How do you take the rear yoke off?

Crush sleeve sets the preload of the pinion bearing. You can tighten that nut until the bearing case breaks so they give you a piece of thin wall pipe as a spacer between the bearing and the nut. When you approach the torque spec, (like 145 ft/lbs) the sleeve will start to deform and crushx setting the proper preload on the bearing. Other models used shims that needed to be stacked so the preload would be correct when the nut torque was correct, a juggling match as you had to do it a few times to get it correct. The sleeve is a one and done part. Set it and forget it bit tour supposed to replace it every time you break the nut torque. Just leave it in and work the broken stud while its on the pinion. That piece should not be in tight as the torque is gone with no head. May get lucky and have it walk itself out using a reverse drill bit.
