I had some play in the forward differential yoke after losing the carrier bearing, for the second time. Behind that Yoke is a one time use crush nut. Seems the old one was being reused. I bought a new one at FleetPride for $25 and had my local shop install it as it is supposed to be torqued down to so many hundred foot pounds. They had the wrench. Took him a few minutes and problem solved, that little bit of play went away in the yoke. No more vibration and carrier bearing is fine.

I know nothing about big trucks, but would the crush nut your talking about be the same thing as a crush sleeve on a Ford 9 inch?

Boy, I don't know. On your front diff, remove the yoke, and there will be a large nut that slips over the input shaft, which keeps the bearings tight and the shaft from wiggling around that the yoke slips over. I was having a problem with vibrations and losing the carrier bearing. I was having the truck serviced at the local TA and the mechanic there discovered my new carrier bearing was toast due the wobbly yoke and worn crush nut not doing its job of securing the bearing. He did not have the crush nut on hand, so I had him install the new carrier and the following day I went and had that nut replaced. That was well over a year ago and I have not had any issues since.

The nut itself is large enough to slip over the shaft, and it is about 3/8 to 1/4 inch thick maybe give or take. It sure didn't look like much, not $25 much.
