INSPECTION



  1. Before putting on the wheels, check for any cracks on the wheels or enlarged bolt holes, remove any corrosion on the mounting surfaces with a wire brush. Installation of wheels without a good metal-tometal contact at the mounting surface can cause wheel nuts to loosen. Recheck the wheels after 1,000 miles of driving.
