Claim 0:
1. A suspension system for a vehicle, the suspension system comprising:
a cylinder coupled to a wheel;
a piston rod disposed at least partially in the cylinder and extending from the cylinder along an axial direction to a distal end, the piston rod being configured to move relative to the cylinder;
a seal between the cylinder and the piston rod; and
a bushing structure coupled to the distal end of the piston rod, the bushing structure having a first end coupled to the distal end of the rod and a second end spaced from the first end along the axial direction, the bushing structure being configured such that a change in a load applied generally along the axial direction causes the first end of the bushing structure to rotate relative to the second end of the bushing structure, such that the piston rod rotates relative to the cylinder to overcome a static friction force at the seal.
