Default Vibration when lifting off gas pedal

Hi guys,

I just noticed that whenever I lift my foot off the gas pedal only above 80mph, I feel vibration throughout the body of the car (I feel it on the seat). There is no vibration on the pedal it self and steering wheel.

Do yall have any idea what is wrong?

Thanks!

The car is fine when braking and cruising below 80mph. The vibration was only felt when I lifted my foot from the gas pedal above 80mph.

Could it be the drive-shaft?

I had this on my car when I drove with unbalanced tires and no hubrings (on Vossens). Once I mounted my wheels back on the vibration no longer existed. I'd go get the tires rebalanced.

Would you recommend me to get the hub-rings? I will rebalance the wheels as well.

If you have aftermarket rims then yes.

I have OEM wheels. I'm still not sure if the wheels are the problem. My car is fine above 80mph with foot on the gas pedal. Are yall have exactly the same problem (only when you lift your foot off the pedal)?

But I will rebalance them anyway.

If you're on your stock rims just rebalance them, hubrings wont even fit on lol.

I just had this problem last week. lol

It was that my front two tires needed to be re-balanced. Now it's solid.

Another issue is you have a bulge in your tire....but with this you should feel vibration and steering wheel shaking at certain speeds while your foot is on the gas pedal.

I know this thread is really old but did balancing your tires actually work for you? I have the same issue and did that and it didn't help...
