I was finally able to finish all of my other cars that managed to break down over the winter. I got back onto the 14 bolt axle today and was able to slide the new ring gear and differential inside. After setting up the preload I went to measure for backlash. I made the necessary adjustments and got it close. I put the dial indicator on the ring gear and came up with some bizarre readings. I understand that ring gear will usually have one or two thousandths variation but this one is boggling me. Before I put the ring gear on the carrier I made sure to deburr the ring gear itself and I also checked for any imperfections on the new Eaton differential. I pretty much measured every tooth or every other tooth going around the differential. These are the readings in thousands.

You can see in the picture where I drew the readings on the differential with the corresponding tooth. I took the differential out once and reinstalled it when I first got these readings. The bearing caps are torqued to spec and the ring gear bolts are all torqued to spec. Any ideas or thoughts from the gear heads out there?
The pinion gear is installed and the pinion housing bolts are torqued to spec.
Has anybody run into this before? Besides separating the ring gear from the differential again are there any other solutions.
