When pulling away under heavy right foot there is a clunking noise from the rear right of my 3 door ,.I was convinced it was the dif.However today i had the car jacked up and when turning the off side rear(in the air) it would spin freely for about 4" then clunk!!
The near side was ok (no play).
I took the car out and gave it a thrashing and only when droping the clutch dose this hapen if driven normaly it is not evident.

would this be the drive shaft that is worn or something else .
All help appreciated
