I'm finally in the process of regearing the axles in my '86 CJ7. Got the standard Dana 30 front and AMC20 rear. So I set up the AMC20 using setup bearings, after playing around with shim stacks I got a nice pattern and now I'm going for the final install. With the new bearings, races and crush sleeve in place I went to crank down the pinion nut to set the preload and I can't for the life of me get the crush sleeve to crush. I built a custom metal lever that bolts to the yoke to hold it still and then I cranked on the pinion nut, at first I used a breaker bar, then a big breaker par, then a big breaker bar with a pipe on the end, then an even longer pipe. I'm at the point where I'm afraid threads will start stripping or sockets will start shattering.There is still about a 1/4" of in/out play in the pinion so I'm pretty sure it hasn't crushed at all. What do I do? Give the sleeve a little pre-crush? Eliminate the sleeve altogether and just install a solid machined sleeve of the appropriate thickness?
I'm at a loss here.
In better news I just noticed that the picture that appears to the left in everyone's post is pic of my jeep on a trail off of highway 4. Still waiting for my check.
