Well I am in the middle of installing the 4.10's. I bought the master install kit from rons. Problem is, My pinion bearing closest to the gear is bigger than the one included in the kit.....is this normal? I'm kinda at a stand still till I figure out whats up, naturally, all the parts stores are closed but I had them double check the numbers the other day and the packaged kit shows to have the right bearings???

there will be 2 carrior bearing same size each , then 2 pinion bearings one small for the nut side and one big for the gear side .

I know the large one goes on the gear end, my install kit for the "8.6" included both pinion bearings, the larger one is about 1/2 smaller than my factory bearing. I think I'll just press my factory one off tomorrow at work. What pisses me off is that I had 2 different parts stores look up the bearings for the pinion gear because i wanted to make some "setup bearings". Both parts stores came up with the same # that was included in my kit. Which are wrong

I had to go buy a setup bearing from the parts store myself, kind of slowed me down too. The kit bearing and race had a little different taper from the OEM stuff, I installed the kit race and got a matching bearing from the parts store and used that one for my setup bearing. Make sure you install the new kit race before you set it up.

Did you look at this for a part reference????

I did read the writeup. After some digging last night I found that the 09 and newer have larger o.d. Pinon bearings. So the 8.6 install kit I got from rons only works up to 08 on the pinion bearings anyhow. I pressed mine off today at work and onto the new pinion. My stock pinion had a .036 shim, I used it and will check pattern tonight when I get
home.

I would have measured the original bearing and race vs the new bearing and race before I added the shim. No biggie, but might help in the future.

I used the original bearing and race. neither pinion bearing in my install kit from ron's fit, they were too small on the outside diameter
