the oem part does not constantly fail, its your lack of maintenance regimen which caused the joint to fail.

you did not check up on the boot condition regularly at 124k miles, allowing one to rip and allowed grease and grit into the joint which made the joint fail (not the entire axle). Had the joint not been exposed to the elements of the road because of the boot ripping the joint would go many hundred thousand miles with occasional repacking of fresh grease.

Rubber bits degrade and our CV boots are no exception, per a BMW tech on this forum the inner joints barely ever crack, because they are a different rubber compound, more of a plastic if you will, and they are suscepted to less movement compared to the outer joints.

At 124k miles it would be a normal maintenance item to check the condition of the CV boots every few months, it takes 2 seconds to look at them from under the car.

And if you read a few of the CV boot threads on this forum the consensus is about every 40-50k miles or so you will need a set of fresh boots.

Prevenative maintenance is key and a defect in the design of the "ultimate driving machine" isn't at fault here. With the cars age and mileage for all of our vehicles on here an ounce of prevention is worth a pound of cure.
