ABSTRACT:
A steering system (10) for a four wheel drive, live axle vehicle (12) includes a rack and pinion steering gear assembly (80) including an elongate rack (100) having a longitudinal axis (102) and extending axially through a rack housing (82). The rack (100) is movable axially in the rack housing (82) in response to rotation of the vehicle steering wheel (104). A first end portion (108) of the rack (100) projects axially from the rack housing (82). A drag link (60) is connected between the first end portion of the rack and one of the first and second steering arms (40, 44) for transmitting steering force to the one (40) of the first and second steering arms. The drag link (60) is pivotally connected with the rack (100) at a location (130) on the rack axis (102). The drag link (60) has a kinematic axis (68) which extends generally parallel to the rack axis (102).
