Bad IWE broke transfer case?

RDFTS said:

@FordTechOne, let me ask you this. Can a failing IWE on a 100% stock truck cause the transfer case to fail because of it?

Not something I've ever seen. I don't see a correlation.

Exactly, and that is all the OP was asking.
Regardless of his mods the dealership should of chosen something else to blame than saying the broken IWE caused the transfer case to fail. Telling the customer that just makes them look like idiots. He might as well said because the motor on the seat failed, it caused the transfer case to fail.

You are one of the rare folks in the country that still gets all of his stuff replaced under warranty despite having aftermarket shocks, UCA, tie rods, and so on.

Ford stands behind their warranty for their engineering, their design, and their parts. I have never personally seen in all my years a warranty claim denied when a stock vehicle was being used for it's intended purpose, whether that be a GT500 or a F-550. If the dealer played games, the Field Rep made the right call 99% of the time and had it warrantied. They are not, however, going to be responsible for failures attributed to aftermarket modifications. That is true with all OE manufacturers, don't kid yourself into believing that is unique to Ford.

I have had many other brand trucks and have never had a warranty claim denied unless it was directly linked to a modified part. 2 different times on 2 different trucks Toyota replaced my cv shaft boots even though my truck was slightly lifted. I was expecting to pay but they warrantied it. I’m not saying technically a modified suspension can’t put more stress on a drivetrain due to the cv shaft angles but when the housing cracks breaks I call shenanigans on the front being slightly taller causing that. I respect your opinion but I don’t feel that Ford stood behind their product in my case. The Shelby raptor has the same shocks, set at the same height and is sold new through Ford dealerships. I understand Shelby isn’t Ford but they work very close with Ford and I’m sure if it would have caused any questionable damage they wouldn’t have put it on the truck. In my experience Ford is absolutely not on par with other brands I’ve owned warranty wise (Toyota, GM, Subaru, BMW) and they sure won’t be getting my money again. I love my truck don’t get me wrong though I just am bitter with Ford for making me swap a new diff in my driveway around Christmas haha!

Your statement exemplifies the variability between dealerships. If a Toyota rep had knowledge of your vehicle, it's highly doubtful they would have warrantied that issue. Let me ask you this...does the RO you received state that your vehicle had a lift? Of course not. The dealer in your case was more interested in profiting from the warranty repair than abiding by the manufacturer's warranty policy.

Why were you expecting to pay for the failed CV axles on your lifted Toyota but not expecting to pay for the front differential on your lifted Raptor? All CV joints have a maximum operating angle; it doesn't vary by vehicle. The higher the angle, the more torque is placed on the drive/driven assemblies (axle housing/wheel hub). Even though the Raptor has a wider track than a standard F-150, the axles are still at a higher operating angle than a standard truck. A lift only increases that angle and increases load on the components on each end. Cast housings (typically) break in one of two ways; they either crack along a casting line or crack in a random pattern. A crack on a casting line likely indicates a faulty casting. A crack that has no originating casting line is typically from stress.

As far as the Shelby Raptor, that is not a Ford product. I think you are confusing Shelby/Ford with Shelby/Tuscany. The Shelby/Ford licensing is completely separate from the aftermarket Shelby products. All Shelby F-150s are modified by Shelby American/Tuscany in Las Vegas. Not a single drivetrain part on that vehicle is covered by Ford warranty, which is the reason that Shelby/Tuscany provides their own warranty. Those trucks are purchased by Shelby/Tuscany as "ship throughs", modified by Shelby/Tuscany, and then sold to dealerships for retailing. Shelby/Tuscany is responsible for every single modification on those vehicles from the interior trim to the powertrain components. Same goes for any other aftermarket/dealership modified vehicles. If a dealership claims otherwise, they are committing warranty fraud.

Please don't think I'm not empathetic to your case. If I was in your shoes I certainly wouldn't be happy either, especially if you truly believe that the issue was the result of a defect (entirely possible) and not your modification. Its miserable to have any powertrain component failure on a vehicle, never mind one you have to pay for out of your own pocket and replace with your own labor. I'm just trying to explain the dynamics of the industry, which cannot support case-by-case failure analysis for reasons I mentioned earlier.

With Toyota it was a CV boot that failed not the actual CV and the amount that my truck was raised was quite a bit more percentage wise than the raptor compared to stock. Also the Toyota's were known to rip boots when lifted at all so that's why I expected to pay out of pocket. And I do realize that Shelby is a different company as I said in my post but I still feel like they are close enough with Ford, and an established enough company (as is FOX for that matter) to test and know what would cause potential damage to the vehicle. And as I also said I am in no way saying that lifting the front of the vehicle can not cause stress on the diff, but the amount it was lifted should not have caused my diff to break like that and I still do not feel that that was the cause of my failure. But it's done with and because of it, setting aside the fact they didn't honor the warranty, I personally did not like how Ford dealt with my case (honestly it was the worst customer service experience I've ever dealt with) and because of that they have lost my business. I really do appreciate all the info you input to the forum by the way! It's just my personal feeling about my whole situation. Anyway I guess we should get back to the OP's issue. I hope everything goes better for him!

“Lift” or “level” ****** block kit/collars or springs? Springs should not alter the angle of the axles...blocks under the stock springs/shock mounts tho? Yes

Didn't you say you bought the truck second hand?

Any lift that is not a body lift ie spacer or shocks/springs will alter the cv axle angle.
