My rear suspension is Ridewell RAD227. There is a bar that runs from the PS frame to the DS axle and locates the axle from shifting side to side. Mine had tie rod type ball joints that were totally worn out & allowed for some exciting handling. Ridewell refers to this bar as a sway bar. On a car that has this component it is called a panhard rod. A sway bar is a different component that controls roll. On class 8 trucks, this component is called a transverse torque rod.
Just wanted to clairify this & I recommend that these bars be checked.
