This just started recently but when I am driving on the highway (going 60mph+), the car vibrates really bad when I even barely turn the wheel either way. Also, if I am going 70mph or so and let off the gas and coast, it does the same shaking until i get down to about 45mph. Just started noticing this towards the end of a 10 hour road trip.

Any idea what would be causing this? I just got the wheels balanced so that isnt it. Im thinking maybe axles or something? Lemme know what you guys think. The car is a 97 3.2TL btw.

 

It might be your ball joint(s). My car was shaking pretty badly because both of my front lower ball joints were finished. You should check it out since if it is the ball joints then you will have some serious problems if they break.

 

mine used to vibrate around 60m/h but it went away after i replaced the harmonic balancer

 

see if your tires are balanced and/or inflated properly and see if your wheels are bent.

 

Mine just started doing the same.
