There should be some kind of bearing retainer, a bearing/race, and some sort of shim to fit in the housing and a seal.

The first to go on the shaft, on the bottom when the splines are in the air and the flange is on the ground, is the bearing retainer, then the brake backing plate, then the bearing, then the race, then the shim, or shims. The shim will probably be a round block. The seal is pressed to the back of the housing,CAREFULLY. Then the whole thing goes in, the four bolts on the bearing retainer bolt to the axle end. Lube the seals with some oil to prevent burning them up before oil can reach them.

Hope it helps I've taken a few apart to fix them, and install them. Any more q's write Me. Good luck.

I would call Yukon Gear or whoever you made the purchase from and ask for the instructions. That way there will be no misinterpretation of some one else's directions. Correct installation of your axle kit can affect the safety of your vehicle as well as eliminate the possibility of messing something up.

I second calling the manufacturer. Get it right the first time.

Some donut hole that had my CJ before I got it didn't install a set of Moser's correctly.. I pulled them to fix a leaky seal and the bearings (what was left of them) fell apart in my hands. Whoever installed them left the spacer out and the bearing came apart in the tube, chewing up the brake backing plate and end of the axle tube. The bearing rollers looked like pistol slugs shot through a 2x4.

I ordered a new set of bearing and seals, and follwed the instructions... about 4500 miles now, without problems.

Check their website. I think I remember seeing instructions on their. They also have a great gear installation write-up. I would link directly, but I don't have adobe acrobat on this computer so I can't get to that page but their website is
