84 cj 7 258ci amc 20 moser 1 piece axles dana 30 front dana 20 transfer case 3 spd tranny
im having a problem with driver side axle burning up bearings ground down the spacer so bearing sticks out .30 still not helping 84 cj AMC20
 
What spacer? Mine just have the bearing and shrink sleeve. Also what is .30? If that is thousands of and inch then .30 is 3/10's which is a whole lot. Those bearings are balls and do not want any preload. They should be basically floating.
 
its 30 thousands the spacer came with the bearing kit from moser it had one in it before there tapered bearings

The .030 sounds right, at least for my superior axles.(IIRC)
The only thing I can think of would be a bent tube or the lack of packing the bearing with good grease. (which I hope you did).
How long did the first bearing last?

I'm voting on your tube being bent but if you do take that one out the best swap would be a ford 9" rear. They are super tough but will require tube cutting and new shafts to fit.
