hi guys, i had a speed shop install a new takeout auburn posi unit with 3.73 gears, and all new bearings including the axle bearings, it is a 28 spline unit, i noticed that sometimes, not all, when making a left turn kinda sharp, i get a moaning.., rubbing sound out of the right side of the rear, what would cause that?? they say they put the limited slip additive in it, could it be the brakes? they are drums, and i noticed they're not adjusted correctly after they did the rear.

 

if it's not gm additive i'd drain it and refill with gear oil and gm additive.

 

anyone else have a suggestion?, it doesnt sound like chatter it sounds like a big rubbing sound

 

No need for another suggestion. Any other suggestion would be wrong.
