D: ASSEMBLY
1) Insert combination switch to upper column shaft, and
install lower column cover with tilt lever held in the lowered
position. Then route ignition key harness and combination
switch harness between column cover mounting bosses.
2) Fit upper column cover to lower column cover, and
tighten combination switch and column cover.
Tightening torque:
1.2±0.2 N⋅m (0.12±0.02 kg-m, 0.9±0.1 ft-lb)
CAUTION:
Don’t overtorque screw.
E: INSTALLATION
1) Insert end of steering shaft into toe board grommet.
2) Tighten steering shaft mounting bolts under instrument
panel.
Tightening torque:
25±5 N⋅m (2.5±0.5 kg-m, 18.1±3.6 ft-lb)
3) Connect ignition and combination switch connectors
under instrument panel.
4) Connect airbag system connector at harness spool.
NOTE:
Make sure to apply double lock.
5) Install universal joint.
(1) Align bolt hole on the long yoke side of universal
joint with the cutout at the serrated section of shaft end,
and insert universal joint.
(2) Align bolt hole on the short yoke side of universal
joint with the cutout at the serrated section of gearbox
assembly. Lower universal joint completely.
(3) Temporarily tighten bolt on the short yoke side.
Raise universal joint to make sure the bolt is properly
passing through the cutout at the serrated section.
(4) Tighten bolt on the long yoke side, then that on the
short yoke side.
Tightening torque:
24±3 N⋅m (2.4±0.3 kg-m, 17.4±2.2 ft-lb)
CAUTION:

Make sure that universal joint bolts is tightened
through notch in shaft serration.

Excessively large tightening torque of universal
joint bolts may lead to heavy steering wheel operation.
Standard clearance between gearbox to DOJ:
Over 15 mm (0.59 in)
