Wheel Alignment and Tire Balance The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. Scheduled wheel alignment and wheel balancing are not needed. However, if you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced. If you need to replace any of your wheels or wheel bolts, replace them only with new Saturn original equipment parts. This way, you will be sure to have the right wheel and wheel bolts for your Saturn. {CAUTION: Using the wrong replacement wheels or wheel bolts on your vehicle can be dangerous. It could affect the braking and handling of your vehicle, make your tires lose air and make you lose control. You could have a collision in which you or others could be injured. Always use the correct wheel and wheel bolts for replacement. Notice: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance and tire or tire chain clearance to the body and chassis. See Changing a Flat Tire on page 5-70 for more information. Wheel Replacement Replace any wheel that is bent, cracked or badly rusted or corroded. If wheel bolts keep coming loose, the wheel and wheel bolts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your Saturn Retailer if any of these conditions exist. Your retailer will know the kind of wheel or wheel bolt 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. 5-67
