Like your car's brake system, the steering and suspension systems are key safety=related systems. Together, they largely determine your car's ride and handling.  Have your car's steering and suspension systems checked regularly, at least once a year and usually with a wheel alignment.

The suspension maintains the relationship between the wheels and the frame or unibody.  The suspension system interacts with the steering system to provide vehicle control.  When working properly, the suspension system helps absorb the energy from road irregularities such as potholes and helps to maintain vehicle stability. 

Over time, steering and suspension components wear out and require replacement.  Regular checks are critical to maintain a safe car.  Factor that affect wear include:

• Driving habits
• Operating conditions
• Vehicle type
• Type of steering and suspension system
• Frequency of regular maintenance such as chassis lubrication and wheel alignment

Symptoms are pulling, uneven tire wear, noise and vibration while cornering, loss of control.
