I need a new pinion yoke for my 10.25" rear.

My truck has a vibration that has been bothering me at highway speeds. I am ordering a new carrier bearing just to eliminate the possibility of that adding to the issue. The real crux of the problem is the pinion yoke. the ujoint moves side to side within the yoke to the tune of about a sixteenth of an inch or better. The yoke itself has come loose before and my trans rebuilder tightened it and noted the worn yoke.

Can this be done without removing the axles, carrier and such? I have read that there is a crush sleeve eliminator but don't know if that saves any work. I haven't gotten into tearing rear axles apart aside from a 9" Ford about 17 years ago now. Is this a day job with simple tools or should I have a garage that's versed in differential work do this for me? I am familiar with bearing preload and the ring and pinion meshing correctly but am kind of out of tune as to whether I should order parts and tackle this myself. Should I find a long yoke rear and work with that at this point?

What I have found it when the yoke gets loose, tightening it or replacing is only a temp fix, the yoke will wear the pinion splines and never be an almost press fit, and to do it properly I'd pull everything out and get a new crush sleeve or better yet as you stated crush sleeve eliminator kit and set it up from there. You would probably be better off getting the long pinion gear set and yoke and going from there.

You'll need an inch pound torque wrench that's low 0-30 ish in/lbs, dial indicator and some time and patience for a gear change (I'd pull the axle to make it way easier to work on, but that's me) be prepared for around a weekend time frame for gear change and incase of issues or parts runs.

All in all its up to you if you want a shop to do it or if you'd like to do it, probably looking around several hundred at the shop for just labour then parts on top of it, maybe a good used axle from a 93 and up truck would be a better option as they had the better pinion and yoke combo.

The newer long pinion 10.25's seem to be plentiful, especially the 4.10's. I am just finishing up the swap in my 86 to a 94 long pinion diff., pretty easy job to do. With the research I did it seemed like the best long term fix to go with the long pinion. So far the only real change is the rear conversion U-joint 1330x1350 spicer 648 and going from U-joint U-bolts on the short pinion to a Strap kit on the long pinion. Might be a perfect chance to roll a 3.55 TracLoc under your truck. I paid $180 for a complete 94 4.10 TracLoc Diff. and then decided to go 3.55 and bought the 94 3.55 TracLoc Diff. complete with springs and overloads for $200. I had a shop quote me about $300 or about 5 hours to do the swap. In the long run it would be the best long term fix, you could slap another yoke on your current setup and just count the threads and set the nut to where it was, but the problem will come back from what I have read.

You can get a long yoke diff but remember that those have a smaller pinion bearing so don't just get a R&P and try to swap it in. Better to get the whole diff IMHO.

One ear of the yoke you have...will shall I say most likely be worn. HA HA..in a temp situation what one could do..is hammer the small tab over a bit pointing in to the cap...this essentially eliminates all vibration...or at least it did for me! LOL

I knew I had to replace the diff and have one to go in so it's a win win..fix it short term HAMMER plan...while long term repair is being all rebuilt in prep of install.

Oh an for what it's worth, I would say get a diff shop to set up a gear set and CSEK cause sometimes they are a *****.

My yoke was loose for a while, it slid right off, the new one went on tight so my splines were ok. It has hot come loose again, liberal red loctite was used on the nut. I have crush sleeve eliminatior kits in the desk for the time when it comes apart to machine the carrier for the tone ring.
So I guess it is up to you weather or not you wnrt to install a new yoke, I would try it first. a tiny bit more preload wont hurt anything. JM2C.
