So...I'm installing a Dr. Diff rear diff and 3.55 gears in my 741 case and I'm having a hell of a time with this pinion. Getting the depth and preload set has been a real PITA as it's the first time I'm doing this, but that's not really my problem. The problem is constantly having to tighten and remove the pinion nut is absolutely destroying the threads on the end of the pinion. Is this normal? I know these nuts are tighter at the end so they have some sort of locking tension it's to the point where I'm not comfortable continuing.
With that being said, I've tried a thread chaser which helped, but it's still not very optimal. I have a extra set of 3.73's here that I tried the nut on and I can hand thread it to about 1/8 of the end of the nut. On the bad one I can't get it any closer than about 1/2" by hand. Are re-tapping these threads viable or would that remove too much material to let the nut "lock" properly? Or should I start with a new ring and pinion again and buy a castle style nut with no taper to do the test fitting?
Any tips are appreciated...
