I would try the old one first. If you are using the original brgs. there is bound to be a little wear on them & the sleeve will crush enough to get the necessary preload. If the pinion nut doesn't have any drag on it get a new one. This is a self locking nut & will back off if there is not enough drag.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
