If your suspension starts making noises soon after replacing your
shocks, it would be a good idea to check for other worn out suspension
parts. New shocks will increase strain on other parts
of the suspension. Please don't assume the shocks are going bad
because they are the most recent suspension part you had installed.
Shocks and struts rarely fail in such a way as to make noise.
Squeaking noises are usually caused by swaybar or other bushings that are worn
or need lubrication. Clunking noises are almost always worn out bushings, upper
strut bearings or even swaybar end links.
99% of all shocks we submit to
Bilstein and Koni for noise issues are sent back because there is
nothing wrong with them.
| Condition |
|
Warranty Status |
|
Coating of film on shock body or piston rod. A completely normal occurrence,
not defective |
|
Normal condition, no replacement necessary. |
 |
| Signs of abuse, improper installation, broken or bent rods, collision damage
or modification. Also, shocks used for racing or in race cars. |
|
Warranty has been invalidated. |
|
| Unbroken piston rod is separated from shock body. |
|
Include note describing problem, return for evaluation. |
|
| Compression depth seems off--check by fully compressing shock and comparing
distance "x" to that of a new shock, same part number. If variance between old
and new shock exceeds 3/8" (10mm), old shock is defective. Exception: Strut
cartridges must compress to their internal bumpstop. |
|
Include note describing problem, return for evaluation. |
|
| Clicking noise, plus pronounced endplay--when piston rod is held downwards,
compressed halfway, then quickly moved up and down an inch or so in each
direction. |
|
Include note describing problem, return for evaluation. |
