So there I was, painting gear teeth.....Finally I'm making some real progress and actually getting the backlash and gear pattern figured out, so I can get this axle finished. This took a VERY long time and much longer than I anticipated, but that's part of learning and part of projects you have to fit between other projects.
It's finally time to install the correct gear ratio for my Jeep with the R2.8 Cummins. Testing different tire sizes suggested 3.73s would compliment 33s very well with the R2.8 Cummins. Selectable lockers, upgrading worn steering and suspension components were naturally warranted as well. I started with the front Dana 30 and here's the start to a LONG journey to improve the drivability of my TJ. This is my first time setting up gears, so bear with me as I figure out my process of getting the correct backlash, bearing pre-load, gear pattern, etc.
Btw this has been edited in hindsight, so you may think I know what I'm doing and you will also miss countless hours of wasting time, experimenting with rules of thumb.
