Although they are not immediately visible at first glance, they play Top Mounts a central role in driving stability: They have a significant influence on how safely a vehicle can be handled on the road and have a direct impact on steering behavior. We therefore recommend carrying out regular inspections. During a review from above with the hood open they should Top Mounts, but also the shock absorber be in perfect condition.

To determine the actual condition, you must the covers of the cathedral bearings be removed. If then Rust is visible, it is advisable to replace the dome bearings as quickly as possible with an improved set of accessories (for example from Sachs, BILSTEIN, MTS TECHNIK or Lemförder) to replace. Depending on the provider, such a set includes: thermowell, support bearings and one buffer. Such improved components contribute significantly to maximizing the technical life of the shock absorbers. This ensures optimal driving performance with safety and comfort.

If a shock absorber Oil loses, its functionality is reduced. A malfunctioning shock absorber can also affect the pressure stop.

Be careful with intensive use

The thermowell has an important function and should therefore be inspected particularly thoroughly. Caution is particularly advised when traveling frequently on unpaved roads. This is because minor damage to the sliding track of the piston rod can then occur very quickly. The result: the shock absorber becomes leaky. An improved strut bearing set provides a solution in this regard and almost every well-known manufacturer has accessories in their range that are tailored to the relevant vehicle.

As a rule, these are a good alternative, especially if the focus is on longevity. When purchasing, however, it is important to ensure that the damper is included in the accessories, if possible Teilegutachten and can therefore be installed without additional approval. That after assembly a Axis control and test drive of course, that goes without saying.
