I only use spacers. You can buy them for about $40 and they take the place of the crush sleeve. You get a solid spacer and a shimming kit. You shim so you get the proper bearing preload and they never back off. It makes putting the pinion nut on easy. I just use the impact and draw it up tight.
If down the road you need to change a pinion seal it is quick and easy to remove the yoke, change the seal and using and impact put the yoke back on.
Also if you run into problems with a yoke that tends to leak there are nice little slip on sleeves that go over the yoke and provide a little better fit for the pinion seal, plus a little tighter fit.
If you want to read a paper on setting up a rearend this guy Gary is really good at it. This is setting up a corvette rearend but the principle is all the same.
Setting up the side gears/posi shimming is usually not well known and really affects endplay on the axles plus prevents chattering on the corners.
Gary also provides the solid crush sleeves and the tiny sleeves that slide over the yoke to provide a much improved pinion seal surface.
Polishing a yoke with fine emery paper is not enough
