Have you noticed any of the following?

• Loss of control
• swaying when making routine turns
• Bottoming-out on city streets
• Bouncing excessively on rough roads
• Pulling in one direction
• Bulges or blisters on the sidewalls, or dents in the rim

These symptoms can mean there's an alignment problem and are indicators that he steering and suspension may have been damaged. That's important because both are key safety-related systems.
