Strut or Shock Absorber Inspection
N0TE:lnspect the struts or shock absorber for
signs of oil
weepage or leaks. Make sure that the
oil is not from another source.
Weepage:
deposits a thin film of oil on the strut and spring
assembly or shock absorber.

on the strut and spring assembly or shock
absorber.

4800
- 8050 km. After this period no new signs
of oil should be visible.

to be installed.
Leakage:
covers the entire strut and spring assembly or
shock absorber with oil.

components.
requires new struts or shock absorbers to be
installed.
Strut or Shock Absorber Testing
N0TE:Struts or shock absorbers must be tested
in the vertical position.
I. Remove both strut and spring assemblies or
shock absorbers. The piston rods should extend.
Disassemble the strut and spring assemblies.
REFER to: Front Strut and Spring Assembly
(204-01 Front Suspension, Disassembly
and Assembly).
2. Compress the piston rods. Both piston rods
should offer the same resistance when
compressing.
3. Compress and release the piston rods. The
piston rods should extent equally.
