Removal and InstallationEDS00052
REMOVAL
1. Put mating marks onto propeller shaft flange yoke and final drive and transfer companion flanges.
CAUTION:
Use paint to avoid scratching the surface.
2. Remove mounting nuts and remove exhaust tube insulator from vehicle.
3. Loosen mounting nuts of center bearing mount brackets (front and rear).
CAUTION:
Tighten nuts temporarily.
4. Remove mounting nuts and bolts from propeller shaft companion flanges, transfer, and final drive.
Remove mounting nuts securing center bearing brackets (front and rear) onto vehicle. Then remove pro-
peller shaft from vehicle.
CAUTION:
If constant velocity joint was bent during propeller shaft assembly removal, installation, or trans-
portation, its boot may be damaged. Wrap boot interference area to metal part with shop cloth or
rubber to protect boot from breakage.
INSPECTION AFTER REMOVAL
1. As shown in the figure, while fixing yoke on one side, check axial
play of joint. If outside the standard, replace propeller shaft
assembly.
2. Check propeller shaft for bend and damage. If damage is
detected, replace propeller shaft assembly.
3. Check center bearing for abnormal noise and damage. If noise
or damage is detected, replace propeller shaft assembly.
CAUTION:
lCenter bearings (front and rear) cannot be disassem-
bled.
lJoints cannot be disassembled.
INSTALLATION
Paying attention to following items, install in the reverse order of removal.
lAlign mating marks to install propeller shaft, and tighten to specified torque.

REMOVAL
1. Remove cotter pin, and loosen mounting nut. Remove tie rod from steering knuckle with a pitman arm
puller.
CAUTION:
lBe careful not to damage dust boot at ball joint of tie rod.
lBefore using pitman arm puller (multi-purpose tool), loosely tighten nut for temporary holding.
2. Mark lower joint and steering gear with paint for easy installation. Remove pinch bolt from gear side of
lower joint.
3. Remove high pressure-side tube and low pressure-side hose of hydraulic piping from steering gear.
4. Remove mounting nuts on upper portion of stabilizer connecting rod and stabilizer clamp mounting bolts.
Move stabilizer toward vehicle front.
5. Remove steering gear assembly mounting bolts and nuts. Remove power steering tube bracket and
steering gear assembly from suspension member.
6. Tilt steering gear to prevent any contact with other parts. Then remove it from right side of vehicle.
INSTALLATION
Paying attention to following items, install in the reverse order of removal.
lAfter installation, bleed air. Refer toPS-5, "Bleeding Hydraulic System".
lRemove mounting bolt and nut from upper portion of lower joint. This will facilitate installation of lower joint
to steering gear. Then slide lower joint in place.
lCheck lower slit of lower joint is engaged with projection on rear
cover cap. Install pinch bolt for lower portion of lower joint.
Check steering gear is in straight-ahead position. Also check
rear cover is in position shown in figure. Then install lower joint
to steering gear.

Disassembly and AssemblyEGS0004K
DISASSEMBLY
1. To disassemble and assemble power steering gear, fix steering
gear mount flange in a vise with copper plates.
CAUTION:
lClean steering gear with kerosene. Be careful to avoid
splashing or applying any kerosene over connector of
discharge port or return port.
lAlways replace O-rings, oil seals, and copper washes
with new ones.
2. Loosen and remove adjusting screws and lock nuts.
3. Remove rear housing mounting bolts to remove gear sub
assembly.
CAUTION:
Do not disassemble rear housing and pinion gear assem-
bly.
4. Remove tie rod outer socket and boot.
5. Remove spacer ring on lock plate. Move it to rack side to expose
crimping of lock plate.
CAUTION:
lDo not reuse boot, spacer ring, and lock plate.
lWhen removing boot, do not damage boot mounting
grooves by tool. If it damaged, it may cause oil leak.
Replace tie rod inner socket and gear housing assembly.
lWhen removing lock plate from rack, avoid damaging
surface of rack. If damaged, rack assembly must be
replaced. Otherwise, oil leaks will result.
6. Raise crimping areas (2) (A) of lock plate. Loosen inner socket and remove from rack.

aged, rack assembly must be replaced. Otherwise, oil leaks
will result.
9. Pull rack assembly with rack seal out of gear housing assembly.
CAUTION:
When pulling out rack assembly, do not damage cylinder
inner wall. If it damaged, it may cause oil leak. Replace gear
housing assembly.
10. Heat Teflon ring to approx. 40°C (104°F) with a hot air blower Remove it and O-ring from rack. Be careful
not to damage rack.

23. Using a preload gauge, measure rotational torque of pinion gear.
Check that reading is within range specified. If reading is outside
specification, readjust rack. If reading is still outside specifica-
tion, replace power steering gear.

fully to left.
25. Set dial gauge as shown in figure. Measure vertical movement
of rack when pinion is turned counterclockwise with torque of 4.9
N·m (0.5 kg·m,43in·lb). Check reading is within range specified.
If reading is outside of specification, readjust rack. If reading is
still outside of specification, replace power steering gear.

(stainless wire).
b. Wrap clamp around boot groove for two turns. Insert screwdriv-
ers in loops on both ends of wire. Twist 4 to 4.5 turns while pull-
ing them with force of approx. 98 N (10 kg,22.1 lb).Rotational torque
