(11) Release the lock bar on the column insert. Squeeze the legs of the column insert together and remove insert from steering column assembly (Fig. 7).

(12)Secure the insert and actuation cable out of the way.

(13)Remove tilt lever (if equipped) from steering column.

(14)Remove the upper and lower lock housing shrouds (Fig. 1) from the steering column assembly. Remove the lower fixed shroud from the steering column assembly. The shroud fasteners are Torxhead screws.

(15)Remove the wiring harness connector to the turn signal/multi-function switch using a 7mm socket as shown in (Fig. 8).

(17)Loosen the upper steering column support bracket nuts (Fig. 10) to allow some slack. This will aid in removal of the upper fixed shroud.

(18)Remove the upper fixed shroud (Fig. 1) from the steering column assembly. Remove the wiring

harness from the steering column assembly by prying out the plastic retainer buttons (Fig. 8).

(19)Remove the lower dash panel and support bracket standoff fasteners (Fig. 1).

(20)Remove the steering column assembly out through the passenger compartment. Use care to avoid damaging the paint or interior trim.

STEERING COLUMN INSTALLATION

(1)For column shift vehicles, install a new cable attaching grommet into the steering column shift lever (Fig. 11). Install grommet from the cable side of the lever. Use pliers and a back-up washer to snap the grommet into place (Fig. 11). Use Mopart Multipurpose Lubricant, or equivalent, to aid installation of the grommet. A replacement grommet should be used whenever the rod is disconnected from the lever.

(2)Install the ground clip on the left capsule slot (Fig. 12). The plastic capsules should be preassembled in the bracket slots. Remove the shipping lock pin (Fig. 1) located on lower column jacket when installing a new steering column.

Insert the column through the floor pan opening while being careful to avoid damaging the interior paint and trim.

(3)Position the steering column assembly in the vehicle. Align the steering column assembly mounting bracket slots on the brake pedal bracket attaching studs (Fig. 13). Install, but loose assemble the two upper column bracket, washers and nuts.

(4)Make sure the front wheels are in the straightahead position. Align and assemble the upper steering coupler to lower steering coupler. Install the up-

per to lower steering coupler retaining bolt and nut. Torque the retaining bolt nut to 28 NIm (250 in. lbs.).

Fig. 12 Ground Clip & Spacer Installation

Be sure to install the upper to lower steering coupler retaining bolt retention pin (Fig. 6).

(5)Install the buttons which retain the multi function switch wiring harness to the steering column. Connect the multi-function switch wiring harness

connector to the multi-function switch. Torque the connector retaining bolt to 2 NIm (17 in. lbs) using a 7mm socket (Fig. 8).

(6)Install the upper fixed shroud onto the steering column assembly.

(7)Be sure both breakaway capsules are fully seated in the slots of the steering column upper sup-

port bracket. Torque the 2 upper steering column assembly to support bracket nuts to 12 NIm (105 in.

lbs.). Torque the 2 lower steering column assembly to mounting bracket nuts to 12 NIm (105 in. lbs.).

Fig. 13 Steering Column Mounting

(8)Complete the wiring harness connections to the remaining steering column switches (Fig. 9). Install the lower fixed shroud onto the steering column.

(9)Route the PRNDL actuator assembly under left steering column wing and along left side of steering column. Insert the flange of the PRNDL actuator steering column insert into the steering column jacket (Fig. 7). Squeeze the legs of the steering column insert together and install tabs under steering column jacket. Engage lock bar to secure the actuator assembly into the steering column jacket (Fig. 7).

(10)Hook the PRNDL actuator cable eyelet to the steering column actuator arm (Fig. 7). Move the shift lever to neutral, check pointer location, should indicate neutral. If pointer does not indicate neutral adjust actuator with tool (Fig. 14) to center pointer on N (Neutral) and then check pointer location in other gears.

(11)Install the lock housing shrouds. The shroud fasteners are Torx-head screws. Install the tilt lever (if equipped).

(12)Install the lower dash panel cover.

(13)For steering wheel installation with speed control refer to Group 8 Electrical. For non-speed control, place the steering wheel on the steering column shaft with the master splines aligned. Install the steering

wheel to column shaft retaining nut. Tighten retaining nut to 61 NIm (45 ft. lbs.) torque. Do not force the steering wheel onto the column shaft by driving it on with a heavy object. Pull steering wheel down onto column shaft using ONLY the steering wheel retaining nut.

(14)For vehicles equipped with a column shift. Pass the transmission shift cable through its mounting bracket on the steering column assembly. Connect the transmission shift cable to the shift lever on the steering column assembly. Install the shift cable to mounting bracket retaining clip (Fig. 2). The grommet must be installed in the shift lever (Fig. 11) before the cable is inserted into the grommet.

Fig. 14 PRNDL Actuator Cable Adjustment

Use Mopart Multipurpose Lubricant, or an equivalent product, to aid installation of shift link rod into grommet.

(15)Re-adjust the transmission shift linkage.

Whenever the steering column is loosened or removed, the shift linkage MUST be adjusted and tested. Refer to Group 21 Transmission for the shift linkage adjustment procedure.

(16)Connect the battery ground (negative) cable. Test the operation of the lights and horns. If applicable, reset the clock and radio.

STEERING COLUMN COMPONENT SERVICE

The Acustar tilt and standard steering columns (Fig. 1) have been designed to be serviced as an assembly; less wiring, switches, shrouds, steering wheel, etc. Also most steering column components can be serviced without removing the steering column from the vehicle. For additional information on electrical components refer to Group 8H Electrical.

GEAR SHIFT LEVER

The gear shift lever (if equipped) is a serviceable component of the Acustar steering column assembly.

REMOVE

(1)Support the steering column assembly as shown in (Fig. 1) using a suitable size socket.

(2)Using a drift of the appropriate size drive the roll pin out of the steering column and gear shift lever (Fig. 1). Remove the gear shift lever from the steering column assembly.
