This bulletin is being revised to add the 2010 model year and Inspection Procedures. Please discard Corporate Bulletin Number 05-03-08-002B (Section
03 - Suspension).
This bulletin is intended to help identify the severity of shock absorber and strut fluid seepage. Improper diagnosis may lead to components being
replaced that are within the manufacturer's specification. Shock absorbers and strut assemblies are fluid-filled components and will normally exhibit
some seepage. Seepage is defined as oil film or dust accumulation on the exterior of the shock housing. Shock absorbers and struts are not to be replaced
under warranty for seepage. Use the following information to determine if the condition is normal acceptable seepage or a defective component.
Important
Electronically controlled shock absorbers (MR) may have a tendency to attract dust to this oil film. Often this film and dust can be wiped off
and will not return until similar mileage is accumulated again.
Inspection Procedure
Note
The shock absorber or strut assembly DOES NOT have to be removed from the vehicle to perform the following inspection procedure.
Use the following descriptions and graphics to determine the serviceability of the component.
Shock Absorbers
Do Not Replace shock absorbers displaying condition 1 or 2 levels of seepage.
1. Oil or fluid residue only on the bottom or top of the shock absorber and not originating from the shaft seal (the upper part of the lower shock tube).
2. Light film/residue on approximately 1/3 (a) or less of the lower shock tube (A) and originating from the shaft seal.
Replace shock absorbers displaying conditions 3 and 4 levels of leaks.
3. Oil drip or trail down the lower shock tube and originating from the shaft seal.
4. An extreme wet film of oil covering more than 1/3 (b) of the lower shock tube and originating from the shaft seal.
