shaking 240

[nism0240]

somethings wrong with my car. heres what happens...0-55mph the car is nice and smooth. at about 60-75mph the car shakes so much it feels like its gonna explode and it chatters my teeth. BUT after 75 i can go as fast as i want and the car is back to normal. what do you think is wrong with the car? bad mounts maybe? engine needs to be balanced? i have no clue...

is it an automatic? does it only do that on a certain gear say the 4th?

Where is the vibration...the entire car or just the steering wheel??

go get your tires balanced and your allignment checked

if not what was said above, I would say bad mounts

Does your steering wheel shake? If so could be your tc rods or tie rods. Also check if your LCA's are straight.

Try this first:

re-tourque your lug-nuts.

I had a shake that was driving me nuts, replaced several parts, didnt get any better, replaced the wheels, it was better for a while then came back, but the original wheels back on, shake went away then came back. I torqued the crap out of my lug nuts, and now I have no more shake.
