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.

INSPECTION AFTER REMOVAL
Lower Joint
 Check dust boot clamp (looseness and disconnection) and dust boot (scratches, cracks, and holes).
Replace the lower joint, as necessary.
 Check each part of lower joint for damage and other malfunctions. Replace if there is a malfunction.
Steering Shaft
 Check steering shaft and hole cover seal for scratches, cracks, and holes. Replace the stee\
ring shaft or hole
cover seal, as necessary.
 Check the sliding range of the steering shaft.
CAUTION:
Check the sliding range (A) (b etween the extended position
and the contracted position) of the steering shaft.
 Check the length (L) (extended posit ion) of the steering shaft.
