3) If steering wheel spokes are not horizontal when wheels
are set in the straight ahead position, and error is more
than 5°on the periphery of steering wheel, correctly re-in-
stall the steering wheel.

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.
11 Pipes(1) Damage to flared surface
(2) Damage to flare nut
