Did the dealer get some photos? Was it a ring gear failure like Neo's and Bebe's? I wonder if AAM was having some problems back July; such as hardening of the gear set? Just wondering, but could lapping compound left on the gear set cause this type of ring gear failure? Anyone know? They did have that early problem with the rear axles and lapping compound left on the gear set during assembly. Just thinking to myself, I have no info on this, but I'm getting more curious as time goes on. |
The lapping compound would not cause a fracturing of the gear, rather, it would lead to excessive backlash and a howling noise. The catastrophic failure is likely a manufacturing defect and American Axle is going to have alot of 'splainin to do, not to mention compensation to GM for warranty repairs.
