• How often should you replace your shocks and struts?

• What causes shocks to freeze up?
• 2002 Lincoln Town Car: I’ve noticed a strange grinding sound coming from my car while idling. Is this related to my motor mounts?

• 2003 Chevrolet Avalanche: After replacing my water pump, my truck has shown several warning lights. What might have triggered this?
• 2002 BMW M3: What information can you give me about the reputation of the transmission in this vehicle?
• 2001 Dodge Ram 1500: I recently purchased this truck and the check engine light has come on. Is it possible this is just a gas cap issue?
