Strut, Checking While Removed

Strut, checking while removed

Faulty struts are noticeable when driving due to loud rumbling noises - a result of wheel hopping - especially on poor stretches of road. Moreover, they can be recognized by a large loss of oil.

Note:
^ Struts are maintenance-free, shock absorber oil cannot be topped off.

A removed strut can be checked by hand as follows:

- Press strut together by hand.

^ Piston rods must move smoothly and with uniform difficulty over the entire range

- Release piston rods.

^ On struts with sufficient gas pressure, piston rods return to initial position by themselves.

Note:
^ If this is not the case, strut must be replaced. As long as there is no large loss of oil, the mode of operation corresponds to that of a conventional strut.
^ The damping function is also completely available without gas pressure, as long as there is no large loss of oil. However, noise may increase.
