My car is vibrating really bad around 80mph or just driving at high rpms. It sounds like the driveshaft is going to come through the floor. Any suggestions on what it could be or what to do?

 

Thanks Guys for the great advice! i just figured it out once again on my own.

 

LOL, I get that feeling around here sometimes too, but this isn't a very frequented forum.

Obviously something is not balanced correctly. I'm not sure how to narrow down what it is. First things first, check to make sure the weights on the wheel didn't come off.

If the wheel is still good then look around under the car. Sometimes you'll be very supprised what you find.

I'm guessing from the noise you should be able to tell which wheel/area of the car this is happening on. If not have someone ride with you and see if having multiple ears helps narrow it down.

 

Glad to hear that, btw that just reminded me having Snow inside of your rims after drifting on parking lots.

 

Well? What was it? Someone else may use the help too, you know.

 

sounds like ya gots a balance issue.

Tell us more about where you feel the vibration. In your hands on the steering wheel or in your pants. Have your wheels been balanced recently? Dirt rocks mud etc under the car? Excessive radial runout in the tires? Loose or improperly torqued drive shaft to x case bolts? Bent drive shaft?

 

could be as little as a balance or as bad as a tcase
