Today I had some time to check the pinion bearing and the u-joint on the stub shaft.

Started with the pinion bearing - looked ok - no metal in the oil and no play.

Moved over to the rear u-joint ....
Removed the cover and found that one bolt had gone loose and made the noise !!

Some pics of the culprit and the damage it has caused !!

No wonder we had noise !

The front u-joint looks ok so now we just have to find a new and replace the broken one.

Hope to find one in Sweden else I have to order from the US - any good source in the US for this part ?

Thanks all for your input!
