Worn Diff and how to know what gearbox’s what?

[ekjdm14]

I'll have a look when I get a chance, got to move the engine/box in the next couple of days anyway. I imagine it could cause a thump if the diff bearings were that shot, although still amazed it's still got drive with the play being that bad! Another favourite for thumps on acceleration are the exhaust hitting somewhere along it's run so worth making sure it's aligned well and the rubbers aren't buggered.
