Replacing shock absorbers is a key maintenance procedure, crucial not only for driving comfort but, above all, for road safety. Unfortunately , even experienced mechanics can make mistakes during installation , and drivers often ignore the signs of suspension wear. This can lead to serious consequences of incorrectly replaced shock absorbers, such as reduced traction, longer braking distances, and accelerated tire wear. It's worth knowing the most common mistakes mechanics make – shock absorbers are components that require high precision and adherence to manufacturer recommendations.

One of the most common questions asked in workshops is: should shock absorbers be replaced in pairs? The answer is yes. They should always be replaced as a complete set on the axle – both front and rear . Installing just one new component causes uneven suspension operation, which negatively impacts vehicle stability. In passenger cars, this manifests as a pull to one side, and in trucks, it further compromises the safety of the cargo being transported. This is a key mistake when replacing shock absorbers, which also results in accelerated wear of other suspension components.
Every step of the installation process requires precision. Common problems include errors in front and rear shock absorber installation, such as:
improper tightening of mounting screws,
omitting the replacement of cushions and covers,
the use of low-quality parts that quickly lose their properties,
no check of the condition of suspension springs and bearings.
It's worth remembering that shock absorbers can exhibit very similar symptoms of wear and tear, including knocking noises while driving, reduced cornering stability, and uneven tire tread wear. Therefore, after each installation, a test drive and suspension operation inspection are essential .
In the case of trucks and delivery vehicles, the stakes are even higher, as replacing shock absorbers in trucks – advice applies not only to the safety of the driver but also to the entire fleet and the goods being transported. Trucks operate under heavy loads, so shock absorbers must be installed according to rigorous procedures. Inspecting the associated components – bushings, pins, and springs – is crucial. How can you recognize improperly installed shock absorbers in a truck? This is most often caused by excessive cab roll, braking problems, or noticeable vibrations at higher speeds.
Replacing shock absorbers should always be followed by checking wheel alignment. This is an element often overlooked by garages, yet it has a significant impact on vehicle stability and even tire wear. Neglecting this aspect is a classic example of an error when replacing shock absorbers, resulting in additional costs and accelerated tire wear . Shock absorbers and suspension geometry – typical problems also include vehicle pulling, lack of steering precision, and increased fuel consumption.
Improper installation is not only a technical problem but also a real hazard on the road. The consequences of incorrectly replaced shock absorbers include: longer braking distances, reduced traction in corners, unsafe vehicle behavior on uneven surfaces, and accelerated wear of other suspension components. Furthermore, trucks and construction machinery can experience a loss of stability during material transport , which is particularly dangerous in road traffic and on construction sites.
