95 gt 5 speed heavily vibrates in the freeway on 4th and 5th gear and it gets worst as I got faster . I've. Done some research and read that I can be the u joint drive shaft or harmonic balancer Idk I havnt checked any I will as soon as I get a chance . Anythoughts on what it might be guys ? I was also told by previous owner that the car has 375's in the rear end

Check the four 12-point bolts on the driveshaft and make sure that they are tight. If it's not that, could be a U-joint.

No it has nothing to do with the suspension on wheels there is no vibration on steering wheel the vibration is on transmision and rear end @ high speed

Sounds like a bad harmonic balancer... ![[patriot]](graemlins/patriot.gif)

had the same issue.. car only vibrated in 4th and 5th once i reached about 2500 rpm.. n would only get worse as i accelerate.. changed trans mount, dampner/harmonic balancer, etc but nothing helped.. switched the driveshaft and the problem went right away.. try borrowing one of your friends driveshafts or something and see if the problem goes away..
