Rear Wheel Alignment: Adjustment

NOTE: If the wheel alignment has been adjusted, and if suspension or underbody components have been removed/installed or replaced, be sure to perform the following initialization procedure in order for the system to function normally:

Disconnect the cable from the negative battery terminal for more than 2 seconds.
Reconnect the cable to the negative battery terminal.
Perform zero point calibration of the yaw rate and acceleration sensor and test mode inspection.

HINT:

(See CALIBRATION )

INSPECT TIRES
1. Inspect the tires (See INSPECTION ).
MEASURE VEHICLE HEIGHT (See FRONT WHEEL ALIGNMENT )

INSPECT TOE-IN

Toe-in (Unloaded Vehicle)

TOE-IN REFERENCE

Item	Engine	Model	Specified Condition
Toe-in (total)	1AR-FE	2WD	C + D: 0°21' +/- 0°12' (0.35° +/- 0.2°) B - A: 4.4 +/- 2.0 mm (0.17 +/- 0.08 in.)
	2GR-FE	2WD	C + D: 0°20' +/- 0°12' (0.34° +/- 0.2°) B - A: 4.3 +/- 2.0 mm (0.17 +/- 0.08 in.)
	2GR-FE	4WD	C + D: 0°17' +/- 0°12' (0.29° +/- 0.2°) B - A: 3.6 +/- 2.0 mm (0.14 +/- 0.08 in.)

If toe-in is not within the specified range, adjust it at the rear No. 2 suspension arms.

HINT:

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

ADJUST TOE-IN (for 2WD)
1. Measure the lengths of the right and left rear No. 2 suspension arms.
  Standard difference:
  
  1.5 mm (0.06 in.) or less
  
  If the left-right difference is larger than 1.5 mm (0.06 in.), adjust it by following the procedures below.

2. Loosen the 2 lock nuts.
3. If the length difference between the left and right rear No. 2 suspension arm assemblies is not within the specified range, adjust it by following the procedures below.
  HINT:
  - Try to adjust toe-in to the center of the specified range.
  - One turn of each adjusting tube will adjust toe-in by approximately 11.1 mm (0.44 in.).

  1. If the toe-in measurement is greater than the specified range, extend the shorter rear No. 2 suspension arm assembly by rotating the adjusting tube in the direction of arrow B in the illustration.
  2. If the toe-in measurement is less than the specified range, shorten the longer rear No. 2 suspension arm assembly by rotating the adjusting tube in the direction of arrow A in the illustration.
  3. Measure the toe-in.
4. Turn the right and left adjusting tubes by an equal amount to adjust toe-in.
5. Tighten the 2 lock nuts.
  Torque: 56 N*m (571 kgf*cm, 41 ft.*lbf)
ADJUST TOE-IN (for 4WD)
1. Measure the distance between each wheel disc and the center of the toe-adjusting cam, and then confirm that left and right distances are the same.
  Difference in the length of rear No. 2 suspension arms:
  
  1.0 mm (0.04 in.) or less
  
  If the left-right difference is larger than 1.0 mm (0.04 in.), adjust it by following the procedures below.
2. Loosen the toe-adjust cam set nuts.

3. Turn the adjust cams by an equal amount to adjust toe-in.
  HINT:
  - Try to adjust toe-in to the center of the specified range.
  - The toe-in will change by the following amount corresponding to each graduation of the cam. Approx. 3.3 mm (0.13 in.)
4. Tighten the toe-adjust cam set nuts.
  Torque: 100 N*m (1019 kgf*cm, 74 ft.*lbf)

INSPECT CAMBER

Camber (Unloaded Vehicle)

CAMBER REFERENCE

Engine	Model	Camber Inclination	Right-left difference
1AR-FE	2WD	-1°02' +/- 45' (-1.03° +/- 0.75°)	45' (0.75°) or less
2GR-FE	2WD	-1°00' +/- 45' (- 1.00° +/- 0.75°)
2GR-FE	4WD	-0°36' +/- 45' (- 0.60° +/- 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.

PLACE FRONT WHEELS FACING STRAIGHT AHEAD
DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
NOTE: Disconnect the cable from the negative battery terminal for more than 2 seconds.
CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
NOTE: When disconnecting the cable, some systems need to be initialized after the cable is reconnected (See INITIALIZATION ).
PERFORM YAW RATE SENSOR ZERO POINT CALIBRATION
HINT:

Perform yaw rate sensor zero point calibration (See CALIBRATION ).
CHECK STEERING ANGLE SENSOR ZERO POINT CALIBRATION
HINT:

Check steering angle sensor zero point calibration (See DTC C1290 STEERING ANGLE SENSOR ZERO POINT MALFUNCTION ).
