ON-VEHICLE SERVICE

FRONT AXLE TOTAL BACKLASH CHECK

M1261001300076

1. If the vehicle vibrates and produces a booming sound due to

an imbalance in the drive system, measure the front axle
total backlash by the following procedure to see if the
differential carrier assembly requires removal.

(1) Park the vehicle on a flat, level surface.
(2) Move the transmission control lever to the neutral

position. Apply the parking brake. Raise the vehicle on a
jack.

(3) Turn the companion flange clockwise as far as it will go.

Make the mating mark on the dust cover of the
companion flange and on the differential carrier.

(4) Turn the companion flange counterclockwise as far as it

will go, and measure the amount of distance the mating
marks moved.

Limit: 11 mm (0.4 inch)

2. If the backlash exceeds the limit, remove the differential

carrier assembly and final drive gear. Then check the
differential gear meshing condition and the looseness of the
driveshaft or inner shaft splines.

FRONT AXLE GEAR OIL LEVEL CHECK

M1262000900090

Remove the filler plug and check the gear oil level. Check that
the gear oil level is not more than 8 mm (0.3 inch) below the
bottom of the filler plug hole.

Specified gear oil: Hypoid gear oil API classification
GL-5 or higher [1.15 dm

DRIVE SHAFT END PLAY CHECK

M1261001400062

1. Jack up the vehicle and remove the front wheels.
2. Remove the hub cap.
3. Manually push the driveshaft in the direction in which it will

closely contact the knuckle.

4. Use a feeler gauge to measure the clearance between the

drive flange and the snap ring as shown in the illustration.

Standard value: 0.4

− 0.7 mm (0.02 − 0.03 inch)

5. If the play is not within the standard value, adjust by adding

or removing shims.
