I've never seen a passenger car axle break. I've seen rear housings broke in accidents, seen 1/2 ton PU bearings crushed into the axle from overloading, seen them come out from bearing failure, but never actually seen one break...
Like to see some pictures when you get it out. Bet Ford would like to know about it too!

Ford had a nasty habit of making rear axle bearings wothout an inner race, so the rollers wore directly against the axle, weakening it. For axles caught before total failure they maken "axle saver" bearing, and for those not, the axles are not too expensive as many are sold. You probably have of of these.
Sorry, bad design.

Got to thinking ,, I can tell this Lincoln had some minor body repair work done to the passenger side , and am now thinking that the rear axle took a pretty good shock hit., therefore cracking the axle .... did not realize that til after I bought the Lincoln at auction ,last oct , at the time I thought I got a hek of a deal , I am thinking not so good ,,.,now , here goes the laundry list , the heater core was disconnected because it leaked , fixed that with dike from napa ,, so far so good,,.wiper motor was burnt up too ,, not that big a deal to fix ,,then kept smellimg coolant ,, turned out the plastic manifold FORD MISTAKE was porous..put jb weld on it , worked for a month then , the manifold crackt around thermostat , all the water must a messed up a coil pack ,

Is it Black? If it was a limo/airport transport unit it could have been used hard.
Also a lot were owned by old guys that liked to drive over curbs. My 85 year old aunt has knocked the rear axle sideways in hers. It now dog tracks down the road, but she hasn't noticed it yet.

I have seen this before on Lincoln's and Crown Vics. The right rear axle bearing cuts through the hardened layer of the axle, then wears a groove in the axle. The noise is then ignored until the axle is cut off or other bad things happen. Likely your housing is ruined, as the bearing usually spins in the housing, removing the press fit on the outside of the bearing. None of this is Ford's fault, this car is 15 years old. If anything, cars are more durable now. Think of how worn out a 15 year old car was 20 years ago, it would be rusted up to the door handles. It is not in a companies' best interest to make a product that lasts forever. As others have stated, this design is/was used since the 60's by the big three on up to light 3/4 ton trucks. Auction cars are not usually a good deal, that is where dealers dump cars they don't want to fix.

While it's possible for anything to break I would bet that axle took a pretty hard hit sometime in it's life. While I don't care for the plastic intakes at all my guess is your engine has been overheated enough to ruin it when the heater core went out. No engine likes overheating and there's alway's damage when it happens.
Bell Helicopter runs the output bearing of at least some medium weight helicopters against the main rotor mast. It is not necessarily a bad design, it just makes repair more difficult.
By omitting the inner race, the rolling element bearing can be significantly bigger and stronger. Note the word "can".

I'm don't know when they switched rears for cars, 80's I guess, but the old Ford 9 inch used a tapered roller on the axle with inner and outer races.
No doubt this newer car is using the 8.8.
Other than getting hit at the dirt track I haven't seen a GM axle break. I've seen plenty of them that were badly grooved though and it certainly seems like a good place for a crack to start.

There's a couple years (1998 - 2002) that the 8.75 rear end used in the panther body style had issues with the rear axles. Police cars had lots of failures.
One other thing to look out for - that year also used an all plastic intake manifold - after a few years it cracks leting all the coolant run out onto the ground in a few miles. Ford never recalled them but made a "correct" replacement with steel reinforcements that was used on the later models - earlier models used an aluminum intake. Cars that saw hard use would fail after just a couple years, cars that don't get driven hard or revved hard (alternator bolts to the plastic intake) lasted a lot longer - but eventually they all fail. About $600 to replace at a dealer.

The plastic intake manifold on the 4.6 used in the panther body style is notorious for failing. After some time it gets hard and brittle and over revving the engine will cause it to break - most happened within the first 40-50 thousand miles. 1991-1997(?) uses an aluminum intake, 2004(?) and newer uses a plastic and metal intake, the replacement for the plastic intake is plastic and metal.
My 97 town car had the manifold go out and it cost over 800 to fix at a dealer and that was a few years ago. The wheel axel bearing went out on my 2000 Town car and it cost over 1100 to fix, and then it went out a year later but I got lucky because the new one they put in the year before is guaranteed for life. I still think Ford designed these just to screw the people. My new car will be something I never thought I would do, But for retirement why not ?/ A new Hyundai elantra. 40 MPH 100000 mile warrantee and easy to park. And cheep. And I am still going to vote for old nnalert.
