Removal/lnstallation
SRS components are located in this area. Review the
SRS component locations, precautions, and proceclures
in the SRS sectron (24) before pertorming repairs or ser-
vice.
NOTE: Before removing the steering column for SRS,
remove the driver's airbag assembly and cable reel lsee
section 24).
1. Remove the steering wheel (see page 17 35).
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
shaft.
8. Remove the steering column by removing the
attaching nuts and bolt.

9. Installation is the reverse of the removal procedure
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.
