How Long do Shocks and Struts last? The shock absorbers and struts on your vehicle are in place to hold the tire firmly against the pavement, not to support the weight of your vehicle as is commonly misconceived. The weight of the vehicle is supported by the springs in conjunction with the suspension components. because of this demanding job of holding the tire firm against the pavement shocks and struts are constantly moving. This constant movement and dampening slowly wears the shocks and struts. Generally a good quality shock or strut will last 60,000 to 75,000 miles before showing signs of wear or requiring replacement. Sometimes the hydraulic fluid will begin to leak from the shock/strut unit, although most often there are no external signs of shock or strut replacement needs. All of the wear and tear is internal and the symptoms are diminished ride quality, tire wear and poor braking performance. Due to the fact that we drive the same car every day the gradual wear can be difficult to detect. You may seem to notice that your vehicle just doesn’t feel like it “used to”. So to keep your car operating as the finely tuned machine that you purchased have the Shocks and Struts inspected regularly and budget for replacement between 75,000 and 100,000 miles.
