2. MEASURE VEHICLE HEIGHT

   

   Note

   
   

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

   • Be sure to perform the measurement on a level surface.

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

   
   

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

   2. Measure the vehicle height.

      Measuring points
      A
      Ground clearance of center of front lower No. 1 suspension arm bushing set bolt
      B
      Ground clearance of center of rear No. 2 suspension arm bushing set bolt
      C
      Ground clearance of center of front wheel
      D
      Ground clearance of center of rear wheel

      Note

      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.

      Standard Vehicle Height (Unloaded Vehicle)
      Tire Size Front C - A Rear D - B 225/65R17 111 mm (4.37 in.) 73 mm (2.87 in.) 225/60R18 116 mm (4.57 in.) 78 mm (3.07 in.) 235/55R18 111 mm (4.37 in.) 73 mm (2.87 in.)

3. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION

   
   
   1. 

      *a	Alignment Tester
      *b	Gauge

      Install a camber-caster-kingpin gauge or place the front wheels on the center of a wheel alignment tester.

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

      Standard Camber Inclination (Unloaded Vehicle)
      Camber Inclination Right-left Difference -0°15' +/-45' (-0.25° +/-0.75°) 30' (0.50°) or less

      Standard Caster Inclination (Unloaded Vehicle)
      Tire Size Caster Inclination Right-left Difference 225/65R17 6°00' +/-45' (6.00° +/-0.75°) 30' (0.50°) or less 225/60R18 6°05' +/-45' (6.08° +/-0.75°) 30' (0.50°) or less 235/55R18 6°00' +/-45' (6.00° +/-0.75°) 30' (0.50°) or less

      Standard Steering Axis Inclination (Unloaded Vehicle)

4. ADJUST CAMBER

   Note

   Inspect toe-in after the camber has been adjusted.

   
   

   1. Remove the front wheel.

      Click here

   2. 

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

      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.

      Note

      Do not apply lubricants to the steering knuckle and shock absorber contact surfaces.

      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. 

      *a	Negative Side
      *b	Positive Side

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

   6. 

      Tighten the nuts.

      Torque:

      240 N*m  { 2447 kgf*cm, 177 ft.*lbf }

      Note

      Prevent the bolts from rotating when tightening the nuts.

   7. Install the front wheel.

   8. Check the camber.

      Standard Camber Inclination (Unloaded Vehicle)
      Camber Inclination Right-left Difference -0°15' +/-45' (-0.25° +/-0.75°) 30' (0.50°) or less

      Tech Tips

      Perform adjustments so that the value is as close as possible to the median of the specified range.

   9. 

      Check the camber.

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

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

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

      Tech Tips

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

      Move Axle toward (+) in Step (B)	Move Axle toward (-) in Step (B)
      Refer to table (1) (When moving the axle toward the positive side)	Refer to table (2) (When moving the axle toward the negative side)

      Note

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

      
      

      1. Table (1) (To move the axle hub toward the positive side)

         

         *A	Table (1) (To move the axle hub toward the positive side)	*B	Selected Bolt Combination
         *a	Installed Bolt	*b	Adjusting Value
         *c	Standard Bolt	*d	90105-17009
         *e	90105-17010	*f	90105-17011

      2. Table (2) (To move the axle hub toward the negative side)

         

         *A	Table (2) (To move the axle hub toward the negative side)	*B	Selected Bolt Combination
         *a	Installed Bolt	*b	Adjusting Value
         *c	Standard Bolt	*d	90105-17009
         *e	90105-17010	*f	90105-17011

   10. 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

   
   

   1. 

      Front of the Vehicle

      Bounce the vehicle up and down at the corners to stabilize the suspension and inspect toe-in.

      Toe-in (Unloaded Vehicle)
      A + B C - D A + B: 0°10' +/-10' (0.16°+/-0.16°) C - D: 2.0 +/-2.0 mm (0.08 +/-0.08 in.)

      Tech Tips

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

6. ADJUST TOE-IN

   
   
   1. 

      *a	Difference

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

      Standard difference
      1.5 mm (0.06 in.) or less

   2. Remove the boot clips.

   3. 

      *a	Loosen
      *b	Turn

      Loosen the tie rod end lock nuts.

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

      Toe-in (Unloaded Vehicle)
      A + B C - D A + B: 0°10' +/-10' (0.16°+/-0.16°) C - D: 2.0 +/-2.0 mm (0.08 +/-0.08 in.)

      Tech Tips

      Perform adjustments so that the value is as close as possible to the median of the specified range.

   5. Tighten the tie rod end lock nuts.

      Torque:

      88 N*m  { 897 kgf*cm, 65 ft.*lbf }

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

      Note

      Make sure that the claws of the clip are facing in the direction that the vehicle travels.

      Tech Tips

      Make sure that the boots are not twisted.

7. INSPECT WHEEL ANGLE

   

   *a	Inside
   *b	Outside
   	Front of the Vehicle

   
   

   1. Turn the steering wheel to the left and right full lock positions and measure the turning angle.

      Standard Wheel Turning Angle (Unloaded Vehicle)
      Tire Size Inside Wheel Outside Wheel (Reference) 225/65R17 35°37' +/-2° (35.62° +/-2°) 30°14' (30.23°) 225/60R18 35°37' +/-2° (35.62° +/-2°) 30°14' (30.23°) 235/55R18 35°37' +/-2° (35.62° +/-2°) 30°14' (30.23°)

      
      

      • If the angles are not as specified, check and adjust the right and left rack end lengths.
