I don't believe in crush sleeves. They have a habit of backing off and they are also hard to get the correct bearing drag. I prefer a spacer similiar to that used in the axles. They are available over the counter with a shim kit for easy adjustment.
I made my solid spacer from a solid piece of steel or a heavy walled pipe, whatever is available. I make them ,010 longer then the original crush sleeve I take out and find tune them later.
I install the longer spacer with the new gear setup then using the old pinion nut and the impact tighten it up, measure the end play and take the spacer out and cut it shorter by the amount of play. I am aiming at 000 play which give me a very slight drag.
While this sound complicated it is easy if you have access to a lathe.
I drill a hole through the spacer a little larger then the pinion shaft, I turn one end slight larger ID then the bearing ID and the OD slight smaller. I do the same for the small end.
I have used about 6 or 8 of these with never a problem and my impact can do the work, I just tighten a new pinion nut with green loctite for the final assembly as tight as the impact will go.
They never back off and the bearing preload is easy to set.
Hope the pictures work.
