Get the pattern marks too near the outside of the ring gear and same result as poor backlash...broken teeth the first time you back off the throttle then get back on it!
On a new install pinion depth and preload get set first . 0.003 is to tight you'll find the ring gear to have "tight" spots when that tight . I try and stay around .008-.010 . On a used gear the backlash must be set back to where it was before disassembly .
