Rear end clunking

Rear end making a clunking noise over slow bumps. SR springs and Koni yellows and BMR adjustable panhard on the car. Another guy had a similar noise and said it was the panhard. I just checked the panhard bar and it's fine also the rear strut bar. All seems tight. What else would cause the clunking? Thanks

My 14 is stock and it creaks over bumps especially over turns combined with bumps I don't know that I would call it clunking... But maybe... But initially it scared me but I think it has something to do with the unibody chassis. Have a buddy with a 12 5.0 and does the exact same thing. All the ones I've been in make weird noises over bumps. Not sure if this alleviated your concern.

Rear end clunking

I had the same ISSUE with my car. SR panhard bar here. That needed to be tightened up, and the NVH went away. Once you change out suspension components, it's only natural you're gunna hear some minor clunks and squeaks.

Get under there, and check everything out. Make sure EVERYTHING is tightened.

So I guess it's normal then. Weird. Thankfully the exhaust kind of hides the sounds. Thanks

there are some threads on here mentioning the two piece driveshafts are the cause. those who have upgraded to a one piece mentioned the clunk was gone.

It could be, but then again maybe not. And upgrading to a one piece DS is costly and involved. Would be a shame to shell out that kind of coin, and still have said NVH. I tend to think it's the P bar because I experienced the SAME EXACT thing. Adjust that bad boy, and tighten it up. Is the noise unbearable? I no longer have the clunks, but a few squeaks here and there. It's all manageable.

I had the same problem a while back. The clunking noise was driving me nuts. I heard the noise mostly when going slow over speedbump's. It sounded like something was loose in the trunk bumping around. Turns out it was my adjustable BMR upper control arm was loose.
