Do you have a CLUNKING noise?

We get several phone calls, emails and PMs about customers experiencing clunking noises with different suspension setups. We wanted to help shed some light on the issue and help the community by posting this.

For reference I am running 19" wheels, KW Street Comfort coilovers and the car has 97k on the ticker. My E60 started making a clunking noise when I would turn the steering wheel or go in and out of driveways. Since I was installing new brakes from EBC I had my installer remove the coilover to inspect a few things including the top hat. The top mount was in decent shape about 25,000 miles ago when I had originally installed the coilovers. Now at 97,000 miles it is pretty beat up.

Left is old and right is new. The E60 and E46 share the same top mount.



Front Clunks:
Purchase new top mounts at the time of installing your aftermarket suspension. Regardless if your car has 30,000 or 200,000 miles. I was able to purchase new top mounts from PelicanParts.com for $28 each.



Rear Clunks:



If you have more questions please ask away and we will do our best to provide you an answer.

just put on HR touring kit, new control arms and FCABs. Also new brembo rotors and hawk hps pads in the front.. Now I have a cyclic thumping when I brake heavy to a stop. I do not feel it at speed or during normal driving.. any ideas?

Everything torqued correctly?

Yeah I went out this morning, went over all the fasteners, took the brakes apart again and checked and reseated everything.. Here is the good part.. took the car for a test ride, was still making the noise... was fed up so I beat on it a bit over some rough roads.. came to a stop, hey its not doing it anymore.. I did another 10 test stops and all is good. really don't like the "it went away on its own" .. maybe something just wasn't seated right?

Most springs/coilovers take some mileage before it settles. In your case it could have been a number of things including the brakes.
