In most cases, you will not need to have your wheels aligned again. However, if you notice unusual tire wear or your vehicle pulling one way or theother, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to berebalanced. Wheel Replacement Replace any wheel that is bent, cracked or badly rusted. If wheel nuts keep coming loose, the wheel, wheel bolts, and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your Buick dealer if any of these conditions exist. Your dealer will know the kind of wheel you need. Each new wheel should have the same load carrying capacity, diameter, width, offset, and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts, or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts, and wheel nuts for your Buick model. I NOTICE: The wrong wheel can also cause problems with bearing life, brake cooling, speedometerlodometer calibration, headlight aim, bumper height, vehicle ground clearance, and tireor tire chain clearance the body and to chassis. 266
