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)

C: INSPECTION
1) Clean all disassembled parts, and check for wear,
damage, or any other faults, then repair or replace as nec-
essary.
2) When disassembling, check inside of gearbox for water.
If any water is found, carefully check boot for damage,
input shaft dust seal, adjusting screw and boot clips for
poor sealing. If faulty, replace with new parts.
No. Parts Inspection Corrective action
1 Input shaft(1) Bend of input shaft
(2) Damage on serrationIf bend or damage is excessive, replace
entire gearbox.
2 Dust seal(1) Crack or damage
(2) WearIf outer wall slips, lip is worn out or
damage is found, replace it with new one.
3 Rack and pinion Poor mating of rack with pinion(1) Adjust backlash properly.
By measuring turning torque of
gearbox and sliding resistance of rack,
check if rack and pinion engage
uniformly and smoothly with each
other.
(Refer to“Service limit”.)
(2) Keeping rack pulled out all the way so
that all teeth emerge, check teeth for
damage.
Even if abnormality is found in either
(1) or (2), replace entire gearbox.
4 Gearbox unit(1) Bend of rack shaft
(2) Bend of cylinder portion
(3) Crack or damage on cast iron portionReplace gearbox with new one.
(4) Wear or damage on rack bushIf free play of rack shaft in radial direction
is out of the specified range, replace
gearbox with new one. (Refer to“Service
limit”.)
(5) Wear on input shaft bearingIf free plays of input shaft in radial and
axial directions are out of the specified
ranges, replace gearbox with new one.
(Refer to“Service limit”.)
5 Boot Crack, damage or deterioration Replace.
6 Tie-rod(1) Looseness of ball joint
(2) Bend of tie-rodReplace.
7 Tie-rod end Damage or deterioration on dust seal Replace.
8 Adjusting screw spring Deterioration Replace.
9 Boot clip Deterioration Replace.
10 Sleeve Damage Replace.
