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 bolt head of rear No. 2 suspension arm assembly and rear suspension member sub-assembly. Vehicle Height (Unloaded Vehicle): Model Tire Size Front A - B Rear C - D GSX50L-AEZGBA 215/55R17 148 mm (5.83 in.) 45 mm (1.77 in.) GSX50L-AEZQBA 235/40R19 150 mm (5.91 in.) 52 mm (2.05 in.) GSX50L-AEZPBA 235/45R18 153 mm (6.02 in.) 51 mm (2.01 in.) 235/40R19 153 mm (6.02 in.) 50 mm (1.97 in.) GSX50L-AEZSBA 235/40R19 151 mm (5.94 in.) 54 mm (2.13 in.) AXXH50L-AEXGBA 215/55R17 235/45R18 147 mm (5.79 in.) 50 mm (1.97 in.) AXXH50L-AEXQBA 235/45R18 154 mm (6.06 in.) 52 mm (2.05 in.) 235/40R19 153 mm (6.02 in.) 52 mm (2.05 in.) AXXH50L-AEXPBA 235/45R18 152 mm (5.98 in.) 51 mm (2.01 in.)

3. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

NOTICE:

Inspect while the vehicle is unloaded.

(a) Install a camber-caster-kingpin gauge and place the front wheels on the center of a turning radius gauge.

*a Turning Radius Gauge *b Camber-caster-kingpin Gauge

(b) Inspect the camber, caster and steering axis inclination.

Steering Axis Inclination (Unloaded Vehicle):

4. ADJUST CAMBER

NOTICE:

Inspect toe-in after the camber has been adjusted.

(a) Remove the front wheel.

(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.

(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: 290 N·m {2957 kgf·cm, 214 ft·lbf} NOTICE: Keep the bolts from rotating when tightening the nuts.

(g) Install the front wheel.

(h) Bounce the vehicle up and down at the corners to stabilize the suspension.

(i) Check the camber.

Camber (Unloaded Vehicle):

(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. To move the axle hub toward (+) in step B To move the axle hub toward (-) in step B Refer to table (1) (To move the axle hub toward the positive side) Refer to table (2) (To move the axle hub toward the negative side) 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.

(2) Table (1) (To move the axle hub toward the positive side)

(3) Table (2) (To move the axle hub toward the negative side)

(j) If the camber was out of adjustment in the previous step, perform the adjust camber steps mentioned above. In step A, replace the existing bolts with the selected bolts.

HINT:

Replace one bolt at a time when replacing both bolts.

5. INSPECT TOE-IN

NOTICE:

Inspect while the vehicle is unloaded.

(a) Bounce the vehicle up and down at the corners to stabilize the suspension.

(b) Release the parking brake and move the shift lever to N.

(c) Push the vehicle straight ahead approximately 5 m (16.4 ft.). (Step C)

(d) Put tread center marks on the rearmost points of the front wheels and measure the distance between the marks (dimension B).

*a	Tread Center Mark
*b	Dimension B
	Front of the Vehicle

(e) Slowly push the vehicle straight ahead to cause the front wheels to rotate 180°. Use the front tire valve as a reference point.

HINT:

Do not allow the wheels to rotate more than 180°. If the wheels rotate more than 180°, perform the procedure from step C again.

(f) Measure the distance between the tread center marks on the front of the wheels (dimension A).

*a	Dimension A
	Front of the Vehicle

Toe-in (Unloaded Vehicle):

HINT:

Measure "B - A" only when "C + D" cannot be measured.

If the toe-in is not within the specified range, adjust it at the steering rack ends.

6. ADJUST TOE-IN

(a) Make sure that the thread length of the right and left steering rack ends are approximately the same. Standard Difference: 1.5 mm (0.0591 in.) or less

*a Thread Length

(b) Separate the steering rack boot clips from the steering rack boot.

(c) Loosen the tie rod assembly lock nuts.

(d) Adjust the steering rack ends if the difference in thread length between the right and left steering rack ends is not within the specified range.

(1) If the toe-in measurement is greater than the specified range (too much toe-out), extend the shorter rack end so that the difference in length is within the specified range.

(2) If the toe-in measurement is less than the specified range (too much toe-in), shorten the longer rack end so that the difference in length is within the specified range.

(3) Measure the toe-in.

(e) Turn the right and left steering rack ends by an equal amount to adjust the toe-in.

HINT:

Perform adjustments so that the value is as close as possible to the median of the specified range.

Front of the Vehicle

Toe-in (Unloaded Vehicle):

(f) Make sure that the thread length of the right and left steering rack ends are the same.

(g) Tighten the tie rod assembly lock nuts.

Torque:

88 N·m {897 kgf·cm, 65 ft·lbf}

(h) Place the steering rack boots on the seats and install the steering rack boot clips.

7. INSPECT WHEEL ANGLE

(a) Put tread center marks on the rearmost points of a turning radius gauge.

*a	Inside
*b	Outside
	Front of the Vehicle

(b) Turn the steering wheel fully to the left and right and measure the turning angle.

NOTICE:

Inspect while the vehicle is unloaded.
