Principles of Operation: Notes

Steering Column -   The steering column is the mechanical linkage between the steering wheel and the steering gear. It houses the steering column switches and is able to tilt to various positions for driver preference. The steering wheel is bolted to the steering column shaft that runs down the center of the steering column. The steering column shaft goes through the dash panel and connects to the steering gear. The steering column shaft connections are made by U-joint type couplings. The steering column shaft is centered by roller ball bearings, which are contained within the steering column. The power tilt steering column is controlled by an electrical motor that is activated by a rocker-type switch located on the LH side of the steering column just below the multi-function switch. When the power tilt switch is pressed, it allows the steering column to adjust up or down. The switch is not serviceable, if a new switch is needed then a new steering column lower shroud must be installed. The power tilt motor is not serviceable, if a new motor is needed then a new steering column must be installed. The other steering column switches (multi-function and ignition) are mounted to the steering column. These switches are covered by the upper and lower steering column shrouds and can be accessed by removing the shrouds.
