Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
the rear end in my Avalanche has a whirring sound notice it gets quite taking curves when the pressure is on the rear driver side, the noise is louder as you take a curve to the left with pressure on the passenger wheel. I've had the inner axle bearings replced, and heard GM had a problen with the interim shaft....any sugesstions?

Have a good ATRA certified transmission shop test drive your Chevy. It could be the rear diff, ouert axle bearings, worn gear set, you name it, So have a good trans person drive it with you and listen to your truck in person, so you won't be guessing.
