Analysis of Inoperative Conditions

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

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

Wheel Bearing Wear/Damage
Because of the severe loads they must handle, wheel bearings can require installation at high mileage. If a wheel bearing fails at low mileage, it is often caused by overloading.

Axle Lock Up
Lock up or seizure of the axle shaft usually indicates that something inside the axle has broken or is welded together preventing component rotation. Lack of lubricant will lead to overheating and, ultimately, the components welding together or breaking.
