Trailing arm bushings are part of a trailing arm suspension, where a series of interconnected “arms” join the axle and a pivot point on the chassis itself. The front of the trailing arm contains the bushing, and a bolt runs through the bushing to fasten the trailing arm to the frame of the vehicle. The trailing arm bushing cushions and eases the movement associated with suspension travel while firmly holding the wheel on its correct axis. If the trailing arm bushing is worn or cracked, the trailing arm can’t hold the rear wheel solidly on its axis, which can cause excessive tire wear on the affected rear wheel, a loose feeling when driving, cornering, braking, or accelerating, and clunking noises.
The trailing arm bushing is made of rubber in most cases and is subject to wear, weathering or cracking over time. This does not require replacement unless there is movement. However, if there is movement in your trailing arm bushing, you should have it replaced by one of our expert mechanics to prevent additional repair and maintenance costs or abnormal driving conditions.
The trailing arm is a link in the rear suspension and can present handling issues if excessive wear is present. Though wear will need to be extreme to present an unsafe driving condition, a worn trailing arm bushing can cause expensive additional repairs such as tire replacement. Have a worn trailing arm bushing replaced promptly.
