I guess I just noticed that as the ring gear runout changes the backlash changes and the pattern changes.
I figured that happened, but just measured it and checked the patterns. So this has been messing with me the whole time. I would check backlash on the teeth meshing with the the pinion and paint teeth directly on the opposite side of the ring gear. Where the backlash would be not what I just measured cause of the run out. Then change shims and replace the carrier in a totally different spot and measure again getting a backlash measurement from a different spot ..just messing things up basically.
I checked ring gear run out along with backlash and noticed that for every .001 in runout the backlash changes .001.
I have a total of .002 runout and my backlash changes .002 from .008 to .010.
I GUESS the pictures up there that you said were "about perfect" must have been painted on a spot that was .007 . Cause the tighter I get the backlash the more It gets like that picture.
I understand that going from 27 inch lbs to 22 inch lbs PTT could change pinion depth but I wouldn't think it would change very much at all. Not enough for the average person to measure anyway.
I have to think, just the backlash changed.
The ring gear run out on the stock setup before I took it apart was .004, so its half what it was.
At this point, taking 4 measurements the average ring gear runout is .009
These pictures are the same shims just opposite sides of the ring gear. one side .010 backlash the other side .008 backlash.
.010 is the two on the left - .008 is the two on the right
