[Cobra #3170]

Has anybody had experience in servicing the stub axle bearings and seal on a Jag differential? It looks like they use a crush sleeve and then use the nut to tighten the whole assembly until proper bearing preload is obtained. I need to have both stub axles shortened by about .150" to accommodate a Detroit Soft Lock carrier. I partially disassembled one stub shaft but the outer roller bearing seems to be held in place by a metal sleeve that is partially collapsed. Do I try and grab the bearing with a puller to remove it or grind the crush sleeve to get it off? I want to replace the seal, O ring, lock tab and the U-Joint drive bolts while it is apart, it seems that all those items are available but I am not sure what the set up process is. Thanks for any help.
