My 2003 Avalanche has started making a noise that sounds like a right side wheel bearing. IE increases with speed on all road surfaces and lessens when turning right. I replaced the right wheel bearing even though it felt and sounded fine on jack stands. No change in noise. I am servicing the front diff today axle shafts boots are good and no clicking. tires rebalanced and rotated with no change. any other thoughts on possible sources to check for the noise
