Front Wheel Alignment (2WD)

WARNING: This page does not describe the selected car, but rather 16 other vehicles, including the 2002 Toyota Tundra, 2002 Toyota Tacoma, 2002 Toyota Sienna, 2002 Toyota Sequoia, and 2002 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

Measure vehicle height (see Wheel Alignment Specifications (Tacoma) table) .
1. Measuring points:
  1. Ground clearance of spindle center. See Fig 1.

  2. Ground clearance of lower suspension arm bolt center.
  3. Ground clearance of rear axle shaft center.
  4. Ground clearance of leaf spring front hanger pin bolt center.
  NOTE: Before inspecting the wheel alignment, adjust the vehicle height to the specified value.
  
  If the vehicle height is not the specified value, try to adjust it by pushing down on or lifting the body.
Install camber/caster/kingpin gauge or position vehicle on wheel alignment tester .
1. Follow the specific instructions of the equipment manufacturer.
Inspect camber, caster and steering axis inclination (see Wheel Alignment Specifications (Tacoma) table .
1. If the steering axis inclination is not within the specified value, after the camber and caster have been correctly adjusted, recheck the steering knuckle and front wheel for bearing or looseness.
Adjust camber and caster .
1. Loosen the upper suspension arm set bolts.
2. Adjust the camber and caster by adding or removing shims. See Fig 4.

  NOTE: Try to adjust the camber and caster to the center of the specified values.
3. How to read adjustment chart.
  1. Find the wheel alignment standard value applicable for the particular model. See Wheel Alignment Specifications (Tacoma) table.
  2. Mark the selected standard value on the adjustment chart.
    Example :
    1. Camber: 0°00
    2. Caster: 0°30'(0.5°)
  3. Mark the alignment value measured when the vehicle was non-loaded on the adjustment chart.
    Example :
    1. Camber: 0°00
    2. Caster: 1°48'(1.8°)
  4. Read the distance from the measured value to the standard value, and adjust the front and/or rear shim thickness accordingly.
    Example :
    1. Front shim thickness: -1.2 mm (-0.047 in.)
    2. Rear shim thickness: +1.2 mm (0.047 in.)
4. Torque the upper suspension arm set bolts.
  Torque: 130 N.m (1,300 kgf.cm. 94 ft.lbf)
  
  NOTE: If the steering axis inclination is not as specified value after the camber and caster have been correctly adjusted, recheck the steering knuckle and front wheel for distortion or looseness.
  
  NOTE: Adjust the shim thickness to 7 mm (4-11 mm), and adjust the difference between the front and rear of the upper suspension arm shaft to within 4 mm.
Inspect toe-in (see Wheel Alignment Specifications (Tacoma) table) .

If the toe-in is not within the specified value, adjust the rack ends.
Adjust toe-in .
1. Remove the 2 clips.
2. Loosen the tie rod end lock nuts.
3. Turn the right and left rack ends by an equal amount to adjust the toe-in.
  NOTE: Try to adjust the toe-in to the center of the specified value.

  Rack end length difference: 1.5 mm (0.059 in.) or less
5. Tighten the tie rod end lock nuts.
  1. Torque: 54 N.m (550 kgf.cm, 40 ft.lbf)
6. Place the boots on the seats and install the clips.
  NOTE: Make sure that the boots are not twisted.
Inspect wheel angle .
1. Turn the steering wheel fully and measure the turning angle.

  If the right and left inside wheel angles differ from the specified value, check the right and left rack end lengths.
  
  NOTE: If the rack ends lengths are not equal, the wheel turning angle cannot be adjusted properly.
  
  Reinspect the toe-in after adjusting the rack ends lengths.
