The steering column assembly is bolted to the bulkhead. The steering column shaft is mounted in two needle bearings suspended in rubber mountings in the steering column assembly. A jointed intermediate shaft connects the steering column to the power-assisted steering gear. For reasons of safety the steering column assembly incorporates a collapsible steel cage, a telescopic steering column shaft and an intermediate shaft with a deformation zone designed to crumple progressively in the event of a head-on collision. In addition, the joint configuration is such that the shaft will be directed away from the driver in a collision. Adjustment of the position of the steering wheel spokes is achieved by adjusting the toe-in on both sides of the car.
