Where is the backlash marked?
Have a set of 4.10's from AA&M, where is the backlash setting marked? Reason I'm asking is because I have a slight whine at certian rpm's (2500 or so) at highway speed (65+) had the backlash at .007 but not sure what AA&M actually calls for on these gears.. is this typical of their 4.10's or do I need to recheck the backlash.. was kinda hoping they'd be quite as they're from the same company who makes OEM gm pieces..

Did you check the backlash in several places around the ring gear?
.007" should be fine. I aimed for .008" - .010" on mine and they are dead quiet at any speed, but they are Yukon gears.
