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, replace the axle housing.
WHEEL BEARING WEAR/DAMAGE
Because of the severe loads they must handle, wheel bearings may require replacement 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 inadequate lubrication. Without enough lubricant, the heated parts get soft and may eventually weld together. Check for lubricant leaks after repair.
