I just bought a 2009 Ford Expedition XLT. when I drive

Customer Question
between 30-40 mph there is...
I just bought a 2009 Ford Expedition XLT. when I drive between 30-40 mph there is a mild vibration/grinding type sound. It almost feels like you are going over rumble strips but without the noise. I've tried looking it up and sites I've found have suggested anything from using a different fuel type, to an oil change to a transmission problem. Any ideas?

Hello, if you drive faster does the noise get worse?

No, it goes away, it only does it off and on and only between 30-40 mph
Ford Mechanic: James, Ford Technician replied 2 years ago

Does it make a difference if you are accelerating or coasting?

What Customers are Saying:

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

MollyUSA

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.
