Cause of malfunction | Remedy |
Noise (knock) in the suspension when the car is moving | |
Faulty suspension struts The bolts securing the anti-roll bar to the body have loosened. Wear of rubber pads stretch marks or rods Weakened mounting of the upper support of the suspension strut to the body Draft, destruction of the rubber element of the rack support Wear of silent blocks (rubber-metal joints) suspension arms, braces or stabilizer bar struts Suspension arm ball joint wear Suspension spring settling or failure Stroke Buffer Destruction Large wheel imbalance | Replace or repair suspension struts Tighten bolts, replace worn tie rods or rods Tighten the nuts securing the upper support of the suspension strut to the body Replace rubber strut support Replace silent blocks (rubber-metal hinges) suspension arms, braces or stabilizer bar struts Replace suspension arm ball joint Replace suspension spring Replace compression stroke buffer Contact a tire shop for wheel balancing |
Fluid leaking from rack (rear shock absorber) | |
Wear or destruction of the rear strut stem seal (shock absorber) Nicks, scuffs on the rack rod (shock absorber), chrome damage Shrinkage or damage to the O-ring of the C-pillar housing (shock absorber reservoir) | Replace rear strut stem seal (shock absorber) Replace worn or damaged stem and packing Replace rear strut housing o-ring |
Insufficient suspension strut resistance (rear shock absorber) during recoil | |
Recoil valve or rear strut bypass valve leak Insufficient liquid due to leakage Seizures on the cylinder and piston ring Wear or damage to the fluoroplastic layer of the guide bush Recoil valve spring settlement The presence of impurities in the liquid | Replace damaged parts or repair them Replace damaged parts and refill fluid Replace damaged parts and fluid Replace guide bushing Replace recoil valve spring Filter the fluid or change it |
Insufficient suspension strut resistance (rear shock absorber) during compression | |
Rear strut compression valve leak Insufficient amount of fluid in the rear pillar due to a leak Stem wear or damage to the fluoroplastic layer of the guide bush The presence of impurities in the liquid Wear, deformation or destruction of compression valve disks | Replace damaged parts or repair them Replace damaged parts and refill fluid Replace worn parts Filter or change fluid Replace worn or damaged discs |
Frequent «breakdowns» pendants | |
Suspension spring settlement Stand not working (rear shock absorber) | Replace suspension spring Replace or repair rack (rear shock absorber) |
Increased clearance in the ball joint | |
Wear of the rubbing surfaces of the parts of the ball joint as a result of contamination caused by leakage or damage to the boot | Replace ball joint |
Driving the vehicle away from straight ahead | |
Different air pressure in tires Violation of wheel alignment angles (collapse, convergence) Destruction of the rubber element of one of the suspension strut supports Unequal elasticity of suspension springs Significant difference in tire wear Increased front wheel imbalance | Set normal pressure Adjust wheel alignment (collapse, convergence) Replace suspension strut rubber Replace a suspension spring that has lost elasticity Replace worn tires Contact a tire shop for wheel balancing |
Increased tire tread wear | |
Too sharp acceleration of the car with wheel slip Frequent use of wheel lock brakes Wheel alignment misaligned (collapse, convergence) Car overload | Avoid hard acceleration When braking, do not bring the wheels to block Adjust wheel alignment (collapse, convergence) Do not exceed the permissible loads specified in the vehicle manual |
Uneven tire tread wear | |
Increased vehicle speed on a curve Large wear of ball joints of suspension arms and silent blocks (rubber-metal joints) Wheel imbalance | Reduce your speed when cornering Repair suspension. Replace the ball joints of the suspension arms and silent blocks Contact a tire shop for wheel balancing |
