Are they saying it's normal, or are they claiming they don't hear/feel it? I had a dealer do that to me once with a transmission (different car). As soon as it exceeded warranty mileage, they could suddenly detect a problem that required complete replacement of my transmission... 馃槇
They said the noise and lurching was caused by the tires. They wanted $120 to try a different set of tires. I agreed to let them try it but I wouldn鈥檛 pay unless that fixed it. They took the wheels from another Mustang on the lot. It didn鈥檛 so I didn鈥檛 pay. They also said that I was running too much air in the tires because it was showing 37 lbs on the dash. It was a hot day and it reads the recommended 35 when cool. They also recommended that I should put an additive in the fluid and it would fix. I don鈥檛 understand why they are trying to get out of fixing the problem under warranty. Does Ford give the dealership grief about warranty work? This is first time warranty work for me.
I have an appointment with them in two weeks but I think I鈥檓 going to another dealership first to see what they say. It has 56,000 miles and this is covered until 60,000.

I'm beginning to think there aren't any real mechanics left at dealerships any more. I hear the most bizarre statements made by obvious morons, and we are supposed to trust their diagnostic ability with the most expensive thing we own! If the computer doesn't give them a code, they don't have a clue what to do. o_O

Hello guys, just joining this forum/web

I also bought an Ecoboost a few month ago and it started to make a rubbing noise similar than you explained. In my case, the noise is made when i am turning and pushing the gas at the same time. If i am turning with no gas, no noise. After a while (10鈥 driving or less) the noise disappears completely, what makes me think it is doing it just when it is cold (leaving in NJ, cold but not freezing by now). Before the delivery, the rear differential was replaced. The car runs perfect and this noise it is not affecting any aspect of the drive, so I do not know if it is related or not. Any ideas?? I should try this friction modifier I have been looking as a solution?

Right now the car is being checked by a mechanic (under Warranty with Carvana), so they are diagnosing it (they replaced the rear shocks because they thought I complained about another noise.. under warranty too lol, so with new shocks it was still doing it, I think they are a bit lost by now).

Hey guys.

I've had the same issue, weird "bass" sounds were heard while turning the steering wheel and pushing the gas. I visited the technician and he said that's a common problem for LSDs. I replaced the differential and its gone... 馃し馃徏鈥嶁檪锔
