Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Section 510 (Front Wheel Alignment): Inspection
- MEASURE VEHICLE HEIGHT (See SUSPENSION & AXLE SPECIFICATIONS
)
Measuring points:
A: Ground clearance of the front drive shaft center
B: Ground clearance of the front adjusting cam bolt center
C: Ground clearance of the rear axle shaft center
D: Ground clearance of the leaf spring front side bushing center
Vehicle height:
Front: A - B
Rear: C - D
NOTE: 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.
- INSTALL CAMBER-CASTER-KINGPIN GAUGE OR POSITION VEHICLE ON WHEEL ALIGNMENT TESTER
Follow the specific instructions of the equipment manufacturer.
- INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION (See SUSPENSION & AXLE SPECIFICATIONS
)
If the steering axis inclination is not within the specified value, after the camber and caster have been correctly adjusted, re-check the steering knuckle and front wheel for bearing or looseness.
- ADJUST CAMBER AND CASTER
- Loosen the front and/or rear adjusting cam set bolts.
- 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 of the specified values.
- How to read adjustment chart (Example).
- Find the applicable wheel alignment standard value for the particular model.
- Mark the selected standard value on the adjustment chart.
Example:
Camber: 0°10' (0.17°)
Caster: 3°00'
- Measure the present wheel alignment value with the vehicle in non-loaded condition.
- Mark the measured present value on the adjustment chart.
Example:
Camber: 0°30' (0.50°)
Caster: 2°40' (2.67°)
- As shown in the example chart, read the distance from the measured value to the standard value, and adjust the front and/or rear adjusting cams accordingly.
Amount to turn adjusting cams (by graduation):
Example:
Front cam: 1.3 (+) Direction
Rear cam: 3.3 (+) Direction
