A steerable vehicle suspension can include an axle, at least one retractor having a length that decreases in response to a pressure increase applied to the retractor, and at least one wheel spindle. Resistance to rotation of the wheel spindle relative to the axle increases in response to the pressure increase applied to the retractor. A method of operating a steerable vehicle suspension of a vehicle can include allowing steering knuckles rotatably mounted at opposite ends of an axle to rotate relative to the axle while the vehicle moves forward, and applying an inwardly directed force simultaneously to each of the steering knuckles. Another steerable vehicle suspension can include two rotatably mounted steering knuckles, and two retractors connected to the steering knuckles. An inwardly directed force is applied by each retractor to a respective one of the steering knuckles in response to pressure applied to the retractors.
