Default Vibration in Engine

Hi! I am having a vibration when I am driving at 70-75 mph. Is anyone else having this problem? I have a 06 GT. I took it to the dealership and they of course can't find the problem yet.

Thanks for any feedback..

details?

Is your car automatic?

Do you feel the vibration or just hear it?

If it is only at a certain speed and you can really feel it but then it goes away at a higher or lower speed, it's most likely a tire issue. Probably out of balance.

Could be your drive shaft too but you would feel it as you went through the gears.

I'm guessing it's a tire.

It is an automatic. I feel the vibration and hear it at 70-75. I go 60 or 80 and it goes away. I don't think it is the tires. Brand new.

I will go out on a limb here and say that it's DEFINITELY a tire.

Not all of them. Just one.

You have described a classic symptom of an unbalanced tire.

It's not a big deal at all. 99.9% of tires need a weight attached to the rim in order to balance it. Sometimes they come off.

Just tell the dealer that one of your tires is not balanced properly but you are not sure which one. They can "spin" them up for you in about 10 minutes. They have a balancing machine at the dealership. It's no problem at all.

Seriously, you have a new car, it should not have a problem like that. Tell the dealer that you are disappointed that they wouldn't even check something as simple as tire balance. Then look at them with that "look" that only women can do. LOL.

Let us know how it works out for you.

I agree too...

JUST because the tires are new does NOT mean they are ballanced correctly.

Also - I have seen out of round brake roters on new cars causing high speed vibration. So if the tires check out you might have them check that.

NOTE... your drive shaft also has to be ballanced. Look at it and you should see weights attached to it. If there appears to be a spot where one once was that can cause harmonic vibration at certain speeds.

I agree on the wheel or tire angle. Tire balancing if not done right can give you varied results based on speed and road surface you are traveling on. It's also the easiest item to check first. Im sure all the other suggestions are valid also.

There is a TSB for vibration at a certain speed for the auto. Look in the TSB and Recall header at the top of this page.

Edited this because my dealer is a Jack A$$ about fixing things. Print the TSB and throw it in his face. I have taken a printout of the TSB from this site to get everything on mine corrected. Funny how they can tell you they don't know why until you show them that Ford knows why. You would think they would just look up the TSB's themselves.

I have had similar problems with TSBs. The damn dealer won't even tell you about them half the time. [:@]

Thanks for the info. I will keep them in mind. Just got back cause they couldn't figure it out. Said it was my seashell necklace hanging from my mirror making the noise!! I started to laugh!! I had the forman go on a ride with me and he heard/felt the vibration. He thinks it may be the drive line. We will see. I will keep you guys posted. I want my car back!!!
