First time setting up gears but fairly experienced wrencher. So I’m in the process of installing 513 revolution gears in my 2005 TJ with a stock Dana 30, in place of the 373. The old setup that was in the jeep was only making contact on the very very toe of the ring gear so I started with a blank slate. My current setup has 7thou backlash and is giving me these patterns. I am using setup bearings, yes I know some of you don’t like that but I’ll deal minor adjustments later. Not sure if I need to add pinion shims or take away. Any advice would be appreciated.
