you're better off having it done, the bearings need to be shimmed so the contact with the race is set up correctly, the aluminium casings shrink and expand with temperature and to set it up properly you'll have the spread the case a bit.

I just had my 82 diff rebuilt with all new seals, bearings and gears and I took it to a qualified mechanic to have it done. Everybody tells me they are a real PITA to do. Even the mechanic said so.
That kit looks like the one I purchased from Bairs. If it is then it is incomplete. You will be missing 2 inner bearings.
Hope this helps.

Hey Turbo, have you heard from Ken about when the Vault will be up and running again?

Oh yea, also those ring gear bolts in the kit are not as beefy as the stock ones. Best to get the same type bolts or better that came from the factory.

Hey Ed, last I heard from him the dude that was supposed to install the cable modem didn't pack a raincoat and it was raining so he left. Haven't heard anything since.

I changed the gear ratio in my DANA 44 rear end along with replacing the bearings. Here is a link to my post about it.

I have completed setup of the 3.73:1 gears in my DANA 44 http://forums.corvetteforum.com/zerothread?id=193247

You can save a LOT of money by doing it yourself if you have the right tools for the job.
