DESCRIPTION AND OPERATION

STEERING WHEEL AND COLUMN DESCRIPTION AND OPERATION

The steering wheel and column has 4 primary functions:

Vehicle steering

Vehicle security

Driver convenience

Driver safety

Vehicle Steering

The steering wheel is the first link between the driver and the vehicle. The steering wheel is
fastened to a steering shaft within the column. At the lower end of the column, the intermediate
shaft connects the column to the steering gear.

IMPORTANT: If reusing the existing sensor, you must align the marks on

the flush rotor flange cuff before installation. The alignment
mark must stay aligned until the sensor is seated into the
adapter and bearing assembly.
If installing a new sensor, it will come with a pin installed in
the sensor. Do not remove the pin until the sensor is seated.
If the new sensor did not come with a pin installed, you must
reorder a new sensor.

Driver Safety

The steering wheel and column has safety features to protect the driver. The following
components may be mounted on or near the steering column:

Energy-Absorbing Steering Column

The energy-absorbing steering column compresses in the event of a front-end collision,
which reduces the chance of injury to the driver. The energy-absorbing feature, collapsible
steering shaft and break away mounting features help reduce the injury in the event of an
accident. In addition to these features, the following driver safety features may be on the
