Installation
On all
models, aligning lower shaft with lower coupling
and insert
shaft. Raise column assembly into position onto studs.
Loosely
install nuts and washers in breakaway capsules. Pull
column
rearward. Tighten nuts to specification. See TORQUE
SPECIFICATIONS.

new shift lever grommet using pliers and back-up
washer to snap
the grommet into place. Use a multipurpose grease to
aid
installation.
Connect
gearshift cable rod to shift lever by snapping rod
into
grommet with pliers. Adjust linkage. Place steering wheel on
shaft
with master splines aligned. Place damper assembly inside
steering
wheel (if equipped). Install steering
wheel retaining nut.

STEERING WHEEL &
HORN REMOVAL article. Connect wiring connectors
at
steering column jacket. Connect
battery negative cable. Test operation
of
lights and horn.
On
models with A/T, install gearshift indicator pointer.
Slowly
move gearshift lever from "LOW" position to "PARK"
position,
pausing briefly at each selector position. Loosen and
readjust to
align pointer with each position (if necessary).
Install instrument
panel
steering column cover.
STEERING COLUMN (FLOOR SHIFT)
The steering column with a floor mounted gearshift is basically the same as previously described. Standard columns and service procedures are identical except as described below.
* In place of rotating shift housing, there is a plastic shroud which is fixed to lock housing. Shroud covers jacket and lock inhibitor assembly. It is held in place by a tab that fits under side cover and one screw. Shroud can only be replaced by removing lock housing from jacket.
The
lock inhibitor assembly consists of a lever that engages
lock
levers (preventing locking of steering shaft), a
button
to operate lever and a return
spring. Assembly is attached to
lock
housing in same location as shift gate is on column
shift.
Lower steering shaft bearing is mounted in an aluminum
support.
A spring
is attached between shift housing and column jacket.
This spring
keeps housing rotated counterclockwise against
rubber bumper.
