Just got off the phone with Hendrick Hummer and my rear axle is going to be replaced too.
I've been hearing a whining noise and my stabilty control malfunction warning was going off. Said axle replace and sensor on axle as well as roof rails and jack (recall).
I'm with ya now for at least 7 days. Although, I have a Cadillac Escallade (pimp in) as my loaner.
