1. A vehicle comprising:
a chassis including:
a first frame rail defining a first vertical plane; and
a second frame rail spaced from the first frame rail, the second frame rail defining a second vertical plane; and
a front axle assembly coupled to a front end of the chassis, the front axle assembly including:
a solid axle; and
a steering assembly including:
a pair of wheel hubs coupled to opposing ends of the solid axle, the pair of wheel hubs configured to facilitate coupling wheels to the front axle assembly;
a steering gear mechanism positioned between the first vertical plane and the second vertical plane, the steering gear mechanism including a first gear box and a second gear box, wherein the first gear box is positioned between the first vertical plane and a central vertical plane centrally positioned between the first vertical plane and the second vertical plane, and wherein the second gear box is positioned between the second vertical plane and the central vertical plane; and
a linkage assembly coupling the steering gear mechanism to the pair of wheel hubs to facilitate steering the pair of wheel hubs through actuation of the steering gear mechanism, the linkage assembly including (i) a pair of pitman arms coupled to the steering gear mechanism, (ii) a pair of steering links coupled to the pair of pitman arms such that the pair of pitman arms couple the first gear box and the second gear box to the pair of steering links, and (iii) a pair of tie rod arms coupling the pair of steering links to the pair of wheel hubs.
