You may not give much thought to shocks or struts until they start to wear out, but it's important for every driver to know what to look for when it's time to take your car in for a checkup. When shocks and struts begin wearing out, your ability to control your vehicle is compromised, and so is the overall comfort of your ride. In addition, failing shocks and struts can affect other parts of your car and lead to additional expensive repairs or replacements.
