7. Remove combination switch & spiral cable from steering column
assembly. Refer to SRS-42, "
Removal and Installation" .
8. Disconnect the following connector from steering column
assembly.

Steering lock harness connector

Ignition switch harness connector

Key switch harness connector
9. Remove control unit with VDC/TCS/ABS control unit. Refer to
BRC-129, "
VDC/TCS/ABS CONTROL UNIT" .
10. Disconnect brake switch harness connector.
11. Remove steering column shaft from lower shaft in the following
procedure.
a. Remove lock nut from yoke.
b. Turn steering wheel to the right to appear the head of bolt.
c. Remove the fixed part of collar for bolt to the outside of its head,
remove bolt.
d. Remove the set lib of steering column assembly side from yoke,
push it equal to the thick part of yoke.
NOTE:
Because collar is set in lower shaft, if the set lib is pushed
(action), joint center will be lifted in the opposite direction (reac-
tion), and then the set lib will be in squeezed to the thick part of
yoke.

COMPONENTS
CAUTION:
Spiral cable may snap due to steering operation if steering column is separated from steering gear
assembly. Therefore fix steering wheel with a string to avoid turns.
REMOVAL
1. Set wheels in the straight-ahead position.
2. Remove undercover and tires from vehicle with power tool.
3. Remove front crossbar. Refer to FSU-8, "
Components" .
4. Confirm slit of lower joints fits with the projection on rear cover
cap, furthermore marking position on steering gear assembly
nearly fits with the projection on rear cover cap.
5. Remove cotter pin at steering outer socket, then loosen mount-
ing nut.
6. Use a ball joint remover (SST) to remove steering outer socket
from steering knuckle. Be careful not to damage ball joint boot.
CAUTION:
Tighten temporarily mounting nut to prevent damage to
threads and to prevent ball joint remover (SST) from com-
ing off.
7. Remove oil pipings (high pressure side and low pressure side)
from steering gear assembly, then drain fluid from pipings.
1. Cotter pin 2. Steering gear assembly 3. Rack mounting insulator
4. Rack mounting bracket

8. Loosen bolt on upper yoke of lower joint and remove bolt on
lower yoke of joint, then slide lower joint into lower shaft. Sepa-
rate steering gear assembly from lower shaft.
9. Tack bolt on upper yoke of lower joint, fix lower joint to lower
shaft.
10. Remove the fixing bolt and remove steering gear assembly, rack
mounting bracket and insulator from vehicle.
INSTALLATION

Refer to PS-17, "Removal and Installation" for tightening torque. Install in the reverse order of removal.
NOTE:
Refer to component parts location and do not reuse non-reusable parts.

After removing/installing or replacing steering components, check wheel alignment. Refer to FSU-6,
"Wheel Alignment Inspection" .

When steering wheel is set in the straight ahead direction, con-
firm slit of lower joint fits with the projection on rear cover cap,
furthermore marking position on steering gear assembly nearly
fits with the projection on rear cover cap.

After installation, bleed air from piping. Refer to PS-6, "Air
Bleeding Hydraulic System" .
