2002 Chevy Silverado Wheel Bearings or ball joints?

I'm not saying the ball joints or wheel bearings are bad, but it sounds like an alignment problem. Also, have you checked to make sure the tires are properly balanced? Finally, is the tread on the tires cupped or worn in a manner that could cause a vibration?

The inner tire wear is a "tow - in / out" problem. The tires are not facing in the same direction. They are pointing away from each other. As a result, the tires wear as described.

Let me know.
