NOTE:
All steering wheel and column fasteners are important parts in that they could affect the performance of
vital parts and systems, and / or could result in major repair expense. They must be replaced with one of
the same part number or with an equivalent part if replacement becomes necessary. Do not use a replace-
ment part of lesser quality of substitute design. Torque values must be used as specified during reassemb-
ly to assure proper retention of this part.

GENERAL DESCRIPTION
This double tube type steering column has the following three important features in addition to the steering function:

The column is energy absorbing, designed to compress in a front-end collision.

The ignition switch and lock are mounted conveniently on this column.

With the column mounted lock, the ignition and steering operations can be locked to inhibit theft of the vehicle.
To insure the energy absorbing action, it is important that only the specified bolts be used as designated and that
they are tightened to the specified torque. When the column assembly is removed from the vehicle, special care
must be taken in handling it. Use of a steering wheel puller other than the one recommended in this manual or a
sharp blow on the end of the steering shaft, leaning on the assembly, or dropping the assembly could shear the
plastic shear pins which maintain column length and position.
