Welcome to CF!

It also takes over 150 lb/ft of torque to remove it. You'll need a long "cheater" pipe on your breaker bar and a large pipe wrench to hold the yoke. The nut is an interference fit on the thread.

Rebuilding a rear axle is not for the inexperienced unless you do a LOT of research and understand how critical the bearing preload and tooth alignment is. Once you do one, it's easy after that. It's MORE intense than rebuilding an automatic trans for the first time.

There are 2 bearings with a crush sleeve in there. To replace the rear bearing, the ring gear assembly has to come out. The bearing preload is 18 to 21 INCH POUNDS torque to turn JUST the pinion. You'll need about 200 FOOT POUNDS to start the crush sleeve, then a little less. As you take up the looseness in the bearings, stop and check the "torque-to-turn" of the pinion. Going too tight will require a new crush sleeve.

Remember It takes MEGA lb/ft of torque to turn the nut, but INCH POUNDS to turn just the pinion in it's bearings.
If you keep the original spacers behind the pinion inner bearing, your gear lash should be pretty close.
