Analysis of Inoperative Conditions

If the axle does not operate, one of the following may be the cause.

Broken Welds
If the differential housing welds are completely broken, install a new differential housing.

Wheel Bearing Wear/Damage
Because of the severe loads they must handle, new wheel bearings may need to be installed at high mileage. If a wheel bearing fails at low mileage, it is often caused by overloading.
