Why does the front of my 2004 Grand Prix GT Vibrate?

Answer 1

Either your alignment is off or your tires are out of balance. Try letting go of your steering wheel while going down the road at a fair speed. If it drifts either left or right, then it is your alignment. If it stays straight, you need your tires balanced. I had a camaro that vibrated once I hit 40 mph, and after I got new tires put on it, it quit.

Answer 2

Vibration is caused by a dynamic (moving) disturbance. Did you or anyone do anything to the tires? If so, check the lug nuts to be sure they are tight.
You may have lost a wheel weight. Weights are put onto the wheel assembly to remove vibration from heavy spots in the tire and/or wheel.
Did you hit anything?
The best thing to do is call the local ASE certified repair shops and ask what they charge to check it out. Most of the DEALERSHIPS will charge a minimum fee but Tire stores ans independent shops may inspect it for free.
Wheel balancing will probably solve the issue unless you have a bent rim or broken belt in a tire. Balancing is not too expensive. It usually is around $40.00.

Answer 3

While braking it would mean the rotors are warped, you can loosen the tires and torque the lug bolts to help this or have the rotors replaced. if it does this wile driving then I would look at shocks or tire balance. If it does this while goiong over bumpy road maybe look at the tie rod and steering parts.

Answer 4

If it's worse the faster you go, you need to have your tires rebalanced. You could have a tread separation in one of your tires if you hit a curb or pot hole real hard. Then the tire becomes "out of round" and will require replacement.

Answer 5

it depends could be that it needs tires,one of the steel belts could be broken. you should go to a front end specialst like sears
