CAUTION:
Clean steering gear assembly with kerosene before disassembling.
DISASSEMBLY
1.
Loosen outer socket lock nut, and then remove outer socket from inner socket.
2.
Remove boot clamps, and then remove boot from inner socket.
CAUTION:
Do not damage inner socket and gear housing assembly when removing boot. Inner socket and
gear housing assembly must be replaced if inner socket and gear housing assembly are damaged
because it may allow foreign material to enter.

3.
Remove inner socket from rack assembly while holding the flat portion of the rack next to the inner socket
using a suitable tool.
NOTE:
The flat portion is only located on rack tooth side of the rack assembly. Use the same flat portion when
removing both the LH and RH inner sockets.
4.
Measure adjusting screw height “H”, and loosen lock nut (2).
5.
Remove adjusting screw (1), retainer (3) and spring (4) from
gear housing assembly (5).
INSPECTION AFTER DISASSEMBLY
Joint Cover
Check joint cover protrusion for damage. Replace if there are.
Rack and Pinion Assembly
• Rotate rack and pinion assembly and check for torque variation or rattle. Replace steering gear as neces-
sary.
Gear Housing Assembly
Check gear housing assembly for damage or scratches. Replace steering gear as necessary.
Outer Socket and Inner Socket
1.
Check ball joint swinging torque.
• Hook a spring balance at the point shown 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.

STEERING GEAR
• Apply an axial load of 490 N (50 kg-f, 111 lb-f) to ball stud
using a dial gauge. Measure amount of stud movement, and
then make sure that the value is within the specified range.
Replace outer socket and inner socket if the measured value
is outside the standard.
ASSEMBLY
1.
Apply recommended grease to teeth part and bush part of rack assembly, if necessary.
2.
Apply recommended grease to back of rack assembly, if necessary.
3.
Install inner socket to rack assembly. Torque to specified value while holding the flat portion of the rack
next to the inner socket using a suitable tool.
4.
Apply recommended grease to inner socket. For application points, refer to "COMPONENT (R24K
TYPE)" .
5.
Decide on the neutral position for the rack assembly.
6.
Apply recommended grease to around retainer (3), then install
retainer (3), spring (4) and adjusting screw (1) to gear housing
assembly (5).
7.
Apply recommended thread locking sealant to the thread (2
turns thread), and then screw in the adjusting screw (1) until it
reaches height “H” from gear housing assembly (5) measured
before disassembling.
8.
Tighten lock nut to (2) the specified torque securing it to prevent
adjusting screw (1) from freewheeling condition.
9.
Move rack assembly 10 strokes throughout the full stroke so that
the parts can fit with each other.
10. Using Tools A and B, measure rotating torque of pinion assem-
bly. If the measurement is outside of the specified range, read-
just pinion rotating torque. If the measurement is outside of the
specified range for readjust, replace steering gear assembly.

11. Set dial gauge to the back of rack assembly on the pinion
assembly side around the center of stroke. Measure displace-
ment of rack under torsional torque of
±
7.8 N·m (0.80 kg-m, 69
in-lb), and then check if it is within the standard value. If the
measurement is outside the standard value, adjust it again. After
the readjustment, if measurement is still outside the standard
value, replace steering gear assembly.
12. Install boot to gear housing assembly and inner socket.
13. Install small diamter boot clamp.
14. Install large diameter boot clamp (1) to boot using Tool.
NOTE:
Install large diameter boot clamp (1) securely to boot groove,
and crimp it so as to have clearance of 3 mm (0.12 in) or less as
shown.
15. Install joint cover (1) to gear housing assembly (2).
CAUTION:
Install joint cover so that the protrusion for locating is
securely set to gear housing groove.
16. Adjust inner socket to standard length “L”, and then tighten lock
nut to the specified torque. Refer to "COMPONENT (R24K
TYPE)". Check length of inner socket “L” again after tightening
lock nut. Make sure that the length is the standard.
CAUTION:
Adjust toe-in. Refer to
. Length achieved after toe-in adjustment is not
necessarily the above value.
Standard value
: Less than 0.1 mm (0.004 in)
