1) What was the whine/noise thing a while back about the rear diff where they replaced it. Lapping compound left on the gears by the manufacturer (American Gear/Axle). Needless to say, over a period of time, it lapped the gears a bit too much . Does not affect vehicles built after August 10, 2005.

2) Anyone else spun out or broke either their front or rear diffs/ring/pinion/spider gears?
Top warranty hits show no front axles replaced, some rear axles, but that should be explanable by the previous issue (lapping compound). This does not mean there were no axles replaced for other reasons, but the number was too small to appear in a top 200 warranty issue report, and puts the instances per thousand vehicles at a very low number.

3) Which ring/pinion is in both the front and rear.... tooth count on the ring gear, etc?Can't help right now, system is down. But from my old memory, I believe front axle is 7.5, rear axle is 8.6. Not sure if I have teeth count anywhere, but when the GM system gets up and running again, I'll check.
