And I apologize for beating a dead horse on gear install, I’ve done this many times before on other trucks, but like I’ve searched, I’ve either reused gears and swapped to a different style carrier, or kept the carrier and swapped gears. Not many swapping gears and carriers at the same time. It’s basically starting from scratch at this point.

Do you have the earlier 10.25 or the later one with the extended pinion area? Ford had a problem with the splines wearing on the pinion yoke, and it will start rocking on the splines and it works the pinion nut loose. Mine does it, I just tightened it back up for the 2nd time the other day. I am not sure what year they did it, but they made the splined area longer and along with that the nose of the pumpkin is longer to help get rid of this problem. So I would check this area on yours if you have the earlier style ( mine is a 1989) and if there is any wear between the yoke for the driveshaft and the pinion splines, possibly a new yoke would help it for awhile.

The crush sleeve is just a way they can set the bearing preload on the assembly line really fast. The do not want to be fiddling with shims, they have to get the axles out the door(the axles are usually made at a axle plant somewhere else). If you want to use the shim kit, you can. The problem with the crush sleeves, they can be very difficult to crush if you get a new one. It takes a lot of force to crush them correctly. I never had any problem just tightening up the old crush sleeve, whether it's just to tighten the nut or to replace the seal for a oil leak.

The other thing with the crush sleeve is if putting a heavy or shock load on the R&P like drag racing or off roading and bouncing the shock on the crush makes it crush more and then no more pre-load.
BTW I use a crush sleeve in my drag car but I would never hear if the rear is making noise over the open headers!

Not sure if I’m doing pinion preload properly with this crush sleeve, I set it up using the filed out bearings, replicated the old shim pack just for kicks and used the crush sleeve eliminator with no shims, the old nut and driveshaft yoke. I cranked it down good and tight and got 15-20 inch pounds preload. No way I got it right the first time?
obviously it has to come apart a few more times to check the wear pattern on the ring gear and adjust the pinion shims, but is that really all there is to the crush sleeve eliminator?
