In 1st gear, if i floor it, it wobbles, you can feel the vibration under the car, but other gears are fine. And when cruising on the highway going 120, its constantly wobbling. At first i thought it was my one of my tires, but when i let go of the gas and put the car in neutral, it goes away. Couple nights ago, it got real bad, it felt like something was gonna snap, i had to slow down and it went away. How do i fix this? Has anyone experienced that before? Is it safe to drive the car like that as long as it's not wobbling or should i get this fixed ASAP?

Any help would be greatly appreciated.

Thanks,

Sebastien
