An off-road vehicle includes a frame and wheels. An engine powers the
wheels through a drive system that includes a front differential gear
unit. A housing encloses the front differential gear unit. The housing is
positioned generally on a longitudinal center plane of the frame with the
plane extending generally vertically and fore to aft. A steering system
controls directional movement of the front wheels. The steering system
includes a steering wheel that is offset relative to the center plane. A
steering shaft is connected to the steering wheel and is disposed on the
frame for rotation. A pair of tie-rods are coupled with the respective
front wheels. A coupling mechanism couples the steering shaft to the
tie-rods. The coupling mechanism converts the rotary movement of the
steering shaft to an axial movement of each tie-rod. The coupling
mechanism includes a rack-and-pinion assembly. A gear case encloses the
rack-and-pinion assembly. The gear case is coupled with the differential
housing and positioned such that the center plane intersects the gear
case.
