The steering column tube consists of a collapsible steel shaft, an intermediate shaft, and a steering column intermediate shaft coupling which connect the steering wheel to the steering gear. The steering wheel is attached to the steering column shaft, which is attached to the steering column intermediate shaft coupling. The steering column intermediate shaft coupling is attached to the steering gear input shaft.

The top of the steering column shaft is machined flat on two sides in order to key the steering wheel to the steering column shaft. The steering column shaft is housed in a cylindrical tube which mounts to the instrument panel reinforcement and vehicle bulkhead. Bearings support the shaft within the tube and ensure smooth rotation.

The steering column intermediate shaft coupling consists of the coupling, the intermediate shaft, and the universal joint. The coupling attaches the steering column shaft to the intermediate shaft. The universal joint connects the intermediate shaft to the steering gear input shaft. This design permits smooth operation while allowing for the steering gear input shaft angle.

A steering column support bracket and a steering column upper mounting bracket support the steering column in the vehicle.

Fixed and Tilt Columns
Fixed steering column tubes do not move up or down and are mounted similarly to tilt steering column tubes.

Tilt steering column tubes are fitted with a tilt mechanism that allows the steering column tube to adjust up or down. A tilt tilt wheel handle and shank is located underneath the steering column on vehicles so equipped. When the tilt wheel handle and shank is pushed downward, the steering column is allowed limited movement up and down to suit driver comfort. When the tilt wheel handle and shank is pulled up, the steering column is locked into position.

Steering Column Air Bag
The steering wheel is bolted to the top of the column and is fitted with a Supplemental Restraint System (SRS) driver side air bag module. Before performing work on or around any SRS component, observe all SRS conditions and warnings to avoid unnecessary air bag deployment and possible injury.

Steering Column Lock
The steering column lock is integral to the lock cylinder. When the ignition key is removed or turned to the LOCK position, a small key inside the steering column lock engages with the steering column tube, locking it into position. When the ignition key is turned to the OFF, START, or ON position, the steering column lock key withdraws, unlocking the steering column tube and allowing it to rotate.
