STRUT AND SHOCK ABSORBER INSPECTION
NOTE: The shock absorber assembly DOES NOT have to be removed from
the vehicle
to perform the following inspection procedure.
NOTE: A light film of oil on the top portion of the lower shock
absorber tube is normal.
DO NOT replace the shock absorber for this condition.
Fig. 10: Identifying Shock Absorber Conditions
Condition 1
Oil or fluid residue only on the bottom or top of the shock absorber and not
originating from the shaft seal, is
not a shock absorber related problem. DO NOT replace the shock absorber, look
for other external leaks.
Condition 2
Light film/residue on approximately 1/3 (a) or less of the lower shock tube
(A) and originating from the shaft
seal, is a NORMAL condition. DO NOT replace the shock absorber.
Condition 3
Oil drip or trail down the lower shock tube and originating from the shaft
seal, is an ABNORMAL condition.
Replace the shock absorber.
Condition 4
An extreme wet film of oil covering more than 1/3 (b) of the lower shock tube
and originating from the shaft
seal (B), is an ABNORMAL condition. Replace the shock absorber. Refer to Shock
Absorber Replacement.
Inspection
- Verify the customer's concern is present. If the concern is present,
continue to the next step. If the concern
is not present, then the vehicle is operating normally.
NOTE: The shock absorber assembly DOES NOT have to be removed from
the
vehicle to perform the following inspection procedure.
- Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle
.
- Visually inspect each of the shock absorbers for external fluid leaks.
Refer to the following conditions 1,
2 , 3 , and 4 for visual inspection.
- If conditions 1 or 2 are found, continue to step 4.
- If conditions 3 or 4 are found, replace shock absorber. Refer to Shock
Absorber Replacement
- If equipped with electronic suspension control system, ensure that the
system is working properly. Refer
to Diagnostic Starting Point - Electronic Suspension Control.
- Use your hands in order to lift up and push down on each corner of the
vehicle 3 times. Remove your
hands from the vehicle. If the corner motion exceeds 2 cycles, replace the
shock absorber. If the shock
absorber does not exceed 2 cycles, NO repair is necessary.

SHOCK ABSORBER DISPOSAL
Fig. 12: Drilling Hole In Shock Absorber At Centerpunched Locations
WARNING: Gas charged shock absorbers contain high pressure gas. Do
not
remove the snap ring from inside the top of the tube. If the snap ring
is removed, the contents of the shock absorber will come out with
extreme force which may result in personal injury.
WARNING: To prevent personal injury, wear safety glasses when
centerpunching and drilling the shock absorber. Use care not to
puncture the shock absorber tube with the centerpunch.
- Make an indentation 10 mm (0.4 in) from the bottom (4) of the tube (3)
using a centerpunch.
- Clamp the shock absorber in a vise horizontally with the shock absorber
rod (1) completely extended.
- Drill a hole in the shock absorber at the centerpunch (4) using a 5 mm
(3/16 in) drill bit. Gas or a gas/oil
mixture will exhaust when the drill bit penetrates the shock absorber. Use
shop towels in order to contain
the escaping oil.
- Make an indentation in the middle (2) of the tube (3) with a centerpunch.
- Drill a second hole in the shock absorber at the centerpunch (2) using a
5 mm (3/16 in) drill bit. Oil will
exhaust when the drill bit penetrates the shock absorber. Use shop towels in
order to contain the escaping
oil.
- Remove the shock absorber from the vise. Hold the shock absorber over a
drain pan horizontally with the
holes down. Move the rod (1) in and out of the tube (3) to completely drain
the oil from the shock
absorber.
