A trailing arm bushing isolates vibration and allows controlled movement where the arm attaches to the vehicle. Signs it may need replacing include clunking or knocking over bumps, wandering or loose handling, uneven tire wear, and a bushing that looks cracked, torn or separated. If a worn bushing is the cause, this Dorman part replaces it. Replacing the left and right sides together is recommended for balanced handling.
