Pinion shaft lock nut is still available as far as I can see. P/N 930.302.453.00 still shows up in dealer site part number lookup. You can reuse these nuts too. I've heard pros like Gary Fairbanks reuse these types of nuts all the time.

Take a good look at the ball bearings behind the retainer/tensioning plate that secures the stack to the diff housing. Those are the ones that seem to get beat up the most. Often times you can clearly see if they're badly worn on the small-ish outer races that the balls ride on.

I stole this picture from California Motorsports ( and it's a bit extreme but still shows what i'm referring to. The badly pitted "collar" is the outer race that rides against the balls contained in the brass cage. I would replace a bearing that shows a lot of graying & a bit of texture on the outer races.
