What Does a Broken Suspension Feel Like?

A broken suspension can lead to a bumpy and uncomfortable ride. You might experience excessive bouncing, uneven tire wear, and difficulty steering or controlling your truck. If you notice these signs, it's time to get your suspension checked by our skilled technicians.

How Often Should I Have My Truck’s Suspension Inspected?

Regular suspension inspections are crucial for maintaining safety and performance. We recommend getting your truck's suspension checked at least once a year or every 12,000 miles. If you frequently drive on rough terrain, consider more frequent inspections to catch potential issues early.
