What do you think of the brown coat on the differential/axles???? (is this normal???)
The driveshaft has a ''darker'' looking rust color (brownish) something looks off on this car!!

Even in the engine bay I wiped my finger on the engine block and some ''white'' residue wiped off onto my finger!

The headers look somewhat rusted aswell and it looks like somone was chewing on the engine block at the factory with all these little dings!?!? (looks like the header is also missing a bolt going down to the exhaust)

(car was 6/2013 with 40miles @ FL dealer)

Hopefully it's just this car as I am about to custom order one and will be PISSED if it's flawed like this!!!

 

It's just surface rust and it's normal. Not sure about the missing bolt.

 

how about the engine block??? it looks like micro cracks lol...

so that ''6 month old surface rust'' is normal on the header?

 

This made me laugh.

 

Absolutely nothing out of the ordinary on your car, they are all like that.

Only cars with a painted rear axle housing is the Boss/Track Pack/GT500.

And the crazing in the aluminum castings are normal too, just the way they come out of the molds. The white residue is just surface oxidation and is also normal.

And I see no missing bolt on the exhaust.

 

I agree, looks 100% normal

 

That's a cast iron exhaust manifold, and cast iron does rust.

But it's just surface rust, it will never rust out.

 

Sorry this was my first in person up close and personal view of the car!

On another note when test driving (GT guys must feel x2 what I did) the V6 it was actually quite responsive.
Limited testing space and anxious sales man but just a wee bit of gas and your off..

I was worried about those things but if they check out then I feel like a noob for thinking something was ''wrong'' lol

 

that "missing" bolt faces downward perhaps?

 

It's normal surface rust but still not a good feeling.

 

This^^^
The Exhaust manifolds have a stud and the exhaust is bolted in from the bottom.

 

I also was shocked the first time I discovered the rear diff and various other metal parts under my new 2014 GT were rusty like that. Every vehicle I had bought up until this time with a solid rear axle, had painted axles so I was surprised to see an unpainted and rusty rear axle on a car costing over $32,000.


I never looked under the car when I was looking to buy so I didn't discover it until I went to install my Roush AB. I may paint mine at some point since I don't like how it looks but who really sees it under there anyway?


Here is what my rear axle looks like. I added the aluminum diff cover.

It looks terrible and I actually got under their (was not ready or expecting to see this) was to take a picture for a thread I read on here about someone buying a GTsomething exhaust and thought it was used

When I saw that I couldnt believe in only 7 months it could have rusted then I saw the header and the engine lol...

 

Even with the Track Pack there are unpainted metal parts under the car. They surface rust instantly. My car has never even seen rain... Just water from washing and Summer humidity. Surface rust... Nothing more. I will probably try to paint some of them this next Spring.

 

Same deal on mine, rusty as hell. Is Ford using the cheapest parts in the world or is all cars like that down there?

 

The parts will last beyond the expected life expectancy of the car without paint so Ford saves a few buck on the cost of building the car.

And the rear axles are usually rusty or at least partially so, when they are installed at the factory, reason being, is that the housings are stored outside before production.

Don't like it? Want a permanent fix? Just get some POR15 paint and crawl under there and get to work coating all those rusty parts.

 

Wow .... What a bunch of crybabies. Stop looking under your cars and drive them.
I've owned Fords for 40 years and they have always had rusty axles.

 

My car was six months old with 38 miles when I bought it. It was built in 2/2013 and you could tell it had been driven on some salty roads as you could see some of the salt residue on the underside of the car.


After I installed my Roush AB, I wiped down as much of the underneath as I could reach with a wet rag to get the salt residue off. I also later used an under car sprayer that I have to rinse things off.

my 09 is still undriven- 5 yrs old, 4.9 miles (had 3.4 when flatbedded from michigan- move it around once in a while), anyways it got wiped down with oil when i got it home, axle rust is minimal, eventually will paint it...used a light spray oil on the block/tranny while the motor was warm, let it sit a few days before warming up again, so far thats kept the white aluminum oxidation at bay. only corrosion on the car is the front hood lip, like most others... its only gotten slightly worse than when new, but has expanded a little bit. I'm going to mask it off and use 'goop' sealer around the underside hem- lots of thinkingabout sealing options, but that stuff remains flexible/fuelproof/clear for a long time and is thick enough I *think* i can make a decent looking bead- but its really stringy stuff, masking needed to keep pull away threads from getting on the paint...enough toluene it should bite hard into the paint under there, and bond/seal the razor sharp edge (I still think fords 'iron contamination is BS- just shoddy work on a non-deburred hem joint without seam sealer)...worst case I'll ruin a virgin hood.

the worst thing about the unpainted axles, if you have a cement driveway, it leaves rust stains where you park- if you park outside in the rain anyways...

my son got a california expedition (2000) that was ultra-clean underneath- what surface rust there was, we just ospho'd and used eastwood rust encapsulator spray paint on- a lot less messy than POR15, but fast/easy... he did use POR up front, but made such a mess we decided it wasnt worth it...if disassembling, wanting a lifetime paint, POR15 is the way to go- but for just coating assembled parts, the eastwood stuff looks pretty good- and its semigloss, easily touched up/overcoated unlike POR. I'll probably ospho/eastwood spray encapsulator the 09 axle/driveshaft, brush/dab encapsulator on misc bolts, control arm weld seams and such.

I tore my 06 apart when new, the wife came out to the garage, saw the interior out, fenders off just shook her head and went inside... I used heavy paint, injected every vertical pinchweld, when paint seeped thru between welds, taped up to fill all the voids, only left the lowest drains open... theres a 'scoop' like thing under the fender/behind the headlights that blows roadspray directly into the upper unibody, it has to run all the way to the lower 'frame' to drain, leaving dirt along the way to clog things up... I made little plastic 'reverse scoops' and just glued them over the openings with seam sealer, so the thing can still breathe, but not recieve water from the front. kinda goofy, yeah, but i tend to keep cars forever, and really hate rust... will do the same before driving the 09 (really might do more harm than good if done after its been driven/collected dirt inside), hope to never have to do any cutting/welding on them down the road. my wifes has been on salted roads at least once, she didnt want me 'messing with it' but even at 20k mile 07 hers looks old underneath compared to my 60k mile 06... just wish I woulda oiled the cast aluminum before driving my 06 much- the white engine looks like crap. the oil darkened the color a bit on the 09, but it seems to have stopped the surface oxidation, at least for its 5 year nap...

 

Geez. Are you saving that thing thinking it'll be worth a fortune or what?
