STEERING POWER STEERING FLUID
1996 LAND CRUISER (RM451U)
INSPECTION
1. CHECK FLUID LEVEL
(a) Keep the vehicle level.
(b) With the engine stopped, check the fluid level in the oil reservoir.
If necessary, add fluid.
Fluid: ATF DEXRON® II or III
HINT:
Check that the fluid level is within the HOT LEVEL range on the
reservoir cap dipstick. If the fluid is cold, check that it is within
the COLD LEVEL range.
(c) Start the engine and run it at idle.
(d) Turn the steering wheel from lock to lock several times to
boost fluid temperature.
Fluid temperature: 80° C (176°F)
(e) Check for foaming or emulsification.
If there is foaming or emulsification, bleed power steering sys-
tem. (See page SR−3 ).
(f) With the engine idling, measure the fluid level in the oil reservoir.
(g) Stop the engine.
(h) Wait a few minutes and remeasure the fluid level in the oil reservoir.
Maximum fluid level rise: 5 mm (0.20 in.)
If a problem is found, bleed power steering system (See page
SR−3 ).
(i) Check the fluid level.

2. CHECK STEERING FLUID PRESSURE
(a) Disconnect the pressure feed tube from the PS vane
pump (See page SR−23).
(b) Connect SST over 2 new gaskets, as shown below. SST 09640 −10010 (09641 −01010, 09641 −01030,
09641 −01060)
NOTICE:
Check that the valve of the SST is in the open position.
(c) Bleed the power steering system (See page SR−3).
(d) Start the engine and run it at idle.
(e) Turn the steering wheel from lock to lock several times to
boost fluid temperature.
Fluid temperature: 80° C (176°F)
(f) With the engine idling, close the valve of the SST and ob-
serve the reading on the SST.
Minimum fluid pressure:
9,316kPa (95 kgf/cm
2, 1,351 psi)
NOTICE:
Do not keep the valve closed for more than 10 se-
conds.
Do not let the fluid temperature become too high.

STEERING WHEEL
INSPECTION
1. CHECK STEERING WHEEL FREEPLAY
(a) With the vehicle stopped and tires pointed straight ahead,
rock the steering wheel gently back and forth with light fin-
ger pressure.
(b) Freeplay should not exceed the maximum. Maximum freeplay: 40 mm (1.58 in.)
If the freeplay exceeds the maximum, adjust it in the following
procedure.
2. ADJUST STEERING GEAR
(a) Point the front wheels straight ahead.
(b) Loosen the adjusting screw lock nut.
(c) Turn the cross shaft adjusting screw clockwise to de- crease steering wheel freeplay and counterclockwise to
increase it.
HINT:
Turn the adjusting screw in small increments and check the
freeplay between each adjustment.
(d) Turn the steering wheel half way around in both direc- tions.
(e) Check that the freeplay is correct and steering is smooth and without rough spots.
(f) Torque the adjusting screw lock nut (See page SR−41).
3. CHECK STEERING EFFORT
(a) Center the steering wheel.
(b) Remove the steering wheel pad (See page SR−11).
(c) Start the engine and run it at idle.
(d) Measure the steering effort in both directions.

6. INSTALL PITMAN ARM
(a) Align the alignment marks on the pitman arm and the
cross shaft, and install the spring washer and set nut.
Torque: 177 N·m (1,800 kgf·cm, 130 ft·lbf)
(b) Connect the pitman arm to the relay rod assembly.
(c) Torque the nut. Torque: 91 N·m (925 kgf·cm, 67 ft·lbf)
(d) Install a new cotter pin.
7. INSTALL ENGINE UNDER COVER
Tighten the 4 bolts.
8. CHECK FRONT WHEEL ALIGNMENT (See page SA−4 )

INSPECTION
1. INSPECT SHIFT LEVER POSITION
(a) Start the engine, and turn the center diff lock switch to
OFF.
(b) Check that the center diff indicator light comes on when the transfer shift lever shifted to the ”L” position. Check
that the light goes off when the lever is shifted to the ”N”
or ”H” position.
2. INSPECT CENTER DIFF LOCK CONTROL RELAY
(a) Check that there is continuity between the terminals, as shown in the chart.
HINT:
There is a diode between the terminals 6 and 7. If the circuit
shown no continuity, change the positive (+) and negative ( −)
probes and recheck the circuit.
(b) Apply battery positive voltage between the terminals and check that there is continuity between the terminals, as
shown in the chart.
If continuity is not as specified, replace the relay.
