Front Wheel Alignment: Adjustment: Adjustment

1. Inspect the tires. Refer to INSPECTION - Step 1 .

1. Bounce the vehicle at the corners up and down to stabilize the suspension and inspect the vehicle height.
   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 required 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. Release the parking brake and move the shift lever to N.
3. Push the vehicle straight ahead approximately 5 m (16.4 ft.).*1
4. Put tread center marks on the rearmost points of the front wheels and measure the distance between the marks (dimension B).

5. Slowly push the vehicle straight ahead to cause the front wheels to rotate 180° using a front tire pressure valve as a reference point.

   HINT: 

   Do not allow the wheels to rotate more than 180°. If the wheels rotate more than 180°, perform the procedure from *1 again.

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

   TOE-IN (UNLOADED VEHICLE)
   
   

   Toe-in (Total)
   C + D: 0°06' +/- 11' (0.09° +/- 0.19°) B - A: 1.0 +/- 2.0 mm (0.04 +/- 0.08 in.)

   NOTE:

   Inspect while the vehicle is unloaded.

   HINT: 

   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.

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

   *1	Thread Length

   Standard

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

2. Remove the rack boot set clips.
3. Loosen the tie rod end lock nuts.
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. Shorten the longer rack end if the measured toe-in deviates toward the outer-side.
   2. Extend the shorter rack end if the measured toe-in deviates toward the inner-side.
5. 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.

6. Make sure that the lengths of the right and left rack ends are the same.
7. Tighten the tie rod end lock nuts.

   Torque: 56 N*m (570 kgf*cm, 41 ft.*lbf) 

   NOTE:

   Temporarily tighten the lock nut while holding the hexagonal part of the rack end so that the lock nut and the rack end do not turn together. Hold the notches on the tie rod end and tighten the lock nut.

8. Place the rack boots on the seats and install the rack boot set clips.

   HINT: 

   Make sure that the boots are not twisted.

1. Put tread center marks on the rearmost points of a wheel alignment tester.
