Pontiac G5 Sway Bar Frame Bushing

The Sway bar frame bushings are basically rubber or bushing blocks that grip the stabiliser bar, also known as the sway bar, which helps to secure it to the body or frame of the vehicle. There will usually be one or two bushings on each of the stabiliser bars, held together via bushing brackets. Using the stabiliser bushing and the bushing braces, the stabiliser bar is firmly placed under torsion from the vehicle's weight.

The stabilizer bar or sway bar is used to tackle vehicle roll in a turn. Also leans when the car turns the vehicle's weight, or rolls to the outside of the turn up to 30 degrees which puts more weight on the outside tires and less weight on the inside tires. This weight differential affects both stability and vehicle steering and handling, the stabilizer bar uses torsion to move the outside weight to the inside, thereby providing a balance as the vehicle turns. The sway bar bushings bind together the stabilizer and the body frame of the vehicle.

The sway bar is fixed to the vehicle's body / frame, with sway bar bushings. Two sway bar bushings are usually present for each sway bar. Thereby, the sway bar bushings can isolate the sway bar from the body or frame, reducing noise.
