2005 E53 Clunk from rear end??

[Purplefade]

I know this isn’t rear diff related but mine did nearly the same thing as yours and I diagnosed it to the bridge seal and 4 pickup tubes on the mechatronic unit.

I thought rear diff, failing guibo, bad bushings all that and actually threw some money at it before I had a BMW mechanic from work ride in it totally by accident and say “wow you’ve really got some slop in the valve body”. On that I went down another rabbit hole of research and $36 in parts later had it fixed.

Just food for thought, good luck!

I will add that I also noticed mine ever so slightly when accelerating away from a stop light. Mine was more of a dry thud vs metal on metal sound FWIW.

Thanks - it helps us figure what relates to our own cars and what's not relevant.

Totally good call!! That thought went through my mind as I was responding, I know he said 3.0 and without thinking I jumped right in

I should probably add the to my profile as well...

I have had a clunk from the back of my X5 for quite a while. I'm pretty sure it's either subframe bushing or one of the myriad ball joints back there. I can reproduce the thud going slowly over a speed bump 100%. Wife's X5 doesn't make the thud.
