The lifespan of a car suspension depends on the type of suspension system and the conditions in which the vehicle is used. On average, a suspension system can last anywhere from 50,000 to 100,000 miles (80,000 to 160,000 km). However, this can vary based on factors such as road conditions, driving style, and the type of suspension. For example, off-road vehicles may experience more wear on their suspension components due to rough terrains, while cars driven primarily on highways might last longer. Suspension systems that include shock absorbers or struts will wear out over time, especially if subjected to frequent bumps or heavy loads. Proper maintenance, such as regular inspections and timely replacement of worn-out parts, can extend the life of the suspension. Common signs of a failing suspension include uneven tire wear, difficulty steering, and a rougher ride, which indicates it may be time for repairs or replacements.
