What Is a Trailing Arm Bushing
A trailing arm bushing is a connector that is used in automobile suspension. The bushing helps connect the rear axle of the car to the rest of the transmission system.
Significance
A trailing arm suspension is a type of car suspension; one or more connective links hook the cars chassis to the rear axle of the car. The trailing arm bushing is a special type of dampener that is made out of rubber. It is located between the connecting rods and the rear axle.
Function
The main function of a trailing arm bushing is to dampen the energy that is transmitted between the connecting rods and the axle. The bushing is located between the outside of the rod and the sheaths in which they sit. This allows the parts to connect to each other without grinding. The bushing can also minimize noise and vibration.
Considerations
Most trailing arm bushings are made out of rubber. This makes them more prone to deterioration than bushings that are made out of stronger materials. The natural flexibility of rubber can also cause a slight degradation in the vehicles handling during intense driving conditions. Polyurethane bushings are usually a better choice, due to their increased durability and slightly higher hardness.
