I'm trying to diagnose a clunking sound and trying to rule out the springs. Local install shop thought it may be that because the top coils sit to the point of touching. They applied silicon grease to the top coils and it does help. Haven't heard a clunk during morning drives (when the components are cool) but the clunk comes back later on the day.

Anyway, have a look at the following pics and if you can tell me how your springs are sitting. I also currently have the perch set high with 3.5 cm (about 2 finger gaps) between the tire and fender edge. Would lowering the perch change the loading on the springs?

I am having clunking too, not sure if its the KW's or the Neu rear sway ?

It could be that its not the KWs, but something else like my front sways, tie rods, bushings, control arms, etc. Greasing the spring coils though seems to help so its pointing somewhere in that location.

Basically trying to rule out possibilities for the moment. The local shop took the whole thing apart and reinstalled, making sure everything was tight, so I'm investing if something is rubbing or with the height changes, a component is out of spec.

I may have to get myself a mechanics stethoscope to further diagnose where the noise is originating. A rod of wood would probably suffice if I can get it in and around the tight spaces.

My situation is tricky - doesn't happen without load on the tires so can't jack the car up. Doesn't happen in a straight line so bouncing the front end doesn't produce anything. Only happens when turning at low speeds.

if i move the steering wheel back and forth it is coming from the top of the suspension on the drivers side. Also makes a noise a lock sometimes.

I have a V2 setup and paint is missing from the spring from rubbing.

same here.

You'll need to remove the entire coilover from the car and check the nut. Sounds like there's a small gap between the seat on the piston where the washer sits and the control arm assembly. Others have reported the some sound. I was careful to ensure I had everything here tight when I installed mine. It's easy to thing you've got tight, when in fact you don't.

The nut that holds the upper perch and strut bushing on is most likely loose.

Then you can test this by inserting cardboard pieces between the springs. Simpley raise the car off the ground, insert some cardboard between the coils and go drive. If the noise is severly diminshed then it's spring bind. Only remedy is for the company to redesign the spring.

A work around is to slip vinyl tubing on the coil of the spring. This requires complete removal of the spring, and actually is somewhat common.

as can be. I'm tending to believe him because the sound is not happening during my morning drive to work.
