REMOVAL
NOTE:
When reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned. This
will omit neutral position alignment procedure during spiral cable installation.
1. Set vehicle to the straight-ahead position.
2. Remove driver air bag module. Refer to SR-11, "
Removal and Installation".
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel with the steering wheel puller (A) [SST: ST27180001 (J-25726-A)].
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Never twist spiral cable freely on excessively after it becomes tight (doing so may cause the cable to
tear off).
NOTE:
Check the spiral cable neutral position after r eplacing or rotating spiral cable. Refer to SR-14, "
Removal and
Installation".

REMOVAL
1. Set vehicle to the straight-ahead position.
2. Fix the steering wheel.
3. Remove steering shaft fixing bolt and nut (lower joint side). CAUTION:
The steering shaft bellows are easily bent. N ever press the bellows too much with a tool.
4. Remove lower joint fixing bolt (steering gear side).
5. Remove lower joint from steering shaft and steering gear assembly. CAUTION:
 When removing lower joint, n ever insert a tool, such as a screw driver, into the yoke groove to
pull out the lower joint. In case of the violation of the above, replace lower joint with a new one.
 Spiral cable may be cut if steering wheel tu rns while separating steering column assembly and
steering gear assembly. Be sure to secure st eering wheel using string to avoid turning.
6. Turn carpet and remove the hole cover mounting nuts.
7. Remove the upper joint fixing bolt and nut (steering shaft side).

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.
