It's one of the things I'll be getting checked Martin,it was a brand newshaft,fully balanced etc.
I'm suspecting pinion angle or possibly the rear UJ. While I had the shaft out to install my new rear 4-link one of the bearing cups came off along with some needle bearings,i'm wondering if I screwed up the refit.
The problem seems to have got progressively worse since then.

Whatever's happened it's spoiling my fun,I just wish it would stop biting me on the a..! grin
