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
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
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."
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....
