A three-wheeled vehicle steering and suspension system includes two support assemblies for two opposed front steerable wheels, the support assemblies each having a tubular housing welded to the vehicle frame, a cylindrical tube rotatably supported within the housing and a cylindrical rod slidably supported within the rotatable tube. Each rotatable tube is affixed at its outer end to the upright support assembly for one of the vehicle wheels and at its inner end to a shock-absorbing member for biasing the wheels into road contact and permitting independent movements thereof to adapt to road undulations. Each sliding rod is affixed at its outer end to the vertical turning shaft of the upright support assembly of one of the wheels and at its inner end to a reciprocal steering linkage for actuating synchronous turning movements of the wheels. In one embodiment, the shock absorbers are connected to opposed crank arms on a connecting shaft arrangement which is drivenly connected to the steering linkage for actuating opposed upward and downward vertical movements of the steerable wheels for causing leaning of the vehicle frame and body upon each turning movement thereof in the direction of vehicle turning.
