Noise right rear

[Pup X5]

Yes. I have searched the web and this forum.. Hate to start That way but there is always someone that has to spank others when they ask a question. Have found some threads. But nothing definitive.

The issue, accelerate lightly and let off the gas and clunk.. Very repeatable... Standing behind the car when doing this at idle speed, going forward A foot at a time, it is very noticeable especially on passenger side. Putting my hand on the trailer hitch I can feel it when it happens ....

We had it on the lift today checked what we thought we should and all nut bolt were tight.

I suspect worn bushing, but could not I'd anything...

We even too out the spare tire and Jack, nothing found.

Ideas? Help?

Thanks
