Regarding the notchy diff, the manual says to fully tighten the diff then back it off, but don't do this - as for me it dented the diff plates with the balls and went notchy. Turn the plates over and try again!

I tighten and check for it slipping once in the car - both of my diffs have been fine at the first meeting like this, infact - they don't slip atall, I reckon I'll pull a tyre off before the diff slips. LOL.
