I find it hard to believe that somebody that's an ASE Master Tech won't just fix it on their own. Why go through all the headache of rentals, lousy techs working on your car and being without your vehicle all the time? If the warranty is not worth the paper it's printed on then ask to get your ESP refunded and fix your own car! I never buy warranties because they're bogus.

Okay so the rear end is now officially toast. It is growling like you wouldn't believe. So loud inside that you can clearly hear it on the phone talking to someone. Take a look.

I dropped it off this morning. They of course gave me a super hard time about the rental even though I have coverage with Ford ESP.
They just called me back as I was posting this and told me to pick it up. They say the parts are National backorder and they are putting in a 5th ring gear and 7th bearing set.... I don't understand why Ford doesn't just send them a complete unit already.
Truth. It's time they pulled one off the line and got it packed up for shipping. This has been ongoing since when now?
You have any lemon law ammo in your state?
Seriously?
That's what I feel they should do. The growl is new, it was always just a whine before. But I knew it would inevitably turn into a growl as the gears were obviously not setup correctly. Anyway, now I just get to drive around with a messed up car as usual. YAY.... ... Its been going on since April of last year. I honestly just want the car fixed. I don't want them to lemon it.
Lemon it if you can and just get a new one if possible. Regardless of the initial physical maintenance problem, it appears that they (Ford collectively) have compounded what might have been an easy fix.
Here's your car back. We don't have the parts to fix it. Once we get the parts, we will call you. Only thing is: When you come back? We won't have the parts on hand to fix all the other stuff that's being torn up between now and then. Thanks for your patience. Please come again.
