplastic layer of the guide bushing or the hole in the shock absorber bushing - Replace the guide bushing.
Recoil valve spring settling - Replace the spring.
Presence of foreign impurities in the liquid - Filter the liquid or replace it.
Insufficient resistance of the suspension strut (rear suspension shock absorber) during compression stroke
Compression valve leakage - Replace damaged valve components or repair faulty valves.
Insufficient fluid due to leakage - Replace damaged parts and add fluid.
Wear of the rod or damage to the fluoroplastic layer of the guide bushing of the strut or the hole in the guide bushing of the shock absorber rod - Replace worn parts.
Presence of foreign impurities in the liquid - Filter or replace the liquid.
Worn, warped or damaged compression valve discs - Replace worn or damaged parts.
Frequent suspension "breakdowns"
Suspension spring settling - Replace the spring.
The stand does not work (rear shock absorber under suspension) — Replace or repair the rack (shock absorber).
Increased clearance in the ball joint
Wear of the rubbing surfaces of the ball joint parts as a result of contamination caused by leaks or damage to the boot - Replace the ball joint.
Vehicle deviation from straight-line motion
Different air pressure in tires - Set normal pressure.
Wheel alignment is incorrect - Adjust wheel alignment.
Destruction of one of the upper suspension strut supports - Replace the support.
Uneven elasticity of suspension springs - Replace the spring that has lost its elasticity.
Significant difference in tire wear - Replace worn tires.
Increased imbalance of the front wheels - Balance the wheels.
Increased tire tread wear
Too sharp acceleration with wheel slippage - Avoid sharp acceleration.
Frequent use of brakes with wheel locking - Avoid sudden braking.
Wheel alignment angles are incorrect - Adjust wheel alignment angles.
Overloading the vehicle - Do not exceed the permissible loads specified in the operating manual.
Uneven tire tread wear
Excessive speed on turn - Reduce speed.
Excessive wear of ball joints of suspension arms and rubber-metal joints - Repair suspension.

Wheel imbalance - Balance wheels.
