STEERING COLUMN
The left steering arm and the left and right tie rod arms are secured to the steering knuckles at one end
and to a drag link or tie rod at the other. The arms are retained with a key in the steering knuckle in the
fixed angular position necessary for proper steering.
Steering turning action is transferred by the upper and lower steering shafts, enclosed within the steering
column, directly to the input shaft of the steering gear.
The steering wheel is a three-spoke type, constructed of plastic resin over a steel framework. The horn
button is mounted in the center of the wheel. The steering column is adjustable in two directions—up
and down and fore and aft—by rotating the tilt lock lever counterclockwise to release it, adjusting the
column and wheel to the desired position, and then rotating the lever clockwise to again lock the column
and wheel into place.
The upper and lower shafts are connected by a universal joint. The lower shaft extends directly to the
steering gear input/worm shaft and is connected by a second U-joint, secured by a clamp bolt and nut.
The steering column is mounted to a reinforcement bracket which is bolted to the steering column sup-
port bracket in the dash assembly.
Steering Wheel Removal/Installation
Removal
1. Shut off the batteries at the main switch. Ensure the front wheels
are in the straight ahead position. Place a piece of tape on the
dash to mark the position of a spoke.
2. Press down on the horn button with the palm of the hand and
rotate the horn button in a counterclockwise direction to unlatch
it. Release the pressure slowly and note the relative positions of
the horn spring, contactor, and cap (Figure 5-12).
3. Remove the spring, contactor, and cap.
4. Remove the steering wheel nut and thrust washer.
5. Install a wheel puller and remove the steering wheel from the
hub.
Installation
1. Position steering wheel on steering column and match the previ-
ously marked spoke with the tape on the dash.
2. Install the thrust washer and large nut on the steering column
shaft. Tighten the nut to 45–55 ft-lb (60–75 N-m) torque.
3. Install the horn spring, contactor, and cap.
4. Install the horn button by pressing down on the horn button and
rotating it in the clockwise direction.
