Sannding pinion shaft
Some people sand down the pinion shaft so that the bearing can be pulled off by hand. Is this ok? It seems as if the shaft would turn inside the bearing causing it to wollow out after time.
For those who have done this, how loose do you get the bearing to fit the shaft?

Although I have not done it, I would argue that it could in fact be done without worrying about the pinion spinning inside the bearing, particularly if used with a solid pinion spacer. When used with a solid pinion spacer, the spacer shims are adjusted so that you can get the nut torqued to 140 ft lbs with the proper bearing preload. That 140 ft lbs of torque represents a hell of a lot of compression from the pinion head throught the inner race of the head bearing, through the pinion spacer, through the inner race of the yoke bearing, through the yoke and to the nut. Very, very low probability that the bearing race is going to spin on the pinion in that situation.
As far as welding the nut on and ditching the crush sleeve - if you do that any wear in of the bearings will result in lower than desired bearing preload and slop in the bearings = incorrect pinion contact with the ring gear and a very difficult time adjusting the preload (grind off weld, adjust, weld again).
I would recommend a solid spacer...

Some brands have a hell of alot of interference fit so it is ok to take a little off of the pinion but not enough so you can put it on and off by hand. Solid spacer is a good option but leave the welder alone.

Ok I left the welder alone. I did take my pinion to work and chucked it in the lathe and dressed it down with some sandpaper. I can put the bearing on and off by hand with some tension.
I talked to a guy local that is " the " man that sets up most rears around here and thats what he does as well.

The solid spacer replaces the crush sleeve. You can set your preload where you need to be and torque the pinion nut without worry. The solid spacer will not "give" under hard usage as a crush sleeve can sometimes.
Also if you need to replace your pinion seal later it makes it idiot proof, well almost!

I imagine it may help with a seal leak.
