Introduction

Print

All models have recirculating ball type steering. Forces are transmitted from a worm to a sector gear through ball bearings. Relay type steering linkage is used with a pitman arm connected to one end of the relay rod. The other end of the relay rod is connected to an idle arm which is attached to the frame. The relay rod is connected to the steering arms by two adjustable tie rods. Most models are equipped with a collapsible steering column which is designed to absorb and impact by collapsing, thereby reducing possible chest injuries during accidents. When making any repairs to the steering column or steering wheel, excessive pressure or force capable of collapsing the column must be avoided for this reason. The ignition lock, ignition switch, and an anti-theft system are built into each column. The key cannot be removed unless the transmission is in PARK with the switch in the LOCK position. Placing the lock in the LOCK position activates a rod within the column which locks the steering wheel and shift lever. On floorshift models, a back drive linkage between the floorshift and the column produces the same effect.
