STEERING SHAFT
8. Remove the steering shaft from upper joint by sliding the steer-ing shaft (A: sliding range).
9. Remove the steering shaft and hole cover.
10. Remove collar, hole cover seal, and hole cover assembly. CAUTION:
Never damage hole cover seal.
11. Perform inspection after removal. Refer to ST-39, "
Inspection".
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Spiral cable may be cut if steering wheel turns while separating steering column assembly and steer-
ing gear assembly. Be sure to secure steer ing wheel using string to avoid turning.
Insert hole cover seal all the way to the hole cover. CAUTION:
Never damage the seal lip of the hole cover seal with the tip of the steering shaft.
Install clamp as shown in the figure.
Tighten the clamp to the spec ified torque and check the clamp
length (A).
After tightening the upper joint fixing bolt and nut, check the no clearance between bolt and steering shaft.
CAUTION:
Never reuse upper joint mounting nut.
When installing lower joint, tighten the steering gear side fixing bolt
first.
When installing lower joint to steering gear assembly, follow the procedure listed below.
- Set rack of steering gear in the neutral position. NOTE:
To get the neutral position of rack, turn gear-sub as sembly and measure the distance of inner socket, and
then measure the intermediate position of the distance.

Hook a spring balance at the point shown in the figure and pull the spring balance. Make sure that the spring balance reads the spec-
ified value when ball stud and inner socket start to move. Replace
outer socket and inner socket if they are outside the standard.
BALL JOINT ROTATING TORQUE
Make sure that the reading is within the following specified rangeusing preload gauge (A) [SST: ST3127S000 (J-25765-A)]. Replace
outer socket if the reading is outside the specified value.
BALL JOINT AXIAL END PLAY
Apply an axial load of 490 N (50 kg, 110 lb) to ball stud. Using adial gauge, measure amount of stud movement, and then make
sure that the value is within the following specified range. Replace
outer socket (1) and inner socket (2) if the measured value is out-
side the standard.
INSPECTION AFTER INSTALLATION
After installation, bleed air from the steering hydraulic system. Refer to ST-30, "Inspection".
Check if steering wheel turns smoothly when it is turned several times fully to the end of the left and right.
Check the steering wheel play, neutral position steeri ng wheel, steering wheel turning force, and front wheel
turning angle. Refer to ST-32, "
Inspection".
Check the fluid level, fluid leakage, and air bleeding hydraulic system. Refer to ST-30, "
Inspection".
Perform final tightening of nuts and bolts on each part under unladen conditions with tires on level ground when removing steering gear assembly. Check wheel alignment. Refer to FSU-7, "
Inspection".
Adjust neutral position of steering angle sensor after checking wheel alignment. Refer to BRC-64, "
Work
