    That's too much for a stock swap and if you are correct that the pinion bearings and the gear set is OK, it will be very simple for the layman to swap stock diffs. There are no adjustments as long as you use the side bearing shims on the proper side they came out of the housing you are still using and the caps get torqued. It's not the book way, but it is the 98% way.

    Totally agree with the above ^

    Had to deal with my spider gears going out and the local shop wanted to try quoting me $1200 cause their thieves out here... I marked the ring and pinion location along with mic the shims for reference n kept them on their respective side. No problems or whine luckily for over 40k miles now.

    OH btw... nice bust ya got there

    I went and got my carrierr bearings today! friend of mine at the store gave them to me for his cost! Im debating on spending the money on a true track. Found a company on ebay selling them shipped for $405 my question is would i still be ok by just putting it back in with the old shims like they were or if going to a aftermarket diff throw it off that much?

    If you replace g80 with g80 you are going to have to replace it again unless you drive like granpa Moses. Wasted money in my opinion.

    you will need it set up correctly. Get some one to help you with that. I hear Nathan/GasGuzzler works cheap and does good work.

    Cheap and good work just dont sound right together, especially on the installers half.
