PROCEDURE
1. INSPECT TIRES
(a) Inspect the tires for wear and proper inflation pressure.

2. MEASURE VEHICLE HEIGHT
NOTICE:
- Before inspecting the wheel alignment, adjust the vehicle height to the specified value.
- Be sure to perform measurement on a level surface.
- If it is necessary to go under the vehicle for measurement, confirm that the parking brake is applied and the vehicle is secured with chocks.
- Inspect while the vehicle is unloaded.
- The standard value shown here is a value that is used for performing a wheel alignment and does not indicate the height of an actual vehicle.
(a) Bounce the vehicle up and down at the corners to stabilize the suspension.
(b) Measure the vehicle height.
Measurement Points:
- A: Ground clearance of front wheel center
- B: Ground clearance of center of bolt head of front lower No. 2 suspension arm bushing (rear bolt of front lower No. 1 suspension arm sub-assembly).
- C: Ground clearance of rear wheel center
- D: Ground clearance of center of tip of threaded portion of rear lower No. 2 suspension arm assembly and rear suspension member sub-assembly.

|
(b) Remove the 2 nuts on the lower side of the front shock absorber assembly. NOTICE: Keep the bolts inserted. |
|
(c) Remove the top and bottom bolts one at a time and confirm that the steering knuckle can move freely in the front shock absorber assembly.
HINT:
- Reinstall each bolt after removing it and confirming steering knuckle movement.
- If the steering knuckle does not move freely in the front shock absorber assembly, clean the contact surfaces of the front shock absorber assembly and the steering knuckle.
(d) Temporarily install the 2 nuts. (Step A)
|
(e) Fully push or pull the front axle hub in the direction of the required adjustment. (Step B) |
|
|
(f) Tighten the 2 nuts. Torque: 270 N·m {2753 kgf·cm, 199 ft·lbf} NOTICE: Keep the bolts from rotating when tightening the nuts. |

(1) If the measured value is not within the specification, calculate the required adjustment amount using the formula below. Camber adjustment amount = center of the specified range - measured value Check the combination of the installed bolts. Select appropriate bolts from the tables below to adjust the camber to the specified values. HINT: Try to adjust the camber to the center of the specified values.
The vehicle body and suspension may be damaged if the camber cannot be correctly adjusted according to the table above. NOTICE: Replace the nut with a new one when replacing the bolt. |
