DRIVE BELTINSPECTIONINSPECT DRIVE BELT(a) Visually check the belt for excessive wear, frayed cords,
etc.If any defect is found, replace the drive belt.HINT:Cracks on the rib side of a belt are considered acceptable. Re-place the belt if there are any missing ribs.
HINT:� After installing a belt, check that it fits properly in the
ribbed grooves.� Check with your hand to confirm that the belt has not
slipped out of the groove on the bottom of the pulley.

INSPECTION1. CHECK FLUID LEVEL(a) Keep the vehicle level.(b) With the engine stopped, check the fluid level in the reser-
voir.If necessary, add fluid.
Fluid: ATF DEXRON ® II or IIIHINT:When the fluid is hot, check that the fluid level is within the HOTrange.If the fluid is cold, check that it is within the COLD range.(c) Start the engine and run at idle.(d) Turn the steering wheel from lock to lock several times to
raise fluid temperature.Fluid temperature: 80 °C (176°F)
(e) Check for foaming or emulsification.If foaming or emulsification is identified, bleed air from the pow-er steering system (See page SR-4 ).
(f) With the engine idling, measure the fluid level in the reser-voir.
(g) Stop the engine.(h) Wait a few minutes and remeasure the fluid level in the
reservoir.Maximum fluid level rise: 5 mm (0.20 in.)
If the fluid level rise exceeds the maximum, bleed air from thepower steering system (See page SR-4 ).(i) Check the fluid level.

INSPECTION1. MEASURE OIL CLEARANCE BETWEEN VANE PUMP
SHAFT AND BUSHINGUsing a micrometer and a caliper gauge, measure the oil clear-ance.
Maximum clearance: 0.07 mm (0.0028 in.)If it is more than the maximum, replace the vane pump assem-bly.
2. INSPECT VANE PUMP ROTOR AND VANE PLATES(a) Using a micrometer, measure the thickness of the 10
vane plates.Standard thickness:1.405 to 1.411 mm (0.05531 to 0.05555 in.)
(b) Using a feeler gauge, measure the clearance between aside face of the vane pump rotor groove and the vaneplate.Maximum clearance: 0.03 mm (0.0012 in.)
If it is more than the maximum, replace the vane pump assem-bly.
3. INSPECT FLOW CONTROL VALVE(a) Coat the flow control valve with power steering fluid and
check that it falls smoothly into the valve hole of the fronthousing under its own weight.
If it lacks smoothness, replace the vane pump assembly.
(b) Check the flow control valve for leakage. Close one of theholes and apply compressed air of 392 to 490 kPa (4 to5 kgf/cm2, 57 to 71 psi) into the opposite side hole, andconfirm that air does not come out from the end hole.
If air leaks, replace the vane pump assembly.

4327Author�: Date�:
STEERING SYSTEMPRECAUTION� Care must be taken to replace parts properly because they could affect the performance of the
steering system and result in a driving hazard.� The TOYOTA TUNDRA is equipped with an SRS (Supplemental Restraint System) such as the
driver airbag and front passenger airbag. Failure to carry out service operation in the correctsequence could cause the SRS to unexpectedly deploy during servicing, possibly leading toa serious accident. Before servicing (including removal or installation of parts, inspection orreplacement), be sure to read the precautionary notices in the RS section.
� When replacing the steering angle sensor, drive the vehicle straight ahead at a speed of 6.5 mph(10.5 km/h) or more. Accordingly, zero point calibration of the steering angle sensor is per-formed.
� After performing ”Front wheel alignment adjustment”, clearing and reading the yaw rate & de-celeration sensor zero point calibration data is necessary (See page DI-1494 ).

and check the steering wheel free play.Maximum free play: 30 mm (1.18 in.)
2. CHECK STEERING EFFORT(a) Center the steering wheel.(b) Remove the steering wheel pad
(See page SR-18 , SR-33 ).(c) Start the engine and run at idle.(d) Measure the steering effort in both directions.
Steering effort (Reference):4.9 N·m (50 kgf·cm, 43 in.·lbf)
HINT:Check tire type, pressure and contact surface before makingyour diagnosis.(e) Tighten the steering wheel set nut.

1. INSPECT STEERING WHEEL OFF CENTER(a) Apply masking tape on the top center of the steering
wheel and steering column upper cover.
(b) Drive the vehicle in a straight line for 100 meters at aconstant speed of 35 mph (56 km/h), and hold the steer-ing wheel to maintain the course.
(c) Draw a line on the masking tape as shown in the illustra-tion.

(d) Turn the steering wheel to its straight position.HINT:Refer to the upper surface of the steering wheel, steering spokeand SRS airbag line for the straight position.(e) Draw a new line on the masking tape of the steering wheel
as shown in the illustration.(f) Measure the distance between the 2 lines on the masking
tape of the steering wheel.(g) Convert the measured distance to steering angle.
Measured distance 1 mm (0.04 in.) = Steering angleapproximately 1 deg.
HINT:Make a note of the steering angle.2. ADJUST STEERING ANGLE(a) Lift up the vehicle.NOTICE:The adjustment method for steering angle is different de-pending on the models. Check whether it is type A or B.(b) Draw a line on the RH and LH tie rod and rack ends where
it can easily be seen.(c) Using a paper gauge, measure the distance from RH and
LH tie rod ends to the rack end screws.HINT:� Measure the RH side and LH side.� Make a note of the measured values.
(d) Remove the RH and LH boot clips from the rack boots.(e) Loosen the RH and LH lock nuts.(f) Turn the RH and LH rack end by the same amount (but
in different directions) according to the steering angle.1 turn 360 deg. of rack end (1.5 mm (0.059 in.) horizon-tal movement) = 12 deg. of steering angle
(g) Tighten the RH and LH lock nuts by the specified torque.Torque: 55 N·m (560 kgf·cm, 41 ft·lbf)
NOTICE:Make sure that the difference in length between RH and LHtie rod ends and rack end screws are within 1.5 mm (0.059in.).(h) Install the RH and LH boot clips.
