What is it?
The steering and suspension systems are key safety-related systems that largely determine your car's ride and handling. Have these systems checked regularly, at least once a year and usually with a wheel alignment.
What does it do?
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. The steering system transmits your input from the steering wheel to the steering gear and other steering components to control the car's direction.
Typical Wear and Tear
Over time, steering and suspension components wear out and require replacement. Regular checks are critical to maintain a safe car. Factors that affect wear include:
Driving habits
Operating conditions (potholes in road)
Vehicle type
Type of steering and suspension system
Frequency of regular maintenance such as chassis lubrication and wheel alignment
Symptoms
Car pulls to one side
Uneven tire wear
Excessive noise, vibration or bouncing
Loss of control
