NOTICE: All steering wheel and column fasteners are important attaching 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
replacement part of lesser quality or substitute design. 'Torque values must be used as specified during reassembly
to assure proper retention of all parts. There is to be no welding as
it may result in extensive damage and weakening
of the metal.
For prevailing torque
nut(s) and bolts(s), refer to the "Reuse of Prevailing Torque Nut(<) and Bolt(s) " chart
in Section OA.

GENERAL DESCRIPTION
STEERING COLUMN
The function locking energy absorbing steering
column includes three important features in addition
to the steering function:
1. 'The column is energy absorbing, designed to
compress in a front-end collision to minimize the
possibility of an injury to the driver of the car.
2. The ignition switch and lock are mounted
conveniently on this column.
3. With the column mounted lock, the ignition and
steering operations can be locked to inhibit theft
of the car.
The turn signal lever provides for control of
headlight beams, windshield washer and wipers.
The column may be easily
disassembled and Fig. 385-1 Steering Wheel Alignment ~ypical
reassembled. To insure the energy absorbing action, it
