Axles that have a harder bearing surface for one.............Maybe the bearings are wider to allow a greater surface area. Notice that it is fleet service, that would be hard, rough, not easy on the vehicle.
"2003 Ford Crown Victoria Police Interceptors and fleet vehicles"
" In addition, 2003 Lincoln Town Cars " That would be a heaver car, so it would need a heaver duty bearing and surface.
"the affected vehicles typically input higher loads into the vehicle chassis during fleet usage, overloading the wheel bearings and axles."
Some one just made a mistake on bearing loads for that axle for heavy duty use. Some time in the past every manufacture has made the same mistake, and you can bet that it will be made in the future on any make that any manufacture you can mention.
I just kind of wondered if ford somehow cheaped out on these to save a few pennies. This live type rear axles has basically been the same for how many years? You don't usually hear about this kind of failures.

hi bob - you are right. these axles have been around for ages.
i'm going to take a wild guess on this. maybe they are using an axle designed for less weight and lighter duty. look at the weight of the lincoln body and the police body. the manual on the police car says that the frame is over 25% heavier than the standard CV and if you combine the extra weight and extreme conditions these vehicles get put through, whether it is the lincoln towing a heavy trailer or the police car in pursuit is probably when the axle is failing. i doubt if they are just cashing in under routine conditions. but again, this is just a guess.

knowledge is power - growing old is mandatory - growing wise is optional "Many more men die with prostate cancer than of it. Growing old is invariably fatal. Prostate cancer is only sometimes so."
It could have been that there was a run of bad axles, nothing more.
Cheeped out may not be the right wording. Sounds like they are breaking which would be a mistake in manufacturing. I've seen alot of CVs axle brearings go out but have never seen one fracture. Also it says fleet use so that means cop cars-lots of abuse....
