clunk in rear when going over bumps

[dcramer]

I suspect this is a control arm bushing but wondering if anyone has any other ideas.

I thought it was the muffler, as it happens in corners, but I'm pretty sure it's not. I hear it when I back out of my driveway over the little lip between the road and driveway, mostly when I am on an angle to the bump. Or going around corners.

There's nothing obviously loose. The normal places have been checked. RTAB, and the shock mounts are good.

Anyone ?
