I just rebuilt mine. Rebuild kit, new chain, new rear sye bearing & seal and new bearing plates for the low range gear. Cost $240.00 including shipping. Took about 8-10 hours to remove, rebuild and re-install. Had to have the front yoke pilot bearing pulled by a shop. It was stuck tight and took two of us with the right tool about 15 Minuit's to remove. I knew the guy, so it was free.
