Default DIff shot, dealer will not warranty... Help!

Hi everyone,

I have a 2013 GT track pack and about 10 days ago, I bought and installed steeda sport springs, Koni Yellow dampers and a Fays2 watts link. When I was under the car, I noticed a leak from the front of the diff, thinking it was the pinion seal, I assumed it would be a simple fix and proceeded with the job at hand. I garaged the car to not damage the diff right after the install.

Last thursday, I took it in to the dealership to have it fixed, this morning the service advisor calls and tells me there is bearing noise from the diff and that because the "aftermarket parts" lowered the ride height (1.2" really??) the pinion angle change caused abnormal wear in the bearing, and so he wont fix it under warranty and I'm looking at a $2000 bill!

I know the claim is totally bogus and it should be fixed under warranty, no questions asked. even if the condition was not pre existing, 1.2" drop can be caused by loading 2 people in the back of the car. What do I do?? my car is completely stock except for the listed mods and a borla axle back.

Take it to another dealer.

Another thought is to set it back to stock (providing you have the parts from 10 days ago). You'll spend 1/2 a day under the car (twice) but may save you $2000. Hell, even having the labor done for you should only run around $300-$500 - still a net savings.

Going through the fight of making them prove the burden of mods caused the issue will likely not be worth it. I think you have an uphill battle regardles. As one who has a similar suspension setup in the mail, I hope you get it.

They have a valid point, lowering the car will change the pinion angle. A change in pinion angle could create a leak from changing the stress on the pinion seal.

Problem is, you saw the leak and ignored it thus giving the dealer a plausible cause of the failure... Put it back to stock and take it to another dealer. I hope the dealer you took it to didn't put it into their Oasis system. If they did, their comments will be conveyed to the new dealership who may also deny the warranty work.

It doesn't matter that the angle can be that far off when you load people in the car, that would be with OEM parts. You changed the ride height permanently with non OEM type parts... Right or wrong, it is what it is. Good luck!

I don't have enough posts to PM yet, I've seen a ford service rep help out on the forum, can he/she tell me if I have a valid claim or I will have to pay for it? Thanks.

This post is spot on. You changed the pinion angle when you lowered it and now you may be SOL unfortunately.

You can try to contact them but they will probably give you a similar answer. Non oem parts could be to blame for the failure (in the dealer/Ford eyes). It doesn't matter that the leak was there before you started to replace the OEM parts with Non-OEM parts. They didn't see the leak before with the OEM parts still installed. Dealerships can only go with what's presented - A non OEM parted car showing a failure that could be attributed to the non oem parts.

No prior history to show otherwise, other than this post which was made after the dealer denied your claim.... see where I'm going with this?

Yeah, I realize that I screwed up, Like I said, I didn't think it was going to be a 2000$ rear end rebuild, even if the pinion seal is not covered under warranty it would have been a 100 to 150$ job. FML i guess... Yeah I do have the receipts for the parts I bought less than a month ago, if that would help prove I haven't driven thousands of miles with it.

Isn't the boss 302 lower that the stock GT by about 1"?

Isn't it a known issue with these cars that the diffs leak? I checked mine when I read about it and sure as **** there was oil on my diff. Sounds like you have a bogus service manager who needs to check the service bulletins.

Middle of last year, my pinion seal was leaking and replaced in a couple hours under warranty. I think the difference is, because of the modifications he has, he changed the angle of the differential which gave ford/dealer more then enough wiggle room to say, " Well, if you didn't add that there lowering kit, the angle wouldn't of changed an the seal wouldn't of leak / bearing noise wouldn't of happened."

Regardless if we know the pinion seals sucks, should've had it replaced prior to modding the suspension, especially if it was noticed before hand.

Um...no. I've never heard of pinion angle change causing diff problems, thats absolute bogus. If you use that vehicle to car pool 4 adults every day then your static pinion angle changes, that bearing is designed to take a lot more force then a pinion angle change. I've had car lowered for 33,000 miles and no leaks of worn bearings. Pay the 1hr diag fee take car to another dealership. When they warranty it submit both bills to Ford of reimbursement of diag fee from first dealer.

Thanks for the input everybody, just wanted to update to let you know I did manage to get it fixed under warranty, but the service advisor assured me he would not do it again and that this time was an exception. He also did not put any mention of the mods in the aftermarket mods in the Ford system (or so he says). Hopefully I won't have another bearing failure or any other diff issues in the near future. . So as a PSA, please take off any suspension mods before taking it in to a dealer to get warranty diff work. Once again, Thank you to everyone who took the time to reply.

Your dealer was really really cool. He did you a huge favor; you owe that guy a drink at the very minimum.

Granted, I agree that only a 1in drop is still within design specs of the pinion angle due to the operating range the pinion must endure such as going over normal road bumps, carrying passengers, or when enduring chassis squat during acceleration, but they could have also argued that the 1in drop also increased the operating angle range beyond design specs.

In the end, those guys want to keep your business; they treated you above and beyond what is right; you owe them by treating them right in return.

I'm not trying to tell you what to do; I'm just voicing my thoughts on the matter.

I've read a lot of posts about leaking pinion seals in the Mustang's 8.8 rear ... and our 2008 was always showing drops of lube hanging under the differential snout and it was obvious that it was from the pinion seal. I also noticed a slight hiss as pressure released when I was removing the fill plug to check level .... and it always started oozing out which tells me it was over filled.

Mine is out of warranty so I bought a new seal to replace it ..... but before doing so, I tried a change in vents to something more inline with what's under my several other Ford vehicles that don't leak. Stock Mustang rear vent has a rubber disc under slight spring pressure inside the vent's loose cap. It's a small hole in the vent, so it will take more psi to open the check valve than you might think.

I made a vent that attaches a hose that has a loop and is then routed inside the frame so no water ingestion .... but there's no restriction in the new vent. I used a brass fitting with a 3/8" hose barb on one end, turned other end down to tap it to fit the threads in the axle tube (7/16-20 sounds right). Clamped a short hose to it and a 3/8" copper tube with a tight U-curve in it, and then ran a piece of 3/8" hose from there down into a frame hole.

Not a drop of rear axle lube seen leaking since, the housing is now dry on the outside where there once was always lube hanging on.
