Look for a master kit form Yukon. Replacing the bearings is going to require you to setup the gears so you will need shims, a clam shell bearing puller and a press. Check out pirate 4x4 for some good writeup on setting up gears.

Before you start, do some reading on what's needed. Setting up gears is not something most people can tackle by them selves. Just the bearing puller that you will need is over $300 for the cheep one. The basic process is to pull the shafts out, pull the cover, mark the bearing caps for side and direction, pull the caps off, pull the carrier out, unbolt the pinion and hammer it out making sure it doesn't take off and fall on the ground, pull the bearings, measure the shims. Install equivalent shims, press new pinion bearing into place, install pinion and set preload. Install bearings and shims on carrier, install carrier in diff, check gear pattern. Remove everything again, change shims, reinstall, check pattern, repeat as necessary till pattern is good or you go insane. Reinstall shafts, fill with oil and drive.

I would seriously consider paying someone to do this. There really is some voo-doo to getting gears set up perfectly. I installed lockers and new gear-sets in both the front and rear diffs (similar to a Ford 9in.) of my Land Rover. I had the benefit of a large heated garage with a lift, the knowledge and help of a heavy equip./Porsche master mechanic, and every high-end tool or piece of equipment you could imagine. It took us two LONG days from start to finish. I thought I would have a big sense of accomplishment after we were finished, but all I could think was, why the hell did I not pay someone to do this for me!
