Suspension failures

Suspension failures

Modern car manufacturers pay great attention to the reliability and comfort of the suspension. In addition to this, many cars imported and sold in our country are equipped with reinforced suspension (increased ground clearance, increased spring stiffness). But the quality of roads negates these efforts, and the motorist is periodically faced with suspension malfunction. If it doesn’t make sense to change the suspension, then give the car here:

The following suspension malfunctions are distinguished:

Faulty front wheel alignment (camber);
deformation of the suspension arms;
decreased stiffness (looseness) or breakage of a spring;
Damage of the shock absorber support;
Damage to the damper support;
bushing wear or damage of anti-roll bar;
Wear of rubber-metal or ball elements of suspension mounts.
The main cause of these failures, as indicated above, is the quality of the road surface. At the same time, the service life of suspension components may be considerably shortened by poor-quality components, unskilled maintenance and repair work, and driving style.

Suspension malfunctions may occur unexpectedly (for example, when hitting an obstacle) or appear gradually. Some failures, if not corrected in time, may be the cause of other, more serious failures.

The occurrence of suspension malfunctions is indicated by various indirect symptoms:

Deviation of the vehicle from a straight-line movement (sideways drift);
When you turn or brake, the vehicle will wobble (sway);
oscillation during driving;
a knocking noise in the suspension during driving;
Suspension “breakdown”;
excessive or uneven wear of tires.

When determining suspension malfunctions, note that these external signs also accompany steering malfunctions. Determination of a particular suspension malfunction is usually performed by detailed inspection, testing and defect inspection of the suspension components.

A number of the above-mentioned external signs are manifested by deviations in the operating characteristics of the vehicle wheels (tire pressure, balancing, tire wear degree, hub bearing wear degree). Thus, due to low tire pressure the car is driven sideways, there is a vibration in motion. Wrong wheel balancing is also accompanied by vibration and sometimes knocking in suspension. Therefore, when diagnosing suspension malfunctions, issues related to wheel imbalance should be excluded first.

It is not advisable to operate the vehicle with a faulty suspension, as it may cause an accident.
