Message: [QUOTE="Tree Trimmer, post: 1466800, member: 716"] yes, they use a crush sleeve. if your going to do it, new bearings, races, and crush sleeve. slide axle shafts out a bit. drop out carrier, replace inner and outer pinion bearings and races. put new crush sleeve in, new nut, and tighten it down to I think it was something like 25-35 in/lb of drag, which is a fk load of torque, if your looking for that spec. well into the high hundreds of pounds. we just cranked up the line pressure on the impact to like 175 or something and still almost didn't get it. depending on your situation, you might need to slide the axles back in, push on the brakes, and put a very long cheater bar on a 3/4 breaker bar. note i said very long cheater bar. if you need to do it that way, you will be surprised just how fking tight it actually is to get to the required drag. make sure you slide the axles back out of the carrier before you do your drag check. the spec is for just the pinion and the carrier, not pinion, carrier and axles etc. when you get your in/lb of drag, take a hammer and punch, I used a 3/4 piece of round stock so as not to fk something up and crack both the yoke and the inside of the rear end on the pinion shaft and recheck your in/lb of drag. repeat that last step over and over till you don't get a change in the drag. you will beat the new races in, they will feel totally seated, but they wont be. you preload that race, and crack it, it will seat more. i think when we did mine we ended up tightening and cracking it like 5 or 6 times before we didn't get a change in drag. On new bearing and races, try to shy towards the higher end of the drag, if your reusing bearings or races, stay towards the middle of the drag. this would also be a good time to put in a tru-trac if your haven't already, and for chits and giggles, replace your carrier bearings. just make sure to NOT get the koso bearings. get good old timken bearings, or don't bother. randy's ring and pinion is where i got all mine from. They have a complete kit, if you go that far. or pieces of a kit. [/QUOTE]
