2. Remove the driver's dashboard lower cover and
driver's knee bolster (see section 20).
3. Remove the combination switch assembly from the
steering column sha{t by disconnecting the connec-
tors.
4. Disconnect the ignition switch connectors.
5. Remove the steering joint cover.
6. Bemove the steering joint bolls.
7. Disconnect the steering ioint by moving the joint
toward the column, and remove it from the column

NOTE:
. Make sure the steering joint is connected as follows:
a. Insert the upper end of the steering ioint onto the
steering shaft (line up the bolt hole with the flat on
the shait), and loosely install the upper joint bolt.
b. Slip the lower end of the steering joint onto the
pinion shaft (line up the bolt hole with the groove
around the shaft), and loosely install the lower
joint bolt.
Be sure that the lowei joint bolt is securely in the
groove in the pinion shaft.
c. Pull on the steering joint to make sure that the
steering joint js fully seated. Then tighten the ioint
bolts.
. 8e sure the wires are not caught or pinched by any
parts when installing the column
. Make sure the wire harness is routed and fastened
properly.
. Make sure the connectors are properly connected.

Steering Lock Replacement
SRS components are located in this area. Review theSRS component locations. precautions, and procedures
in the SRS section (24) before performing repairs or ser-vtce.
Remove:
LMake sure you have the anti-theft code for theradio, then wire down the frequencies for theradio's preset buttons ('99 - 00 models).
Disconnect the battery negative cable.
Remove the driver's dashboard lower cover andknee bolster (see section 20).
Disconnect the 5P connector from the under-dash
fuse/relay box and the 7P connector from the mainwire harness (see previous page).
Remove the steering column covers, then removethe mounting bolts and nuts from the steering col-umn (see section l7).
Lower the steering column assembly,
Center-punch each of the two shear bolts, then drilltheir heads off with a 5 mm (3/16 in) dritt bit.
CAUTION: Do not damago the steering lock body.
Remove the shear bolts and the steering lock assem,oty.
