Whether you get a rebuild or buy new (I would strongly consider new) get a variable ratio box and not a constant ratio. The original box is a constant and the variable will give you a much better road feel. You can buy aftermarket boxes with varying degrees of increased effort. I put an AGR rockcrawler box in my Jimmy, a constant ratio, and if I had to do it again, I would STILL get an AGR box, just the variable ratio. Two wheel drive boxes seldomly wear out like the 4x boxes, but an increased effort, variable fast ratio box will make your truck drive a TON better.
