A press help, although this guy managed just by heating/cooling.

This is a pretty good video going through carrier bearing preload. Don't pay attention to the numbers he's throwing out as yours will be different.

This is another good video to watch to get you familiar with the process.

Good luck!!!!

 

I hope you are very patient. A buddy of mine and I set up my front and rear in a day with the TT and Detroit and it went fairly smooth as he is not new to setting up gears. All was fine until an axle seal came loose and ended making its way down the axle and into the diff getting ground into a buttload of metal and rubber pieces. I attempted to rebuild myself and thought it had it 3 times but it howled like hell all three times. I was ready to chuck the thing in the lake and took it to a local rear end guy. $150 and 5 days later I was back in action. Wish I did that from the start! (and I have only paid someone else to work on my vehicles like 1 other time in my entire life)

 

And for the love of God order the yellow setup paint. It makes it WAY easier. The first time around we used the blue crap NAPA sells and its horrible, we ended up using white spray paint. LOL

 

I ran into some good luck here. One of my accounts is Kensington Motors. It's an Indy British and Mini shop here in town. Turns out they failed their fire inspection and I came in to the rescue and got him compliant. 3 new extinguishers 2 serviced one sprinkler inspection and some exit light batteries and he was good to go.
Now I'm gonna barter his services for my differential repair. New bearings and parts. Maybe he'll let me watch. Or even participate.
