If the axles are out of the vehicle and sitting on a bench, you have all the time you ever wanted and the correct tools. It can be done. Under the Jeep with a Wallmart 20 piece tool kit and some drunk buddies helping on Sunday and you work on Monday.... Pass on that.
Their are a few specialized tools:
12-20 ton shop press
Bearing puller for Pinion so you dont ruin it taking it off 3 or 5 times to set pinion
Bearing preload adjuster (made mine)
Dial in/lb torque wrench
couple of cheap Chinese wrenches (these you toss when your pinion is not right and you need to disassemble AGAIN!!!!)
shim gauge set for the aussie install
4" angle grinder (to shave the 'ears' off the 8.25)
disk brakes off a +95 GC (might as well when the rear is all apart)
From what I was told don't buy the Master rebuild kit (like I did). Get the regular bearing kit and a full shim kit. I made my setup work with a mix of the 3 same size shims that came in my master kit and the old ones.
This job can be done and be successful if you are mechanically inclined, know the difference between ft/lb and in/lb, know the importance of measuring tolerance, .010 of one inch is very important. Don't just say "Baaaa its close enough.." Close enough can make loud expensive noises.
