Torsion bushings control movement from the Torsion Bar and Torsion Arm. They allow the Suspension to rotate with the Control Arm and Hub Assembly. This movement is slightly off axis and can "load" the stock rubber bushings. They are located within the cars front sub frame, paralell to the torsion bar.
The stock OEM bushings deflect the load applied by the torsion arm, causing loading, preventing the suspension to work as it is inteded. OEM bushings do wear out and once they do, the arm will flex inside of the Torsion Tube and not transfer load properly.
