STEER NG WHEELS AND COLUMNS
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

5. With wheels in a straight ahead position and the
steering gear on highpoint, check the steering
wheel alignment (Fig.
1). If the spokes are not
within the
limits specified, the wheel should be
removed
and centered. (See steering wheel
removal in this section).
NOTICE: The outer mast jacket shift tube,
steering shaft and instrument panel mounting
bracket are designed as energy absorbing units.
Because of the design of these components, it is
absolutely necessary to handle the column with
care when performing any service operation.
Avoid hammering, jarring, dropping or leaning on
any portion of the column.
NOTICE: When reassembling the column
components, use only the specified screws, nuts
and bolts and tighten to specified torque. Care
should be exercised in using over-length screws or
bolts as they may prevent a portion of the column
from compressing under impact.
I COLUMN REMOVAL AND INSTALLATION
The front of dash mounting plates must be
loosened whenever the steering column is to be lowered
from the instrument panel.
Refer to Fig. 3B5-3 for view of column attachment
provisions.
1. Remove nut and bolt from upper intermediate
shaft coupling. Separate coupling from lower end
of steering column. See Figure
3B5-4.
] 2. Disconnect shift linkage from lower shift lever.
3. Disconnect all electrical connectors from column
assembly.
4. Remove screws securing toe pan cover to floor
5. Remove nuts securing bracket to instrument
panel.
ON-CAR SERVICE
STEERING COLUMN
To perform service procedures on the steering
column upper end components, it is not necessary to
remove the column from the vehicle.
The steering wheel, horn components, directional
signal switch, ignition lock cylinder and ignition key
warning switch may be removed with the column
remaining in the vehicle as described earlier in this
section.
