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..
