PROCEDURE

1. INSPECT TIRES

Click here 2019 - 2020 MY Avalon Avalon HV [04/2018 - 08/2020]; TIRE / WHEEL: TIRE AND WHEEL SYSTEM: INSPECTION+

2. MEASURE VEHICLE HEIGHT

NOTICE:

  • 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 performing a wheel alignment and does not indicate the height of an actual vehicle.

(a) Bounce the vehicle up and down at the corners to stabilize the suspension.

(b) Measure the vehicle height.

Measurement Points:

  • A: Ground clearance of front wheel center
  • B: Ground clearance of center of bolt head of front lower No. 2 suspension arm bushing (rear bolt of front lower No. 1 suspension arm sub-assembly).
  • C: Ground clearance of rear wheel center
  • D: Ground clearance of center of bolt head of rear No. 2 suspension arm assembly and rear suspension member sub-assembly.

(1) 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.

HINT:

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

5. INSPECT TOE-IN

NOTICE:

Inspect while the vehicle is unloaded.

(a) Bounce the vehicle up and down at the corners to stabilize the suspension.

(b) Release the parking brake and move the shift lever to N.

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

Front of the Vehicle

(e) Slowly push the vehicle straight ahead to cause the front wheels to rotate 180°. Use the front tire 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 step C again.

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

Thread Length

(b) Separate the steering rack boot clips from the steering rack boot.

(c) Loosen the tie rod assembly lock nuts.

(d) Adjust the steering rack ends if the difference in thread length between the right and left steering 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 difference in length 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 difference in length is within the specified range.

(3) Measure the toe-in.

(e) Turn the right and left steering rack ends by an equal amount to adjust the toe-in.

HINT:

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