Alignment: Service and Repair

NOTICE: For Zero Point Calibration information, please refer to: TSB T-SB-0020-8 (3/25/08).


INSPECTION





1. MEASURE VEHICLE HEIGHT

Vehicle height:





2WD:





4WD:

Measuring points:
A: Ground clearance of spindle center
B: Ground clearance of front adjusting cam bolt center
C: Ground clearance of rear axle shaft center
D: Ground clearance of lower control arm front bushing center

NOTICE: Before inspecting the wheel alignment, adjust the vehicle height to the specification. If the vehicle height is not within the specification, try to adjust it by pushing down on or lifting the body.





2. INSTALL CAMBER-CASTER-KINGPIN GAUGE OR ONTO WHEEL ALIGNMENT TESTER
Follow the specific instructions of the equipment manufacturer.
3. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION





2WD:





4WD:

If the steering axis inclination is not within the specification, after the camber and caster have correctly adjusted, recheck the steering knuckle front wheel for bearing or looseness.

Measuring Point Reference:

4. INSPECT TOE-IN
If the toe-in is not within the specification, adjust the rack ends.





5. ADJUST CAMBER AND CASTER

NOTICE: After the camber has been adjusted, inspect the toe-in.

a. Loosen the front and/or rear adjusting cam nuts.
b. Adjust the camber and caster by front and/or rear adjusting cams. (See adjustment chart)

HINT: Try to adjust the camber and caster to the center value.

c. Torque the front and/or rear adjusting cam nuts.
Torque: 130 Nm (1,325 kgf.cm, 96 ft. lbs.)
6. ADJUST TOE-IN AND WHEEL ANGLE

HINT: First, check or adjust the lengths of the tie rod ends, then adjust the toe-in.

Tie rod end length left-right error: 1.5 mm (0.059 inch) or less





a. Remove the boot clamps.
b. Loosen the rack end lock nuts.
c. Turn the left and right rack ends an equal amount to adjust the toe-in.

HINT: Try to adjust the toe-in the center value.





d. Tighten the rack end lock nuts.
Torque: 55 Nm (560 kgf.cm, 41 ft. lbs.)
e. Place the boot on the seat and clip it.

HINT: Make sure that the boots are not twisted.








7. INSPECT WHEEL ANGLE
Turn the steering wheel fully, and measure the turning angle.
If wheel angle deviates from the specifications, readjust the toe-in and wheel angle within the specifications. At this time, the lengths of the tie rod end may be within less than 1.5 mm (0.059 inch).











8. HOW TO READ ADJUSTMENT CHART
a. Find the wheel alignment standard value applicable for the tire size.
b. Mark the selected standard value on the adjustment chart.
Example 2WD:
Camber -0 ° 15' (-0.25°)
Caster 3 ° 05' (3.08°)
c. Mark on the adjustment chart the alignment values measured at the vehicle height.
Example:
Camber 0 ° 00' (0°)
Caster 2 ° 15' (2.25°)
d. As shown in the illustration, read the distance from the standard value to the measured value, and adjust the front and/or rear adjusting cams accordingly.
Example:
Front cam - (shorter) 1.5
Rear cam + (Longer) 3.9
