Well, after finally realizing that my backlash and gear pattern were greatly affected by installing the cover, I had to start all over again.
Everytime I wanted to check gear pattern and backlash, I had to install the cover then carefully remove it and check.
So since I had to start over, I used the original pinion shim and carrier shims and checked. Pattern indicated the pinion was too far away from the ring gear with contact of the drive side at the toe and towards the crown and coast side at the heel. Backlash was .012" so no go there.
I had a .010" pinion shim that I picked up at my local repair shop that he gave me. I installed that and checked again. The pattern wasn't perfect but looked good enough I felt ok to run it. Backlash was a little tight at .0035"-.004" using the original carrier shims. With that set up and the solid crush sleeve, my preload was around 12lb/in. At this point I was pretty well done with it. I have had the Treg down around a month so my patience was done haha.
This was a hell of an experience and I don't think I could have accomplished it without your help Dragline! Not to mention my father who did the lathe work.
I don't know how well you can see my final pattern but the drive side was still a little more towards toe but the coast was smack dab in the middle. I feel if I could have gone maybe another .003"-.005" added to the pinion, it would have been perfect but didn't want to go through the hassle of making another set of carrier shims.
I will know how it is when I drive it. During removal, I snapped the front left subframe bolt in two. That in itself has been the real challenge. Once that's out of the way, she's back together. If all goes well, I plan on posting up my method for rebuild on here with as much detail as I can.
