I'm swapping out my 8.25 with 3.07's for an 8.25 29-spline 4.10 gear axle. Normal hand tools are all you'll need, along with a few jacks and jack stands. IIRC, 8mm for the driveshaft, 3/4" for the shocks and U-bolts, pliers for any brake stuff on the rear axle, and 14mm and 3/8" for the brake line.
