FRONT WHEEL ALIGNMENT ADJUSTMENT

Note

If the wheel alignment has been adjusted, or 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:

  • Perform zero point calibration of the yaw rate and acceleration sensor.

  1. INSPECT TIRES

    1. Check the tires for wear and proper inflation pressure.

      Cold Tire Inflation Pressure
      Tire Size

      Front

      kPa (kgf/cm2, psi)

      Rear

      kPa (kgf/cm2, psi)

      P205/65R16 94S

      P215/55R17 93V

      		 240 (2.4, 35)

    2. Using a dial indicator, check the runout of the tires.

      A011XMF
      Maximum tire runout
      1.4 mm (0.0551 in.)

  2. MEASURE VEHICLE HEIGHT

    A011YUFE01

    Note

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

    • Be sure to perform measurement on a level surface.

    • If it is necessary to go under the vehicle for measurement, confirm that the parking brake is applied and the vehicle is secured with chocks.

    • Inspect while the vehicle is unloaded.

    • 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.

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

    2. Measure the vehicle height.

        Measurement points:

      • A: Ground clearance of front wheel center

      • B: Ground clearance of lower No. 2 suspension arm bushing set bolt center

      • C: Ground clearance of rear wheel center

      • D: Ground clearance of strut rod set bolt center

      Vehicle Height (Unloaded Vehicle)
      Tire Size Front A - B Rear C - D
      205/65R16 123 mm (4.84 in.) 51 mm (2.00 in.)
      215/55R17 126 mm (4.96 in.) 54 mm (2.13 in.)

  3. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

    Note

    Inspect while the vehicle is unloaded.

    1. Install a camber-caster-kingpin gauge and place the front wheels on the center of a turning radius gauge.

      *1 Turning Radius Gauge
      *2 Camber-caster-kingpin Gauge

    2. Inspect the camber, caster and steering axis inclination.

      Camber (Unloaded Vehicle)
      Camber Inclination Right-left Difference
      -0°40' +/- 45' (-0.67° +/- 0.75°) 45' (0.75°) or less
      Caster (Unloaded Vehicle)
      Caster Inclination Right-left Difference
      2°55' +/- 45' (2.92° +/- 0.75°) 45' (0.75°) or less
      Steering Axis Inclination (Unloaded Vehicle)
      Steering Axis Inclination Reference
      12°15' (12.25°)

  4. ADJUST CAMBER

    Note

    Inspect toe-in after the camber has been adjusted.

    1. Remove the front wheel.

    2. Remove the 2 nuts on the lower side of the front shock absorber.

      A011XKN

      Note

      Keep the bolts inserted.

    3. Remove the top and bottom bolts one at a time and confirm that the steering knuckle can move freely in the front shock absorber.

      Tech Tips

      • Reinstall each bolt after removing it and confirming steering knuckle movement.

      • If the steering knuckle does not move freely in the front shock absorber, clean the installation surfaces of the front shock absorber and the steering knuckle.

    4. Temporarily install the 2 nuts. (Step A)

    5. Fully push or pull the front axle hub in the direction of the required adjustment. (Step B)

      A011WEME05

    6. Tighten the nuts.

      A011XKN
      Torque:
      290 N*m  { 2957 kgf*cm, 214 ft.*lbf }

      Note

      Keep the bolts from rotating when tightening the nuts.

    7. Install the front wheel.

      Torque:
      103 N*m  { 1049 kgf*cm, 76 ft.*lbf }

    8. Check the camber.

      A011XAGE01

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

      Camber adjustment amount = center of the specified range - measured value

      Check the combination of the installed bolts. Select appropriate bolts from the tables below to adjust the camber to the specified values.

      Tech Tips

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

      To move the axle hub toward (+) in step B To move the axle hub toward (-) in step B
      Refer to table (1) (To move the axle hub toward the positive side) Refer to table (2) (To move the axle hub toward the negative side)

      The body and suspension may be damaged if the camber cannot be correctly adjusted according to the tables above.

      Note

      Replace the nut with a new one when replacing the bolt.

        *e 90105-17014 *f 90105-17015

    9. If the camber was out of adjustment in the previous step, perform the adjust camber steps mentioned above. In step (A), replace the existing bolts with the selected bolts.

      Tech Tips

      Replace one bolt at a time when replacing both bolts.

  5. INSPECT TOE-IN

    Note

    Inspect while the vehicle is unloaded.

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

    2. Release the parking brake and move the shift lever to N.

    3. Push the vehicle straight ahead approximately 5 m (16.4 ft.). (Step C)

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

      *b Dimension B
      A011YFS Front of the Vehicle

    5. Slowly push the vehicle straight ahead to cause the front wheels to rotate 180°. Use 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 C again.

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

      A011VK3E05
      Text in Illustration
      *a Dimension A
      A011YFS Front of the Vehicle
      Toe-in (Unloaded Vehicle)
      Specified Condition
      C + D: 0°00' +/- 0°10' (0.00° +/- 0.17°)
      B - A: 0 +/- 2.0 mm (0 +/- 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 rack ends.

  6. ADJUST TOE-IN

    1. Make sure that the thread length of the right and left rack ends are approximately the same.

      A011YXGE01
      Text in Illustration
      *a Thread Length
      Standard difference
      1.5 mm (0.0591 in.) or less

    2. Remove the boot clips.

    3. Loosen the tie rod end lock nuts.

      A011YET

    4. Adjust the rack ends if the difference in thread length between the right and left rack ends is not within the specified range.

      1. If the toe-in measurement is greater than the specified range (too much toe-out), extend the shorter 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-in), shorten the longer rack end so that the length difference is within the specified range.

      3. Measure the toe-in.

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

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

    7. Tighten the tie rod end lock nuts.

      Torque:
      74 N*m  { 755 kgf*cm, 55 ft.*lbf }

    8. Place the boots on the seats and install the clips.

      Tech Tips

      Make sure that the boots are not twisted.

  7. INSPECT WHEEL ANGLE

    1. Put tread center marks on the rearmost points of a turning radius gauge.

      Text in Illustration
      *a Inside
      *b Outside
      A011YFS Front of the Vehicle

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

      Note

      Inspect while the vehicle is unloaded.

      Wheel Turning Angle (Unloaded Vehicle)
      Tire Size Inside Wheel Outside Wheel
      205/65R16 37°15' +/- 2°(37.25° +/- 2°) 32°50' +/- 2°(32.83° +/- 2°)
      215/55R17 37°10' +/- 2°(37.17° +/- 2°) 32°50' +/- 2°(32.83° +/- 2°)

      • If the right and left inside wheel angles differ from the specified value, check and adjust the right and left rack end lengths.

  8. PLACE FRONT WHEELS FACING STRAIGHT AHEAD

  9. PERFORM YAW RATE AND ACCELERATION SENSOR CALIBRATION
