INSPECT CAMBER

Note

Inspect while the vehicle is unloaded.

*a Camber-caster-kingpin Gauge

Install a camber-caster-kingpin gauge.

Inspect the camber.

Camber (Unloaded Vehicle)

Camber Inclination	Right-left Difference
-1°20' +/- 0°45' (-1.33° +/- 0.75°)	0°45' (0.75°) or less

Tech Tips

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.

INSPECT TOE-IN

Note

Inspect while the vehicle is unloaded.

Bounce the vehicle up and down at the corners to stabilize the suspension.
Release the parking brake and move the shift lever to N.
Push the vehicle straight ahead approximately 5.0 m (16.4 ft.). (Step A)

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

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

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

Tech Tips

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

*a	Dimension A
	Front of the Vehicle

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

w/ Dynamic Rear Steering	Tire Size: 245/45RF20		C + D: 0°14' +/- 0°09' (0.23° +/- 0.15°) B - A: 3.0 +/- 2.0 mm (0.1181 +/- 0.0787 in.)
	Tire Size: 275/35RF21	for Korea	C + D: 0°00' +/- 0°09' (0.00° +/- 0.15°) B - A: 0.0 +/- 2.0 mm (0.0000 +/- 0.0787 in.)
	Tire Size: 275/35RF21	except Korea	C + D: 0°14' +/- 0°09' (0.23° +/- 0.15°) B - A: 3.0 +/- 2.0 mm (0.1181 +/- 0.0787 in.)

Tech Tips

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

If the toe-in is not within the specified range, adjust it at the toe control link sub-assembly.

ADJUST TOE-IN (w/o Dynamic Rear Steering)

Loosen the nut of the toe control link sub-assembly (on the rear suspension member sub-assembly side).

Note

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

Rotate the toe adjust cam sub-assembly to adjust the toe-in.

Toe-in (Unloaded Vehicle)

Specified Condition
C + D: 0°14' +/- 0°09' (0.23° +/- 0.15°)
B - A: 3.0 +/- 2.0 mm (0.1181 +/- 0.0787 in.)

Tech Tips

Perform adjustments so that the value is as close as possible to the median of the specified range.
Rotating the toe adjust cam sub-assembly by one notch changes the toe by approximately 4.6 mm (0.181 in.).

Tighten the nut of the toe control link sub-assembly (on the rear suspension member sub-assembly side).

Torque:

78 N*m { 795 kgf*cm, 58 ft.*lbf }

Note

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

ADJUST TOE-IN (w/ Dynamic Rear Steering)

Note

If any underbody rear suspension parts are removed and installed, replaced or adjusted, the steering wheel may become off center.

Therefore, perform neutral point memorization and motor rotation angle sensor calibration.

*1 Steering Rack Boot Clip

*2 Lock Nut

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
Remove the steering rack boot clips.
Loosen the tie rod assembly lock nuts.
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-in), shorten the longer steering rack end so that the length difference is within the specified range.
2. If the toe-in measurement is less than the specified range (too much toe-out), lengthen the shorter steering rack end so that the length difference is within the specified range.
3. Measure the toe-in.

Standard Difference
1.5 mm (0.0591 in.) or less

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

Note

Temporarily tighten the lock nut while holding the hexagonal part of the steering rack end so that the lock nut and the steering rack end do not turn together.

Hold the width across flat of the tie rod end and tighten the lock nut.
Place the steering rack boots on the seats and install the steering rack boot clips.
Tech Tips
- Make sure that the steering rack boots are not twisted.
- Make sure that the steering rack boot clips are facing towards the front of the vehicle.
Perform neutral position memorization and motor rotation angle sensor calibration for the dynamic rear steering system.
