Had a clunking noise from back of my 55 TD4, replaced all 3 diff mounts which were shot, replaced diff oil while I was down there, took it up the road for a spin and heard a new louder clunk from the rear.
Any ideas anyone?
I recently replaced the propshaft bearings so they're new as well.

The same sort of clunk? Diff mount tends to clunk just on acceleration or when you take your foot off the accelerator as the diff initially gets or looses power.

Different. The diff mounts was more of a low bang and a feel of pulling on acceleration.
This is quite a loud 'clunk', just from driving down my road to test it, so not going fast, didn't happen under acceleration or gear change just happened a couple of times at random. Checked everything underneath, took it out again and same thing.

Check the rear driveshaft CV joints for play and also the UJs on the prop.

Thanks, I'll check the CV's. UJ's were all replaced when I did the prop bearings.
