Noise from Coilover? Help
2006 Mini Cooper S with 60,000 miles
I installed KW coilovers along with upper and lower control arms recently and now I'm hearing a mix of clinking and thudding noise coming from the rear left wheel well. I hear it every time I drive over small dips in the roads. I looked up some solutions but none of them have worked. I have changed the end links, checked the sway bar and bushings, checked if the shock was blown, checked if the spring was maxing out, checked the wheel, checked that all bolts in the area where torqued down properly. So far none of these have done anything to do with the noise. I have no idea what the noise is. Also, the car has been lowered about 3/4 of an inch. Can someone please help? Thankyou |
is the top mount tight enough?
is the spring pre loaded? is the spring collar secure? to rule out the sway bar 100% disconnect it and tie it up control arms tight? dampers not fouling trailing arm? |
Which control arms did you install? |
Check those rear end links really close for play (just a little amount makes a clunk noise), they like to wear out and clunk, mine need to be replaced after we did the Ohlins coilovers, strut mounts, rear mounts.

I tightened the top mount and that did not do anything.
The spring is not preloaded I also tied up the sway bar up and it wasn't it I tightened the control arms And the dampers don't hit the trailing arm I'm not sure about the spring collar though. How would that make the noise? |

Make sure the nuts are not loose also.

the spring should have some preload

Alta control arms top and bottom
https://altaperformance.com/i-160096...all-minis.html In my experience, this style of jointed control arm is noisy, just a nature of the design. While they will give excellent feel and control of the wheels, they will make noises that will increase as they wear in. |
^this too
|
mine did the same its the heim end jam nut, grease it up and give it a good tighten

above in post 5 you said it wasn't preloaded?
if the spring has no pre-load, as in wheel hanging and able to easily wobble/turn the spring, the spring in some conditions can shift causing noise, clunk especially. |
