Removal and InstallationBGS0003T
REMOVAL
NOTE:
When reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned. This
will omit neutral position alignment procedure during spiral cable installation.
1. Set vehicle to the straight-ahead direction.
2. Remove driver air bag module. Refer to SRS-35, "
DRIVER AIR BAG MODULE" .
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel with the steering wheel puller [SST].
INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to PS-12, "COMPONENTS" .
NOTE:
Check the spiral cable neutral position after replacing or rotating spiral cable. Refer to SRS-38, "
INSTALLA-
TION" .
CAUTION:
Do not twist spiral cable freely on excessively after it becomes tight (doing so may cause the cable to
be turn off).

INSTALLATION

Installation is the reverse order of removal. For tightening torque, refer to PS-12, "COMPONENTS" .

Install steering column assembly with tilt neutral condition to steering column assembly. Start installation
from vehicle front at this time.

When installing lower shaft to steering gear assembly, follow the procedure listed below.
–Set rack of steering gear in the neutral position.
NOTE:
To get the neutral position of rack, turn pinion assembly and measure the distance of inner socket, and
then measure the intermediate position of the distance.
–Align rear cover cap projection (A) with the marking position (B)
of gear housing assembly.
–Install slit part of lower shaft (C) aligning with the projection (A)
of rear cover cap (1). Make sure that the slit part of lower shaft
(C) is aligned with both the projection (A) of rear cover cap (1)

INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to PS-17, "COMPONENTS" .

When installing lower shaft to steering gear assembly, follow the procedure listed below.
–Set rack of steering gear in the neutral position.
NOTE:
To get the neutral position of rack, turn pinion assembly and measure the distance of inner socket, and
then measure the intermediate position of the distance.
–Align rear cover cap projection (A) with the marking position (B)
of gear housing assembly.

(C) is aligned with both the projection (A) of rear cover cap (1)
and the marking position (B) of gear housing assembly.
–After installation, bleed air from the steering hydraulic system.
Refer to PS-39, "
HYDRAULIC LINE" .
–Perform final tightening of nuts and bolts on each part under
unladen conditions with tyres on level ground when removing
steering gear assembly. Check wheel alignment. Refer to FSU-
5, "Wheel Alignment Inspection" .
–Adjust neutral position of steering angle sensor after checking the wheel alignment for the models with
VDC. Refer to BRC-40, "

INSPECTION AFTER DISASSEMBLY
Boot
Check boot for cracks, and replace it if a malfunction is detected.
Rack Assembly
Check rack assembly for damage or wear, and replace it if a malfunction is detected.
Pinion Assembly

Check pinion assembly for damage or wear, and replace it if a malfunction is detected.

Rotate pinion and check for torque variation or rattle, and replace it if a malfunction is detected.
Gear Housing Assembly
Check gear housing assembly for damage and scratches (inner wall). Replace if there are.
Outer Socket and Inner Socket
1. Ball joint swinging torque

Hook a spring balance at the point shown in the figure and
pull the spring balance. Make sure that the spring balance
reads the specified value when ball stud and inner socket
start to move. Replace outer socket and steering gear assem-
bly if they are outside the standard.
2. Ball joint rotating torque

Make sure that the reading is within the following specified
range using the preload gauge [SST]. Replace outer socket if
the reading is outside the specified value.

a. Wrap an OHP sheet [approximately 70 mm (2.76 in) ×100 mm
(3.94 in)]. Around rack assembly teeth to avoid damaging rack
oil seal (inner). Install rack oil seal over sheet. Then, pull OHP
sheet along with rack oil seal until they pass rack assembly
teeth, and remove OHP sheet.
b. Insert rack oil seal (inner) into rack assembly piston (rack Teflon
ring).
c. Push retainer to adjusting screw side by hand, and move the
rack assembly inside the gear housing assembly so that the
rack oil seal (inner) can be pressed against the gear housing
assembly
d. Wrap an OHP sheet [approximately 70 mm (2.76 in) ×100 mm
(3.94 in)]. Around the edge to avoid damaging rack oil seal
(outer). Install rack oil seal over sheet. Then, pull oil seal along
with OHP sheet until they pass rack edge, and remove OHP
sheet.
e. Install end cover assembly to rack edge, and move rack oil seal
(outer) until it contacts with gear housing assembly.
5. Tighten end cover assembly to specified torque using a 45 mm
(1.77 in) open head (suitable tool).
CAUTION:
Do not damage rack assembly. Replace it if damaged
because it may cause fluid leakage.
6. Crimp gear housing assembly at one point using a punch as
shown in the figure so as to prevent end cover assembly from
getting loose after tightening end cover assembly.

7. Install pinion assembly to gear housing assembly.
CAUTION:
In order to protect rack oil seal from any damage, insert pinion assembly out straightly.
8. Apply recommended fluid to O-ring, and the install O-ring to rear cover.
9. Using a rear cover wrench [SST: KV489Q0030] (A), install rear
cover to gear housing assembly.
10. Decide on the neutral position for the rack.
11. Install rear cover cap to pinion assembly.
CAUTION:
Make sure that the projection of rear cover cap is aligned
with the marking position of gear housing assembly.
12. Apply recommended thread locking sealant to the thread (2
turns thread), and then screw in the adjusting screw until it
reaches height “H” from gear housing assembly measured
before disassembling.
13. Move rack assembly 10 strokes throughout the full stroke so that
the parts can fit with each other.
14. Measure pinion rotating torque within ±180° of neutral position
of the rack assembly using the preload gauge [SST] and preload
adapter [SST]. Stop the gear at the point where highest torque is
read.
15. Loosen adjusting screw and retighten to 5.4 N·m (0.55 kg-m, 48
in-lb), and then loosen by 20 to 40°.
