Note

Before inspecting the wheel alignment, check the vehicle height.
The standard value shown here is a value that is used for adjusting the wheel alignment and does not indicate the height of an actual vehicle.

Tech Tips

Bounce the vehicle up and down at the corners to stabilize the suspension before inspecting the vehicle height.

INSPECT WHEEL TURNING ANGLE

Text in Illustration
*a	Inside
*b	Outside
	Front of the Vehicle

Fully turn the steering wheel left and right, and measure the wheel turning angle.

Wheel Turning Angle (Unloaded Vehicle)
Engine	Tire Size	Inside Wheel	Outside Wheel (Reference)
1NR-FE 1ND-TV	185/65R 15 185/60R 16	34°55'	31°14'
1NR-FE	185/60R 15	35°11'	31°35'
1NZ-FE	175/60R 16	39°57'	34°35'

If the right and left inside wheel angles are not within the specified range, check the right and left rack end lengths.

INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

Text in Illustration
*1	Alignment tester
*2	Camber-caster-steering axis inclination gauge

Put the front wheel on the center of the alignment tester.
Remove the wheel cap.
Set the camber-caster-steering axis inclination gauge at the center of the axle hub or drive shaft.

Inspect the camber, caster and steering axis inclination.

Camber Inclination (Unloaded Vehicle)
Engine	Tire Size	Camber
1NR-FE 1ND-TV	185/65R 15 185/60R 16	-0°15' +/- 45'
1NR-FE	185/60R 15	-0°04' +/- 45'
1NZ-FE	175/60R 16	-0°14' +/- 45'

Caster Inclination (Unloaded Vehicle)
Engine	Tire Size	Caster
1NR-FE 1ND-TV	185/65R 15 185/60R 16	4°47' +/- 45'
1NR-FE	185/60R 15	4°30' +/- 45'
1NZ-FE	175/60R 16	5°02' +/- 45'

Steering Axis Inclination (Unloaded Vehicle)
Engine	Tire Size	Steering Axis Inclination (Reference)
1NR-FE 1ND-TV	185/65R 15 185/60R 16	11°29'
1NR-FE	185/60R 15	11°05'
1NZ-FE	175/60R 16	11°29'

Note

Perform the inspection while the vehicle is empty (without a spare tire or tools on board).
The tolerance for the difference between the left and right wheels is 30' (0.5°) or less for both the camber and caster.

Remove the camber-caster-steering axis inclination gauge and attachment.
Install the wheel cap.

If the caster and steering axis inclination are not within the specified values after the camber has been correctly adjusted, recheck the suspension parts for damage and wear.

ADJUST CAMBER

Note

Inspect the toe-in after the camber has been adjusted.

Remove the front wheel.
Remove the bolt and separate the speed sensor and flexible hose.
Remove the 2 nuts from the lower side of the shock absorber.

Tech Tips

Keep the bolt from rotating while loosening and removing the nuts.
Clean the installation surfaces of the shock absorber and steering knuckle.
Provisionally install the 2 nuts (Step A).
Fully push or pull the axle hub in the direction of the required adjustment (Step B).
Tighten the 2 nuts.

Torque:

164 N*m { 1672 kgf*cm, 121 ft.*lbf }

Tech Tips

Keep the bolt from rotating while loosening and removing the nuts.
Install the flexible hose and speed sensor with the bolt.

Torque:

29 N*m { 300 kgf*cm, 22 ft.*lbf }

Note

Install the flexible hose and speed sensor without twisting them.
Install the front wheel.

Torque:

103 N*m { 1050 kgf*cm, 76 ft.*lbf }

Check the camber.

If the measured value is not within the specifications, calculate the required adjustment amount using the formula below.

(Camber adjustment amount) = Center of specified range - Measured value

Check the combination of installed bolts. Select appropriate bolts from the table below to adjust the camber to within the specified range.

Tech Tips

Try to adjust the camber to the center of the specified range.

Move axle toward (+) in step (B)	Refer to table (1) (Move axle toward positive side)
Move axle toward (-) in step (B)	Refer to table (2) (Move axle toward negative side)

Table (1) (Move the axle toward the positive side)
Table (2) (Move the axle toward the negative side).

The body and suspension may be damaged if the camber is not correctly adjusted in accordance with the above table.

Note

Replace the nut with a new one when replacing the bolt.
Repeat the steps mentioned above. At step (A), replace 1 or 2 selected bolts.

Tech Tips

Replace one bolt at a time when replacing 2 bolts.

INSPECT TOE-IN

Bounce the vehicle up and down at the corners to stabilize the suspension.
Release the parking brake and move the shift lever to the neutral position.
Push the vehicle straight ahead approximately 5 m (16.4 ft.). (Step A)

*a Tread Center Mark

Put tread center marks on the rearmost points of the front wheels and measure the distance between the marks (Dimension B).
Slowly push the vehicle straight ahead to cause the front wheels to rotate 180° using the front 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	Tread Center Mark

Measure the distance between the tread center marks on the front side of the wheels (Dimension A).

Toe-in
Engine	Specified Condition
1NR-FE 1ND-TV	B-A: 1.5 +/- 2.0 mm (0.0591 +/- 0.08 in.)
1NZ-FE	B-A: 1.4 +/- 2.0 mm (0.0551 +/- 0.08 in.)

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

ADJUST TOE-IN

Measure the thread lengths of the right and left rack ends.

Standard

Difference in thread length of 1.5 mm (0.0591 in.) or less
Remove the rack boot set clips.
Loosen the tie rod end lock nuts.
Adjust the rack ends if the difference in thread length between the right and left rack ends is not within the specified range.
1. Extend the shorter rack end if the measured toe-in deviates toward the outer-side.
2. Shorten the longer rack end if the measured toe-in deviates toward the inner-side.
Turn the right and left rack ends by an equal amount to adjust the toe-in.

Tech Tips

Try to adjust the toe-in to the center of the specified range.

Standard
Difference in thread length of 1.5 mm (0.0591 in.) or less

Make sure that the lengths of the right and left rack ends are the same.

Toe-in
Engine	Specified Condition
1NR-FE 1ND-TV	B-A: 1.5 +/- 2.0 mm (0.0591 +/- 0.08 in.)
1NZ-FE	B-A: 1.4 +/- 2.0 mm (0.0551 +/- 0.08 in.)

Tighten the tie rod end lock nuts to the specified torque.

Torque:

75 N*m { 760 kgf*cm, 55 ft.*lbf }

Note

Provisionally 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 flat of the tie rod end and tighten the lock nut.
Place the boots on the seats.
