Claim 9:
10. The steering system of claim 9, wherein the rack and pinion gearset is a manual rack and pinion gearset; wherein secured to a firewall is the augmented chain and sprocket assembly, the augmented chain and sprocket assembly is vertically oriented such that the first rounded end is at a top while the second rounded end is at a bottom, the input shaft of the augmented chain and sprocket assembly is directed backward towards the steering wheel and is pivotally connected to an end of a steering column while the output shaft of the augmented chain and sprocket assembly is directed forward towards the front axle and is pivotally connected to the back end of the coupler shaft, the front end of the coupler shaft is pivotally connected to an input shaft of an electric assist motor box while an output shaft of the electric assist motor box is pivotally connected to the back end of the steering shaft, and the front end of the steering shaft is pivotally connected to a pinion shaft of the manual rack and pinion gearset;
wherein cooperation among the augmented chain and sprocket assembly, coupler shaft, electric assist motor box, and steering shaft enables steering input to be transmitted from the steering column to the manual rack and pinion gearset;
wherein the manual rack and pinion gearset is attached to the front axle between a differential housing and a driver side inner-C end forging, a rack of the manual rack and pinion gearset is pivotally connected to the first end of the draglink while the second end of the draglink is pivotally connected to the passenger-side steering knuckle, the passenger-side steering knuckle is pivotally connected to the first end of the tie rod while the second end of the tie rod is pivotally connected to the driver-side steering knuckle;
wherein cooperation among the manual rack and pinion gearset, draglink, and tie rod enables steering input to be transmitted from the manual rack and pinion gearset to the driver-side and passenger-side steering knuckles, transmission of steering input to the driver-side and passenger-side steering knuckles enables the driver-side and passenger-side steering knuckles to turn, and thereby turn the vehicle.
