Thanks for the quick response, I used the diff that came with the M05 Pro kit (ball diff i think) but did not use any loctite - ill check that.
Update - Pulled the motor out and when i first installed the pinion gear i hadnt used the 'pinion stopper', used it moved pinion gear further out and car is happy again.

I would also check the pinion has not moved on the motor shaft.
