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.

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" .
