Matt,
Your Patriot does not have torsion bars. You are probably talking about the control rods that control the axle location as it travels up and down in relation to the coach frame. Some of these bushings are replaceable, but most of them are not. You have to replace the whole rod. If you think the bushing is bad because of the cosmetic appearance of the outside edges, you may be wrong. As long as the bushing has no looseness between the internal sleeve and the rod itself, it is OK.
