Removal and InstallationBGS0003T
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 direction.
2. Remove driver air bag module. Refer to SRS-35, "
DRIVER AIR BAG MODULE" .
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel with the steering wheel puller [SST].
INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to PS-12, "COMPONENTS" .
NOTE:
Check the spiral cable neutral position after replacing or rotating spiral cable. Refer to SRS-38, "
INSTALLA-
TION" .
CAUTION:
Do not twist spiral cable freely on excessively after it becomes tight (doing so may cause the cable to
be turn off).

8. Remove fixing nut and bolt, then separate lower shaft from
steering column assembly (joint part).
9. Remove steering column assembly mounting nuts, then remove
steering column assembly from vehicle.
10. Loosen clamp, and then remove hole cover seal from hole
cover.
11. Remove mounting nuts of hole cover, and then remove clamp
and hole cover from dash panel.
12. Raise vehicle.
13. Remove fixing bolt of lower shaft, and then remove lower shaft
from vehicle.
INSPECTION AFTER REMOVAL

Check component parts for damage or other malfunctions. Replace if there are.

Measure the length L as shown in the figure if vehicle has been
involved in a minor collision. Replace steering column assembly
if outside the standard.

Measure steering column assembly rotating torque using pre-
load gauge [SST: ST3127S000]. Replace steering column
assembly if outside the standard.

INSTALLATION

Installation is the reverse order of removal. For tightening torque, refer to PS-12, "COMPONENTS" .

Install steering column assembly with tilt neutral condition to steering column assembly. Start installation
from vehicle front at this time.

When installing lower shaft 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 pinion assembly and measure the distance of inner socket, and
then measure the intermediate position of the distance.
–Align rear cover cap projection (A) with the marking position (B)
of gear housing assembly.
–Install slit part of lower shaft (C) aligning with the projection (A)
of rear cover cap (1). Make sure that the slit part of lower shaft
(C) is aligned with both the projection (A) of rear cover cap (1)
and the marking position (B) of gear housing assembly.
INSPECTION AFTER INSTALLATION
Make sure that steering wheel operates smoothly by turning several times from full left stop to full right stop.

DISASSEMBLY
1. Remove spring from jacket tube assembly and column mounting bracket.
2. Remove the TORX bolt (securing tilt lever), then remove tilt lever and adjusting nut from jacket tube
assembly.
3. Remove column mounting bracket from jacket tube assembly.
INSPECTION AFTER DISASSEMBLY

Check jacket tube assembly for deformation or damage. Replace if there are.

Check tilt mechanism components for malfunction. Replace if there are.
ASSEMBLY

Assembly is the reverse order of the disassembly. For tightening torque, refer to PS-15, "COMPONENTS"
.
