Checking shock absorber on shock tester — AUDI

A shock tester (shock absorber tester) enables shock absorbers to be checked without removing them. The damping effect can be assessed on the basis of the pointer deflection/printout.

Special tools and workshop equipment required

Boge shock tester

Or

Sachs shock tester V.A.G 1975

Or

Maha shock absorber tester VAS 1990

Test requirements:

Temperature +10 ... +40 ° C
Driver in vehicle
Inflation pressure OK
Vehicle standing centrally aligned and straight on wheel contact plates
Front wheels straight ahead
Handbrake not applied; foot brake not pressed

Limit values

The condition of the shock absorber can only be assessed as follows:

Adequate damping effect

Or

Inadequate damping effect

Notes:

Intermediate readings for reduced damping performance are not possible.
Service life forecasts are not permitted.
Measured values which include the influence of the spring travel end stops will be biased.

The following values only apply to the above-mentioned test benches. If the stated values are exceeded, less than 50% of shock absorber performance is being obtained and replacement is justified.
