Powetrax lock right issues

Aaah! Thanks guys. Looks like i clicked on the wrong item when i bought it! wasn't looking for something quite so agricultural.
Besides the clacking going 'round corners, is it normal to have a bit of a bang as i hit the gas as i straighten out?
Goes fine in a straight line and chirps the tyres thru gear changes without effort.

This is my first experience with an lsd/locker of any kind so any advice/commentary appreciated as ever.
