No clonking slight one when u go forward and back then brake? But vibration is only on very low speed when pulling away turning not all the time but fairly often
Sign of healthy diff, also the clonk you get going backwards is just slightly undersized brake pad in calliper, have you aftermarket pads ?
So nothing to worry about then? No brembo ones atm will be changing to aftermarket near future something better of course. Gearbox on these slightly clunky letting of accelerating or selecting gear? Not a load clunk but can hear everything?
