My tech friends tell me that it takes around foot-pounds to crush the sleeve. Since you aren't supposed to crush it too much, when replacing a seal since they don't want to open the diff and remove the ring gear for an otherwise external job they use foot-pounds on the pinion nut because they're pretty certain that WON'T crush the sleeve any more than it was originally.
I would be very uncomfortable about foot-pounds. That sounds way excessive, unless the crush sleeve they supply doesn't match factory specifications. There were two crush sleeves in the kit. One miked out slightly taller than the other, about. Nothing in the instructions as to which one to use. We used the tallest one the first time. Torqued the pinion down to max still have to check on the figure, might have been :oops: , checked the preload, reassembled, took it for a test drive, then the whine started when coasting after about five miles.
Came back, pulled the driveshaft, and that's when we discovered the up and down movement of the yoke. We also could feel a binding high spot when turning the pinion w. Also, one thing we did not do the first time was replace the pinion fore and aft bearing races, just the bearings.
So we tore it down, and the crush sleeve was barely crushed when comparing it to the new one. Reassembled with the old sleeve, replaced the pinion bearing races, and tightened the pinion nut just enough so it turned freely w.
Stuck in the carrier and axles; the previous high spot was gone, the pattern looked good, and it felt great and drove the same way. I wanted Dana-Spicer gears too, but got the Yukon 4. The Dana-Spicers were about double that w. I mis-read the original post.
I thought you were saying that you put foot-pounds on the used crush sleeve when you reassembled. No Eagle, you read it right; I probably wrote it wrong.
Pulled the pinion in and out a few times to see if the dayem crush sleeve would actually crush with varying torques, some all the way to ft lbs. It never did, as compared to the old one. On the final assembly we just tightened far enough until the preload was right. So far so good. Put another 60 miles or so on today, all seems well.
BTW, I'm just using regular dino Castrol 90 weight gear oil for breakin; plan to drain and replace with either Redline or Mobil 1 synthetic after about miles or so. Never have used syn gear oil before, okay to do? You can post now and register later. If you have an account, sign in now to post with your account. Paste as plain text instead.

Otherwise I have no clue. Never done a setup on one of those. Eagle Posted July 2, Be sure to let us know how long your pinion bearings last. FWIW I don't think it will be a problem so long as the bearing drag is in spec. It is after all just a piece of weak steel.
When I did the pinion seal in the D35 I just torqued it down to ft lbs and called it a day. Here's what the MJ FSM says for pinion setup: Tighten the pinion nut only enough to remove bearing end play using Tool J and a socket. Rotate the pinion when tightening the nut to seat the bearings evenly. Continue tightening the pinion nut to collapse the spacer and preload the bearings.

Couldn't find any discussion on this on the forum. Just installed a locker in my 14 bolt and pondered about reusing the ring gear bolts. I've read opinions on both sides. Any thoughts here? Seems to be a difficult item to find at the local parts store. Ron Dum Spiro Spero Moderator. This is a risk reward conversation to me.
Worst case scenario they fail. How much in parts do they eat up when they fail. How much use of your rig do you lose while its down. The failure is unlikely Berry Bad News. Joined Aug 10, Location Blacksburg, Va. I've had it go both ways for me!! When it went bad it locked front axle up ice cream coned the ring gear and broke carrier in half also while smashing my face on steering wheel! Went from 25mph to 0 real quick!

They usually come in a master rebuild kit I thought, which I get whenever I do a set of gears. Y'all are making sense
