Checking the rear shock absorber (VW Transporter T4)

The shock absorber can be checked by hand.

1. Remove the shock absorber.

2. Hold the shock absorber in a vertical position. Stretch and compress the shock absorber.

3. The shock absorber should move evenly and smoothly with the same force.

4. A faulty shock absorber can also be identified while driving by knocks and cracks. Of course, these noises can have other causes, such as loose screws, nuts, faulty wheel bearings, articulated synchronizers. Therefore, before replacing, it is necessary to check the shock absorber and, if necessary, give it to a bench test.

5. If the shock absorber is working perfectly, small traces of shock absorber oil are not a reason to replace the shock absorber. The main rule: if traces of oil are visible, which do not spread further than from the shock absorber cover (piston rod sealing pin) to the lower spring support, the shock absorber is in good condition. Provided also that the oil stain is matte or dried from dust. A small oil leak can even be considered an advantage, since the sealing pin is lubricated and its service life is thereby increased.

6. If there is a strong oil leak, replace the shock absorber. Shock absorber oil is not added.
