ring and pinion stripping

[phildogg]

Hey running a raze st and the stock ring and pinion are stripping,alot of clicking when braking and occasionally under hard acceleration. the rear is rough to the feel.tried to shim it but I think the damage is already done. I was wondering if another ring and pinion out of something like a hyper 7 would work or just go back with stock ring and pinion.lmk
