Alignment
NOTE:RZN140L: Regular Cab, Short Wheelbase with 2RZ-FE engine
RZN150L: Extra Cab, Extra Long Wheelbase with 2RZ-FE engine
VZN150L: Extra Cab, Extra Long Wheelbase with 5VZ-FE engine
INSPECTION
1. MEASURE VEHICLE HEIGHT
Vehicle Height:
Measuring points:
A: Ground clearance of spindle center.
B: Ground clearance of lower suspension arm bolt center.
C: Ground clearance of rear axle shaft center.
D: Ground clearance of leaf spring front hanger pin bolt center.
NOTICE: Before inspecting the wheel alignment, adjust the vehicle height to the specified value. If the vehicle height is not the specified value, try to adjust it by pushing down on or lifting the body.
2. INSTALL CAMBER-CASTER-KINGPIN GAUGE OR POSITION VEHICLE ON WHEEL ALIGNMENT TESTER
Follow the specific instructions of the equipment manufacturer.
3. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION
Camber, caster and steering axis inclination:
RZN140L Model
RZN150L Model
VZN150L Model
If the steering axis inclination is not within the specified value, after the camber and caster have been correctly adjusted, recheck the steering knuckle and front wheel for bearing or looseness.
4. ADJUST CAMBER AND CASTER
a. Loosen the upper suspension arm set bolts.
b. Adjust the camber and caster by adding or removing shims (See adjustment chart).
Shim Thickness:
HINT: Try to adjust the camber and caster to the center of the specified values.
c. How to read adjustment chart.
1. Find the wheel alignment standard value applicable for the particular model.
2. Mark the selected standard value on the adjustment chart.
Example:
Camber: 0°05' (0.08°)
Caster: 0°50' (0.83°)
3. Mark the alignment value measured when the vehicle was non-loaded on the adjustment chart.
Example:
Camber: 0°05' (0.08°)
Caster: 1°40' (1.67°)
4. As shown in the chart, read the distance from the measured value to the standard value, and adjust the front and/or rear shim thickness accordingly.
Example:
Front shim thickness: -1.7 mm (0.067 inch)
Rear shim thickness: +11.6 mm (0.063 inch)
d. Torque the upper suspension arm set bolts.
Torque: 130 Nm (1,300 kgf-cm, 94 ft. lbs.)
HINT: If the steering axis inclination is not as specified value after the camber and caster have been correctly adjusted, recheck the steering knuckle and front wheel for distortion or looseness.
NOTICE: Adjust the shim thickness to 7 mm (4-11 mm), and adjust the difference between the front and rear of the upper suspension arm shaft to within 4 mm.
Measuring Point Reference:
5. INSPECT TOE-IN
Toe-In:
If the toe-in is not within the specified value, adjust the rack ends.
6. ADJUST TOE-IN
a. Remove the 2 clips.
b. Loosen the tie rod end lock nuts.
c. Turn the right and left rack ends by an equal amount to adjust the toe-in.
HINT: Try to adjust the toe-in to the center of the specified value.
d. Make sure that the lengths of the right and left rack ends are the same.
Rack end length difference: 1.5 mm (0.059 inch) or less
e. Tighten the tie rod end lock nuts.
Torque: 54 Nm (550 kgf-cm, 40 ft. lbs.)
f. Place the boots on the seats and install the clips.
HINT: Make sure that the boots are not twisted.
7. INSPECT WHEEL ANGLE
Turn the steering wheel fully and measure the turning angle.
Wheel Turning Angle:
If the right and left inside wheel angles differ from the specified value, check the right and left rack end lengths.
HINT: If the rack ends lengths are not equal, the wheel turning angle cannot be adjusted properly. Reinspect the toe-in after adjusting the rack ends lengths.
