Hi all,
I am experiencing a problem from one of the rear coilover. The coil over can get some knocking noise when the car is slow in an uneven raod or reversing from a hill with one rear wheel lands first to ground. When the car is in higher speed or "warm up" the knocking noise goes away or less frequently.
Obviously the problematic one has been repaired/rebuilt before with the out coming screw head at the bottom end of the coilover.
Is this a real problem to the coilver over ? or it just need a regass ? or the top pillow head need to be tighten up more ??
If it needs repair, can anyone suggest where I can send it to in Australia ??

I am appreciated of your inputs

Checked all your bushings?

What brand coilover? Teins are notorious for knocking.

Before removed the OEM suspension, the car was quite. Until when I installed these on.
It is a set of HKS hyper. The most noise is coming from one rear end only, the other end are fine.
To Tezz-Winnie: How shall I check the bushes ? Do you mean the bottom end of the coilover ?

:rolleyes: Go to a suspension shop and just get them to do a check over for you

Did you by any chance adjust your pre-load springs instead of your height? Remember that you should never touch the top rings when you're adjusting your height. Always the bottom ring.

Correct me if i'm wrong guys.
