Historically, domestic auto manufacturers produced large, rear-wheel-drive vehicles. However, during the 1970s, they began to shift toward producing lighter, front-wheel-drive vehicles that were more fuel efficient. This transition necessitated changes in vehicle suspension systems. Thanks to the typical construction of front-wheel-drive vehicles, the MacPherson strut suspension is considered to be the gold standard. MacPherson struts are dependable and durable components that provide both structural support and shock dampening. However, no matter how durable they are, all struts do sustain damage from wear and tear over time. Typical Lifespan of Struts On average, most struts need to be replaced after 60,000 to 100,000 miles. However, this can vary from one manufacturer to the next. Some manufacturers recommend replacing the struts as part of your routine maintenance at intervals of 50,000 to 100,000 miles, depending on the manufacturer. However, other experts recommend not replacing the struts until they show signs of damage. Signs of Damaged Struts If you don’t plan to replace your struts as part of your car’s routine maintenance, you should learn how to identify the signs that your struts are getting worn out. While the shocks provide the majority of the shock absorption, the struts also help dampen shock and keep the vehicle on the road. If your struts are getting worn out, you’ll likely notice that your car is bouncing excessively, especially when you drive on uneven roads or over bumps. Your car might also feel less stable or more wobbly than it should. Other signs of damaged struts include having the front end of the car dip when you brake or the rear end squat down during acceleration. In some cases, customers bring their cars into the auto shop because they hear unusual “knocking” noises. These noises can also indicate problems with the suspension system.
