Shock Absorbers, Checking When Removed
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2018 Audi S6, 2018 Audi A6 Quattro, 2018 Audi A6, 2017 Audi S6, and 2017 Audi A6 Quattro. However, it is still accessible from the selected car via links, so may be relevant.
Defective shock absorbers 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:
Shock absorbers are maintenance-free, shock absorber oil cannot be topped off.
A removed shock absorber can be checked by hand as follows:
-- Press together shock absorber by hand.
- Piston rods must move smoothly and with uniform difficulty over the entire range
-- Release the piston rod.
- On shock absorbers with sufficient gas pressure, piston rods return to initial position by themselves.
NOTE:
If this is not the case, shock absorber must be replaced. As long as oil loss is not large, the effectiveness represents that of a conventional shock absorber.
The damping function is also completely available without gas pressure, as long as there is no large loss of oil. However, noise may increase.
