Front or rear? I previously had a clink from rear left and it was a broken spring
Had to replace a propshaft on Mk2 Escort I once owned in the Eighties. Under load it was fine but made a lot of noise when not under load and the vibrations were terrible as it was an ex Severn Trent Water Board van so it was like a drum on wheels. Happy days.

From a previous post about this:

"I had the same problem in my E60. It seems to be such a common problem with most recent BMWs that a solution is even listed on the Auto Data automotive information application used by a large number of indy mechanics.
The problem is as most are saying here - the input flange to the differential. Basically it connects the prop shaft to the differential. the splines develop play which give the "clunk sound you are all hearing upon pulling off / reversing or feathering the throttle in traffic or over speed bumps etc.
I have a mechanic friend who did the work for me. Its not a tough job, but it is time consuming and ideally you need a car lift to do the work comfortably.
The task involves the following;
1.) removal of all underbody covers
2.) removal of exhaust from after first muffler
3.) removal of aluminium heat shields
4.) removal of prop shaft
5.) removal of differential input flange (30mm socket required). Make sure you mark the nut clearly and count the number of turns as it has to go back to exactly the same position to retain diff balancing)
6.) apply Loctiti 660 retaining compound to the flange.
7.) put everything back the same way it was removed and wait a couple of hours for the compound to dry."
