Should my tintop shock be hissing?
speedyxjs - 13/6/10 at 07:33 PM

Over the past few months i have been experiensing a very faint knocking from the osr on the tintop when goin over bumps (even small ones), that has been slowly getting worse (more frequent rather than louder). I originally put it down to the exhaust hitting something as it used to disappear when the car warmed up.

As it is now doing it all the time, i have just been out to look at the exhaust but it is all fine. What i have noticed is that the osr shock is making a hissing sound when i bounce that corner and i can also hear a faint knocking. The thing is that the rear shocks were only replaced a year ago and have only done about 7k since. Surely the shock cant have gone in such a small amount of time?

New damper required.

Hissing? Is it more of a squelching as the oil flows through the damper?

Are you sure you dont have a dodgy bush somewhere? (or loose top mounts!)

It is more of a hissing. Definately not a squelching. It sounds like a bike pump.

Gas shocks can hiss when compressing

But would one side and the other be silent?

Depends if you have a oil one on the other side! Most shock manufacturers sell both types for the same car.

Sometimes the rubber boots (if fitted) can hiss as air enters & exits, which is normal. A noisy shock will normally leak

The hiss isn't the main symptom to consider it is the click ---- if the bushes are OK and tight then any clicks or clunks usually indicate and internal problem in the damper. If you then consider the hiss/squelch noise only coming from that particular damper it points pretty conclusively to a failed damper.

Thanks for the help guys. Iv been to the garage that did the work and they have said it is still covered by warrenty (was fitted last July) so should get it sorted for free

hissing? 's normal if it is an AC Cobra or Dodge Viper.
