SULT-II. (Malfunction is present in the 4WD system.)
2. CHECK USING THE DATA MONITOR FUNCTION OF THE CONSULT- II.
●Perform inspection by the data monitor function of the CONSULT-II.
●Check that the operation is in AUTO mode.
●Measure voltage when the accelerator pedal is not depressed. (Accelerator pedal not depressed: approx.
0.5V or lower)
●Measure the current supplied to the 4WD solenoid valve. (Accelerator pedal not depressed: approx. 0A)
OK or NG
OK >> GO TO 3. (No self-diagnosis malfunction indicated.)

On-Vehicle Inspection and Service
EES00072
LOOSENESS, BACKLASH AND DAMAGE OF MOUNTING PARTS AND CONNECTIONS
Lift vehicle and inspect the following:
●Check mounting point of each component for looseness, backlash and damage.
●Check lower ball joint end play.
1. Attach a dial gauge so that the contact rests on the brake caliper.
2. Set front wheels in a straight-ahead position. Do not depress brake pedal.
3. Measure axial endplay by placing an iron pry bar or something similar between transverse link and steer-
ing knuckle.
CAUTION:
Be careful not to damage ball joint boot.
4. If axial endplay is outside the standard, remove transverse link and check lower ball joint.
Wheel AlignmentEES00073
DESCRIPTION
●Measure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, coolant, and
lubricant are full. However, spare tire, jack, and hand tools should be unloaded.
PRELIMINARY INSPECTION
1. Check the tires for improper air pressure and wear.
2. Check road wheels for runout.
3. Check wheel bearing axial endplay.
4. Check lower ball joint axial endplay.
5. Check strut operation.
6. Check each mounting point of axle and suspension for looseness and deformation.
7. Check each link and arm for cracks, deformation, and other damage.
8. Check the vehicle posture.
INSPECTION OF CAMBER, CASTER, AND KINGPIN INCLINATION ANGLES
● Camber, caster, and kingpin inclination angles cannot be adjusted.
●Before inspection, mount front wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so the vehicle will remain horizontal.
1. Measure camber, caster and kingpin inclination of both right and
left wheels with a suitable alignment gauge.
2. If camber, caster or kingpin inclination is not within specification,
inspect front suspension parts. Replace dam-aged or worn out
parts.
1. Upper mounting plate 2. Strut spacer 3. Strut mounting insulator
4. Spring upper seat 5. Thrust bearing 6. Spring upper seat
7. Upper rubber seat 8. Bound bumper 9. Coil spring

Measure toe-in using the following procedure.
WARNING:
●Always perform the following procedure on a flat surface.
●Make sure that no person is in front of the vehicle before
pushing it.
1. Bounce front of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of tread (rear side) of both tires at the
same height as hub center. These are measuring points.
4. Measure distance “A” (rear side).
5. Push the vehicle slowly ahead to rotate the wheels 180degrees
(1/2 turn).
If the wheels have rotated more than 180 degrees (1/2 turn), try the
above procedure again from the beginning. Never push vehicle
backward.
6. Measure distance “B” (front side).
STEERING ANGLE INSPECTION
1. Set wheels in straight-ahead position. Move vehicle to set front wheels on turning radius gauge.
2. Turn steering wheel fully to right and left, and measure steering angle. Refer to PS-36, "

Removal and InstallationEES00074
REMOVAL
1. Remove tires. Remove brake caliper and hung it aside.
CAUTION:
Avoid depressing brake pedal with brake caliper removed.
2. Remove electrical wires of ABS wheel speed sensor from strut.
3. Remove brake hose lock plate.
4. Remove mounting bolts and nuts securing steering knuckle to strut.
5. Remove mounting nuts on upper mounting plate and remove upper mounting plate and strut from vehicle.
INSTALLATION
●Refer to FSU-5, "Components" in “Front Suspension Assembly” for tightening torque. Tighten in the
reverse order of removal.
●Be sure arrows on strut mount insulator and spring upper seat
are positioned as shown. Also be sure notch in strut spacer is
positioned as shown. Then install strut.
●Assemble upper mounting plate with its notch facing toward the
outside.
Disassembly and AssemblyEES00075
DISASSEMBLY
1. Install strut attachment to strut and fix it in a vise.
CAUTION:
When installing strut attachment, wrap a shop cloth around
strut to protect it from damage.
2. Slightly loosen piston rod lock nut.
WARNING:
Do not remove piston rod lock nut completely. If it is
removed completely, coil spring jumps out and may cause
serious damage or injury.
3. Compress coil spring using a spring compressor.
WARNING:
Make sure that the pawls of the two spring compressors are firmly hooked on the spring. The
spring compressors must be tightened alternately so as not to tilt the spring.
4. After making sure coil spring is free between upper and lower seats after Step 3. Remove piston rod lock
nut.
5. Remove small parts on strut.
●Remove strut spacer, strut mount insulator, thrust bearing, spring upper seats, and upper rubber seats.
Then remove coil spring.
6. Remove bound bumper from spring upper seat.
7. Gradually release spring compressor, and remove coil spring.
INSPECTION AFTER DISASSEMBLY
Strut
●Check strut for deformation, cracks, and damage, and replace if necessary.
●Check piston rod for damage, uneven wear, and distortion, and replace if necessary.
●Check welded and sealed areas for oil leakage, and replace if necessary.
