FRONT WHEEL ALIGNMENT INSPECTION

Note

For vehicles equipped with VSC, if 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:


  1. Disconnect the negative battery terminal for more than 2 seconds.

  2. Reconnect the negative battery terminal.


  1. INSPECT TIRES


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

      Cold Tire Inflation Pressure
      Engine Type Tire Size Condition

      Front

      kPa (kgf/cm2, psi)

      Rear

      kPa (kgf/cm2, psi)
      1KR-FE 155/65R14 75T Driving below 160 km/h (100mph) 220 (2.2, 32) 220 (2.2, 32)
      Driving over 160 km/h (100mph) 230 (2.3, 34) 230 (2.3, 34)
      2WZ-TV Driving below 160 km/h (100mph) 240 (2.4, 35) 220 (2.2, 32)
      Driving over 160 km/h (100mph) 240 (2.4, 35) 230 (2.3, 34)
    2. A0138ZIE01

      Using a dial indicator, check the tire runout.

      Tire runout
      1.4 mm (0.055 in.) or less

  2. MEASURE VEHICLE HEIGHT

    A0136ALE01
    Vehicle height (unloaded vehicle)
    Engine Type A-B C-D
    1KR-FE 88 mm (3.46 in.) 22 mm (0.87 in.)
    2WZ-TV 89 mm (3.50 in.) 22 mm (0.87 in.)
    Measuring points
    A
    Ground clearance of front wheel center
    B
    Ground clearance of lower suspension arm front bolt center
    C
    Ground clearance of rear wheel center
    D
    Ground clearance of rear axle beam set bolt center

    Note

    Before inspecting the wheel alignment, inspect the vehicle height.

    Tech Tips

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

  3. INSPECT TOE-IN

    A0137RSE02
    Toe-in (unloaded vehicle)
    A+B C-D

    -0°06' to 0°21'

    (-0.1°to 0.35°)

    -0.9 mm to 3.1 mm

    (-0.04 in. to 0.12 in.)

    Tech Tips

    Measure C-D only when A+B can not be measured.

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

  4. ADJUST TOE-IN

    A01360ZE01

    1. Remove the rack boot set clips

    2. Loosen the tie rod end lock nuts.

    3. Turn the right and left rack ends uniformly to adjust the toe-in.

      Toe-in
      0.1 mm to 2.1 mm (0 in. to 0.08 in. )

      Tech Tips

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

    4. A0138J9E01

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

      Rack end length difference
      1.5 mm (0.059 in.) or less

    5. Torque the tie rod end lock nuts.

      Torque:
      47 N*m  { 479 kgf*cm, 35 ft.*lbf }

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

      Tech Tips

      Make sure that the boots are not twisted.

  5. INSPECT WHEEL TURNING ANGLE

    A013721E05

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

      Wheel turning angle (unloaded vehicle)
      Inside Wheel

      Outside Wheel

      (Reference)

      36°55' to 40°55'

      (36.92° to 40.92°)

      32°23'

      (32.38°)

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

  6. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

    A0136MQE04

    1. Install the camber-caster-steering axis inclination gauge at the center of the axle hub or drive shaft and position the front wheel on the alignment tester.

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

      Camber, caster and steering axis inclination (unloaded vehicle)
      Engine Type Camber Caster

      Steering Axis Inclination

      (Reference)
      1KR-FE

      -1°32' to -0°02'

      (-1.53° to -0.03°)

      2°02' to 3°32'

      (2.03° to 3.53° )

      9°33'

      (9.55°)
      2WZ-TV

      -1°32' to -0°02'

      (-1.53° to -0.03°)

      1°58' to 3°28'

      (1.97° to 3.47° )

      9°33'

      (9.55°)

      Note

      The tolerance for the difference between the left and right wheels is 30' (0.5°) or less for both the camber and caster.

      Tech Tips

      There is no camber, caster or steering axis inclination adjusting mechanism.

      If the measured values are not within the specified ranges, inspect the suspension parts and replace them if necessary.

  7. FRONT WHEELS FACING STRAIGHT AHEAD

  8. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL (w/ VSC)

    Note

    Disconnect the negative battery terminal for more than 2 seconds.

  9. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL (w/ VSC)
