3. INSPECT CAMBER

NOTICE:

Inspect while the vehicle is unloaded.

(a) Install a camber-caster-kingpin gauge.

*a Camber-caster-kingpin Gauge

(b) Inspect the camber.

Camber (Unloaded Vehicle):

Engine	DRIVE TYPE	Camber Inclination	Right-left Difference
M20A-FXS	2WD	-1°12' +/- 0°45' (-1.20° +/- 0.75°)	0°45' (0.75°) or less
	AWD	-1°14' +/- 0°45' (-1.23° +/- 0.75°)
2ZR-FXE	2WD	-1°04' +/- 0°45' (-1.07° +/- 0.75°)

HINT:

Camber is not adjustable. If the measurement is not within the specified range, inspect the suspension parts for damage and/or wear, and replace them if necessary.

4. 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 A)

(d) Put tread center marks on the rearmost points of the rear 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 rear wheels to rotate 180°. Use the rear 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 A again.

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

Toe-in (Unloaded Vehicle):

Engine	DRIVE TYPE	Tire Size	Specified Condition
M20A-FXS	2WD	195/60R17	C + D: 0°16' +/- 0°10' (0.26° +/- 0.17°)
			B - A: 3.0 +/- 2.0 mm (0.118 +/- 0.0787 in.)
		195/50R19	C + D: 0°16' +/- 0°10' (0.26° +/- 0.17°)
			B - A: 3.1 +/- 2.0 mm (0.122 +/- 0.0787 in.)
	AWD	195/60R17	C + D: 0°16' +/- 0°10' (0.27° +/- 0.17°)
			B - A: 3.1 +/- 2.0 mm (0.122 +/- 0.0787 in.)
		195/50R19	C + D: 0°16' +/- 0°10' (0.27° +/- 0.17°)
			B - A: 3.2 +/- 2.0 mm (0.126 +/- 0.0787 in.)
2ZR-FXE	2WD	195/60R17	C + D: 0°16' +/- 0°10' (0.27° +/- 0.17°)
			B - A: 3.1 +/- 2.0 mm (0.122 +/- 0.0787 in.)

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 rear suspension toe adjust cam sub-assembly.

5. ADJUST TOE-IN

(a) Loosen the nut of the rear No. 2 suspension arm assembly (on the rear suspension member sub-assembly side).

NOTICE:

Hold the rear suspension toe adjust cam sub-assembly while rotating the nut.

*A

for 2WD

*A

for AWD

(b) Rotate the rear suspension toe adjust cam sub-assembly to adjust the toe-in.

Toe-in (Unloaded Vehicle):

Engine	DRIVE TYPE	Tire Size	Specified Condition
M20A-FXS	2WD	195/60R17	C + D: 0°16' +/- 0°10' (0.26° +/- 0.17°)
			B - A: 3.0 +/- 2.0 mm (0.118 +/- 0.0787 in.)
		195/50R19	C + D: 0°16' +/- 0°10' (0.26° +/- 0.17°)
			B - A: 3.1 +/- 2.0 mm (0.122 +/- 0.0787 in.)
	AWD	195/60R17	C + D: 0°16' +/- 0°10' (0.27° +/- 0.17°)
			B - A: 3.1 +/- 2.0 mm (0.122 +/- 0.0787 in.)
		195/50R19	C + D: 0°16' +/- 0°10' (0.27° +/- 0.17°)
			B - A: 3.2 +/- 2.0 mm (0.126 +/- 0.0787 in.)
2ZR-FXE	2WD	195/60R17	C + D: 0°16' +/- 0°10' (0.27° +/- 0.17°)
			B - A: 3.1 +/- 2.0 mm (0.122 +/- 0.0787 in.)

HINT:

• Rotating the rear suspension toe adjust cam sub-assembly by one notch changes the toe by approximately 2.6 mm (0.102 in.).
• Perform adjustments so that the value is as close as possible to the median of the specified range.

(c) Tighten the nut of the rear No. 2 suspension arm assembly (on the rear suspension member sub-assembly side).

Torque:

100 N·m {1020 kgf·cm, 74 ft·lbf}

NOTICE:

Hold the rear suspension toe adjust cam sub-assembly while rotating the nut.
