DISCUSSION:
This Information Only TSB is to communicate the criteria for shock and strut diagnosing and replacement. If it
is determined that a shock or strut is defective and needs to be replaced, only replace the defective shock or
strut as required.
NOTE: Do not replace any other shocks or struts because one is defective.
It is recommended to perform the following before any shock or strut replacement:
● Refer to the detailed procedures available in DealerCONNECT > Service Library> under: 02 - Front
Suspension / Front / Diagnosis and Testing OR 17 - Rear Suspension / Diagnosis and Testing.
● Each shock or strut should be diagnosed separately.

Explanation of why shocks/struts mist or appear wet:
● The reasons why misting occurs is usually evaporation of shock fluid from the rod under heated conditions.
The evaporated fluid condenses and forms a mist on the shock body and cover. This is normal because
a certain amount of shock oil must stay on the rod to lubricate it. Excessive runs and drips are something
different and it is likely caused by damage to the rod or sealing system. Misting is most likely to be noticed
at higher mileages due to accumulation.
● Some misting accumulation is normal and does not degrade ride performance.
NOTE: Do not replace components for normal oil evaporation (misting). Continue to monitor these
components.
After any shock/strut replacement, it is important to note the performance of a new shock or strut changes
over time and normalizes after a breaking in period of approximately 160 km (100 mi). The difference in
performance between the left hand and right-hand sides, if it is noticed, will be quickly balanced out during this
break in period.
