1. Jack up the rear wheels, and place an axle stand at the
designated part of the side sill.
2. Jack up the front wheels and set a pick-up stand and
balancing machine in place.
Caution
1.Set so that the front and rear of the vehicle are at
the same height.
2. Release the parking brake.
3. Rotate each wheel manually and check to be sure
that there is no dragging.
3. Use the engine to drive the tires, and then make the
measurement.Caution
1.If an error is indicated in the state of engine drive,
motor drive can be used concurrently.
2. Do not operate the clutch
suddenly, or increase or
reduce speed suddenly during the work.
REAR WHEEL MEASUREMENTS
1. Jack up the front wheels, and place an axle stand at the
designated part of the side sill.
2. Jack up the rear wheels, and then, after setting a pick-up
stand and balancing machine in place, follow the same
procedure as for front wheel measurements.

In addition to a malfunction of the differential carrier components, abnormal noise can also be caused by the universal
joint of the propeller shaft, the axle shafts, the wheel bearings, etc. Before disassembling any parts, take all
possibilities into consideration and confirm the source of the noise.

Noise from the engine, muffler vibration, transaxle, propeller shaft, wheel bearings, tires, body, etc., is easily mistaken
as being caused by malfunctions in the differential carrier components. Be extremely careful and attentive whenperforming the driving test, etc.
Test methods to confirm the source of the abnormal noise include:coasting acceleration, constant speed driving,
raising the rear wheels on a jack, etc. Use the method most appropriate to the circumstances.
