Front Wheel Alignment Adjustment

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

Vehicle height:

3GR-FSE 3GR-FE

Front (A-B)	Rear (C)
111 mm (4.37 in.)	211 mm (8.31 in.)

3UZ-FE

Front (A-B)	Rear (C)
113 mm (4.45 in.)	208 mm (8.19 in.)

Measuring points:

A:

Ground clearance of front wheel center

B:

Ground clearance of front center position of front suspension lower arm assembly front bush installation bolt head

C:

Ground clearance of rear center position of rear suspension No.2 arm bush installation bolt screw thread

NOTICE:

Before inspecting the wheel alignment, adjust the vehicle height to the specified value.

HINT:

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

Toe-in:

Toe-in (total)

A - B: 1+- 2 mm (0.04 +- 0.08 in.)

HINT:

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

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

Standard:

Difference in thread lengths is 1.5 mm (0.059 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 toe-in.

HINT:

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

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

Tighten the tie rod end lock nuts.

Torque:

56 N*m{571 kgf*cm, 41 ft.*lbf}

NOTICE:

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 boots on the seats and install the clips.

NOTICE:

Perform VGRS calibration after adjusting toe-in.

HINT:

Make sure that the boots are not twisted.

Turn the steering wheel fully left and right and measure the turning angle.

Wheel turning angle:

3GR-FSE 3GR-FE

Inside wheel	Outside wheel: Reference
41°49' (41.82°) +- 2°	36°11' (36.18°)

3UZ-FE

Inside wheel	Outside wheel: Reference
41°48' (41.80°) +- 2°	36°08' (36.13°)

Remove the center ornament.

Put the front wheel on the center of the alignment tester.

Install the camber-caster-steering axis inclination gauge and attachment at the center of the axle hub or drive shaft.

Inspect the camber, caster and steering axis inclination.

Camber, caster and steering axis inclination:

3GR-FSE 3GR-FE

Camber	-0°23' +- 45' (-0.38° +- 0.75°)
Right-left error	30' (0.5°) or less
Caster	7°23' +- 45' (7.38° +- 0.75°)
Right-left error	30' (0.5°) or less
Steering axis inclination	9°23' +- 45' (9.38° +- 0.75°)
Right-left error	30' (0.5°) or less

3UZ-FE

Camber	-0°26' +- 45' (-0.43° +- 0.75°)
Right-left error	30' (0.5°) or less
Caster	7°26' +- 45' (7.43° +- 0.75°)
Right-left error	30' (0.5°) or less
Steering axis inclination	9°26' +- 45' (9.43° +- 0.75°)
Right-left error	30' (0.5°) or less

NOTICE:

1. Inspect while the vehicle is empty.
   
2. The maximum tolerance of right and left difference for the camber and caster is 30' or less.
   

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

Install the center ornament.
If the measured value is not within the specified range, inspect the suspension parts for damage and wear. Replace parts as necessary because camber, caster and steering axis inclination cannot be properly adjusted with any damage or worn parts.

Inspect the front suspension member.

1. Measure the dimension between the center of the installation bolts of the front suspension lower arm assembly.
   

   Standard:

   692.5 to 699.5 mm (27.26 to 27.54 in.)
   

   If the result is not within the specification, replace the front suspension member.
   

Inspect the front suspension lower arm assembly.

1. Remove the front suspension lower arm assembly (Click here).
   

2. Measure the dimension between the center of the front suspension lower arm assembly bush and position A.
   

   Standard:

   362 mm (14.25 in.)
   

   HINT:

   If the dimension of the front suspension lower arm assembly changes 2 mm (0.079 in.), the camber will change approximately 15' (0.25°).

Inspect the front suspension upper arm assembly.

1. Remove the front suspension upper arm assembly (Click here).
   

2. Measure the dimension between the center of the front suspension upper arm assembly bush and the ball joint stud.
   

   Standard:

   A:

   250 mm (9.84 in.)
   

   B:

   231 mm (9.09 in.)
   

   HINT:

   If the dimension of the front suspension upper arm assembly changes 2 mm (0.079 in.), the camber will change approximately 15' (0.25°).
