I spent nearly 16hrs this weekend dinkin around trying to get a good gear pattern in my D44. To give some background, these are used gears but out of the same case they came from. I was just changing the carrier bearings. I can get a relatively nice pattern centered on the drive side but the coast side is less than desirable where it sits high and toward toe. I even have the backlash to the max between 9-10 thou. I'm at the end of my rope. I was stupid and didn't measure or take a pattern reading before I changed the bearings to get a reference. Should I be happy with a good drive side?:-\
