Rear Wheel Alignment
INSPECTION1. Measure rear vehicle height. Refer to "Front Wheel Alignment" for vehicle height information.
NOTICE: Before inspecting the wheel alignment, adjust the vehicle height to specification.
2. Install camber-caster-kingpin gauge onto wheel alignment tester. Follow the specific instructions of the equipment manufacturer.
3. Inspect camber.
Camber:
- Coil Suspension: -0°50' ± 45' (-0.83° ± 0.75°)
Left-Right error: 30' (0.5°) or less
- Air Suspension: -1°25' ± 45' (-1.42° ± 0.75°)
Left-Right error: 30' (0.5°) or less
Measuring Point Reference:
4. Inspect toe-in.
Coil Suspension:
- A + B: 0°12' ± 12' (0.2° ± 0.2°)
- C - D: 3 ± 2 mm (0.12 ± 0.08 inch)
Air Suspension:
- A + B: 0°18' ± 12' (0.3° ± 0.2°)
- C - D: 3 ± 2 mm (0.12 ± 0.08 inch)
5. Adjust camber and toe-in.
a. Measure the length of the lower suspension arm No. 1 and No. 2, as shown in the illustration.
Length: (E - F) or (F - E) should be less 4.0 mm (0.16 inch). If it is not within the specification, adjust the length of the arms by turning the adjusting cam, as shown, until (E - F) or (F - E) is less than 4.0 mm (0.16 inch).
b. Measure the camber and toe-in. If the camber and toe-in are still not within the specification, adjust the camber and toe-in with the adjusting cam. (See adjustment chart).
c. Loosen the front and/or rear cams.
d. Adjust camber and toe-in by turning the front and/or rear cams.
e. Torque the front and/or rear cam nuts to 78 Nm (57 ft. lbs.)
6. How to read adjustment chart.
a. Mark on the graph the measurements taken from the vehicle.
Example (Coil suspension):
Camber (LH) -1°05' (-1.08°)
Camber (RH) -0°20' (-0.33°)
Toe-in (total) (out) 2 mm (0.08 inch)
b. As shown the illustration, from the graph the amounts by which the front and/or rear cam are to be adjusted. Amount to turn adjusting cam (by graduation):
LH Front cam - (Shorter) 1.2
LH Rear cam - (Shorter) 0.7
RH Front cam + (Longer) 1.8
RH Rear cam+ (Longer) 2.3
