As a suspension trailing arm in the rear lower position, it connects the rear axle to the vehicle's structure and helps locate the axle front to back as the suspension moves. Signs it may need replacing include clunking from the rear over bumps, wandering or vague handling, uneven rear tire wear, or a cracked, bent or heavily rusted arm. If a worn or damaged trailing arm is the cause, this part replaces it. Inspect the related suspension components at the same time.
