MEANING OF BAR BUSHING
Stabilizer bar bushings are rubber bushings designed to isolate the steel stabilizer bar from the vehicle frame and suspension. The stabilizer bar itself is typically connected to the lower control arms or another suspension component. Through a twisting action, the bar counteracts vehicle lean as you turn around a corner.
