Preliminary Inspection

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 Chevrolet Tahoe, 2003 Chevrolet Suburban, and 2003 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

Important: Ensure the brakes are fully released and do not drag.

Pull or push the tire at the top back and forth in order to test the wheel bearing play.

Use a pry bar under the tire as an alternative.
If the wheel bearing adjustment is correct, the movement will be barely noticeable.
If the movement is excessive, adjust the bearings.
