Do not wait until rubber is worn or brittle to replace them. Wiper blades should be replaced at least once per year, and more often if smearing or chattering occurs. Be sure all your lights are clean and working, including brake lights, turn signals and emergency flashers. Keep spare bulbs and fuses in your vehicle. Check for cuts, bulges and excessive tread wire.
Uneven wear indicates tires are misaligned or out of balance.
Keep a record of tire rotation. Rotate at the first 5,000 miles and every 7,500 miles thereafter. Look for signs of oil seepage on shock absorbers. Test shock action by bouncing the car up and down. The car should stop bouncing when you step back.
