Possible U-Joint Problem?

[Hrspwrd]

I have a 99 GT and I'm noticing a terrible vibration especially when I'm going between 50-60mph. The entire car shakes and is really noticable in the steering wheel. I know it doesn't have to do with the brake system because I replaced all pad and rotors before winter and had the car stored. It really doesn't occur though until I hit at least 50mph. Other than a bad U-Joint up front, I'm not sure what else could be causing the problem? If anyone has any ideas/thoughts, I'd appreciate the info.

Thanks

it could be out of alignment, or you have a tire out of balance

if it eases up when you let off the gas i would say u joint , if it constant on or all throttle , it could be alignment , tire balance or wear problem , or wheel bearing

Yup definetly agree w/ 2002BLGT here on this one...if u only notice the vibration when you let off at like 50 mph its the U joint....replace front and rear while your under there if that is what the problem is.

Did you store the car for the Winter resting on the tires, or on jack stands or blocks?

Thanks Guys!

I appreciate the help guys......after driving it more I do believe that it is just a problem with alignment and/or tire balancing. I was having a hard time believing that my U Joints would go bad after only 36,000 miles. I stored it for probably only 1 month on the tires and then the rest on stands.
