- 2.7 Shock Absorbers
InformationWhen checking damping effect, care must be taken to select where to push or pull down to avoid damage or injury.
Method of Inspection1. Check for the presence of shock absorbers where these are a standard item.
2. Examine each shock absorber for damage, corrosion and security of attachment.
Note: For shock absorbers incorporated in MacPherson struts, inspect in conjunction with items under sub-section 2.5.
3. Examine each shock absorber for fluid leaks.
Note: Ensure that any fluid near the unit is from the shock absorber and not from another source.
Slight seepage causing a film of fluid on a shock absorber is not a reason for rejection.
4. Examine the condition of any linkages, pivots or rubber bushes.
5. At each corner of the vehicle, where practicable, push down or pull down from beneath and note the rebound of the body to determine if each shock absorber is producing a damping effect on the suspension
Reason for Rejection1.
a. No shock absorbers fitted to a vehicle on which they are known to be fitted as standard
b. a shock absorber missing.
a. External damage or corrosion to the casing of a shock absorber so that the unit does not function
b. an insecure or detached shock absorber.
3. A fluid leakage serious enough to indicate that the fluid seal of a shock absorber has failed.
4. An excessively worn shock absorber linkage, pivot or bush.
5. A shock absorber which has negligible damping effect.
