STEERING COLUMN
• When installing the steering column, finger-tighten all of the lower bracket and joint retaining bolts;
then tighten them to specification. Do not apply undue stress to the steering column.
• The lower nut on the upper joint may not be reused.
NOTE:
Align slit of the coupling joint with projection on dust cover. Insert the
joint until surface "A" contacts surface "B".
• After installation, turn steering wheel to make sure it moves
smoothly. Make sure the number of turns are the same from the
straight-forward position to left and right locks. Make sure that the
steering wheel is in a neutral position when driving straight ahead.
• When installing steering column to steering member, install mount-
ing nut from front side of vehicle.
INSPECTION AFTER INSTALLATION
• After installing steering column to vehicle, check tilt device operation range is within specification.
• Check if steering wheel operation can turn to the end of the left and
right stops smoothly.

DISASSEMBLY
1. Remove mounting bolt from upper joint, then remove upper joint from steering column assembly.
2. Remove ignition switch tamper resistant self-shear screws with a drill or other suitable tool.
ASSEMBLY
Assembly is in the reverse order of disassembly.
• Install new tamper resistant self-shear screws.
NOTE:
Any time the ignition switch has been removed and installed, the
keys must be re-registered in the BCM. Refer to CONSULT-II opera-
tion manual IVIS/NVIS.
INSPECTION AFTER ASSEMBLY
When the steering wheel does not turn smoothly, check the steering column as follows:
1. Check the column bearings for damage or unevenness. Lubricate with recommended multi-purpose
grease. Replace the steering column as an assembly, if necessary.
2. Check the column tube for deformation or breakage. Replace the steering column as an assembly, if nec-
essary.
