TRACKS AND SUSPENSION The track and suspension system consists of the vehicle tracks, final drives, sprocket wheel, universal joints, road wheels, idler wheels, idler hubs, shocks, and torsion bars. The relationship of these components is shown in the diagram below. When the track receives power from the transmission through the universal joint, final drives, and sprockets, the track begins to revolve around road wheels, over the idler wheels and back to the sprockets. This propels the vehicle forward and backward, depending on selected transmission gear. 3-94
