MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
CAUTION
If a failure should occur in the differential, the loader must not be operated under its
own power. If the loader must be moved, disconnect the propeller shaft at the
transmission, or remove the propeller shaft completely. Drain both planetary hubs of
the noisy axle, remove the planetary covers, and pull the axle shafts to prevent further
damage. When shafts are removed, install planetary covers and fill hubs before
moving loader. The loader may be driven a short distance with one axle if the propeller
shafts and axle shafts are removed from the noisy axle or differential. Failure to comply
will damage equipment.
NOTE
Noise and vibration originating in the transmission, drive shafts, or tires is often
attributed to an axle. The source of noise should be investigated before deciding that
the cause is in the axle.
Axle noise may be isolated within the axle by jacking up the loader so the tires clear the
ground. If the noise is in one axle, disconnect the propeller shaft of the opposite axle at
the transmission. Now the noise may be isolated with only the noisy axle turning. Run
the engine at a moderate speed with the transmission in first gear. Both wheels must
be off the ground to prevent damage to the differential.
