Loud clunking sound over bumps

[Rom]

Hi all,

My 99 2.5L is making some weird loud clunking sounds over bumps, which sounds like the rear passenger side. I’ve lifted the car and inspected everything, tried moving the wheel up and down, checked for any loose suspension bolts, but nothing apparent.

I know the control/caster arm bushing sometimes wears right under where the passenger door ends and causes weird noises, but the sound does seem to be coming from much further back. Driving on a smooth road is quiet - just any bump clunks loudly. Handling does not appear to be compromised at all.

The car does have PSS9 coil overs and Tarett drop links, as well as adjustable toe control arms, but all that has been checked and appears tight (at first I thought the suspension top mount had come loose).

Anyway, any other ideas as to what it could be? I thought maybe the anti roll bar bushings, but they seem okay. I might disconnect the drop links and drive around to see if it changes.

Any ideas appreciated!

Thanks!

S.
