Checking the removed shock absorber

Install the shock absorber in a vertical position

Check the condition of the shock absorber by moving the piston by the rod along the entire stroke length.

If jamming or lack of resistance is detected throughout the entire piston stroke, and obvious traces of fluid leakage through the oil seal are visible, replace the shock absorber.

- Cause of malfunction


Fluid leakage from shock absorber:

- Loosening the reservoir nut

Tighten the nut

- Rod seal wear

Replace the oil seal

- Nicks or marks on the rod, wear of the rod until the chrome layer comes off

Replace the rod

The absence of a chrome layer is checked by the redness of the rod when wetting it with a solution of copper sulfate

Look at the article - “Gazelle shock absorber

Unsatisfactory performance of the shock absorber (frequent breakdowns, car rocking):

- Insufficient amount of fluid in the shock absorber

Remove the shock absorber from the car, disassemble it, replace faulty parts and add fluid

Insufficient force during the recoil stroke (when stretching the shock absorber):

- Piston bushing wear

Replace the bushing

- Nadirs on the piston or cylinder

Replace damaged parts

- Leaky overlap of the bypass valve

Disassemble and wash the shock absorber. If necessary, replace the valve and its parts

Insufficient force (or “failures”) during the compression stroke:

- Loose closure of the compression valve due to foreign particles

Wash the shock absorber parts, fill with fresh fluid

Knocks and squeaks when the shock absorber operates:

- Looseness or wear of the bushings of the upper and lower shock absorber lugs

Tighten loose nuts. Replace damaged bushings

- Excessive amount of fluid in shock absorber

Pour liquid into the shock absorber in a strictly defined amount

- Self-loosening the recoil valve mounting nut

Tighten the nut
