ST-98

< REMOVAL AND INSTALLATION >

[WITHOUT HEATED STEERING WHEEL]

STEERING GEAR AND LINKAGE

Bent cut end of the wire toward rack axial as shown in the figure
after twisting the wire 4 to 4.5 turns so that cut end does not con-
tact with boot.

19. Install cylinder tubes to gear housing assembly.

20. Install low pressure piping.

21. Adjust inner socket to standard length (L), and then tighten lock

nut (1) to the specified torque. Check length again after tighten-
ing lock nut.

CAUTION:

Adjust toe-in after this procedure. The length achieved after
toe-in adjustment is not necessary the above value.

INSPECTION AFTER DISASSEMBLY

Boot

Check boot for cracks, and replace it if a malfunction is detected.

Rack Assembly

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

Gear-Sub Assembly

• Check gear-sub assembly for damage or wear, and replace it if a malfunction is detected.
• Rotate gear-sub assembly 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

Check the following items and replace the component if it does not meet the standard.

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 speci-
fied value when ball stud and inner socket start to move. Replace
outer socket and inner socket if they are outside the standard.

BALL JOINT ROTATING TORQUE

Make sure that the reading is within the following specified range
using preload gauge (A) [SST: ST3127S000 (J-25765-A)]. Replace
outer socket if the reading is outside the specified value.

BALL JOINT AXIAL END PLAY

Apply an axial load of 490 N (50 kg, 110 lb) to ball stud. Using a dial
gauge, measure amount of stud movement, and then make sure that
the value is within the following specified range. Replace outer
socket (1) and inner socket (2) if the measured value is outside the
standard.

INSPECTION AFTER INSTALLATION

• Check if steering wheel turns smoothly when it is turned several times fully to the end of the left and right.
• Check the steering wheel play, neutral position steering wheel, steering wheel turning force, and front wheel

turning angle. Refer to

ST-80, "Inspection"

• Check the fluid level, fluid leakage, and air bleeding hydraulic system. Refer to

ST-78, "Inspection"
