Backlash off or normal? AA&M 4.10's

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..

slight whine is nothing to worry about.007 is fine,did you set the pinion depth when you installed them?
