E: INSPECTION
1. BASIC INSPECTION
1) Clean all the disassembled parts, and check for wear, damage or any other faults, then repair or replace
as necessary.
2) When disassembling, check the inside of gearbox for water. If any water is found, carefully check the 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
1Input shaft(1) Bent input shaft
(2) Damage on serration
If the bend or damage is excessive, replace the entire
gearbox.
2Dust seal(1) Crack or damage
(2) Wear
If the outer wall slips, the lip is worn out or damage is
found, replace it with a new one.
3Rack & pinion Poor mating of rack with pinion
(1) Adjust the backlash properly.
By measuring the turning torque of the gearbox and slid-
ing resistance of rack, check if the rack & pinion engage
uniformly and smoothly with each other. (Refer to “Ser-
vice limit”.)
(2) Pull out the entire rack to allow viewing of the teeth,
and check for damage.
Even if abnormality is found in either (1) or (2), replace
the entire gearbox.

(1) Bending of the rack shaft
(2) Bending of the cylinder portion
(3) Crack or damage on the cast
iron portion
Replace the gearbox with a new one.
(4) Wear or damage on rack bush-
ing
If the free play of rack shaft in radial direction is out of the
specified range, replace the gearbox with new one. (Refer
to “Service limit”.)
(5) Wear on input shaft bearing
If the free play of input shaft in radial and axial direction is
out of the specified range, replace the gearbox with a new
one. (Refer to “Service limit”.)

C: INSPECTION
Check all disassembled parts for wear, damage or other problems. Repair or replace the defective parts as
necessary.
CAUTION:
Although the surface layer materials of rubber hoses have excellent weathering resistance, heat re-
sistance and resistance for low temperature brittleness, they are likely to be damaged chemically by
brake fluid, battery electrolyte, engine oil and automatic transmission fluid and their service lives are
to be very shortened. Wipe off hoses immediately if any of these come into contact with the hoses.
Since resistances for heat or low temperature brittleness are gradually declining according to time
accumulation of hot or cold conditions for the hoses and their service lives are shortening accord-
ingly, it is necessary to perform careful inspection frequently when the vehicle is used in hot weather
areas, cold weather areas and a driving condition in which many steering operations are required in
short time.
Particularly continuous work of relief valve over 5 seconds causes to reduce service lives of the hos-
es, the oil pump, the fluid, etc. due to over heat.
