i was making the 1200 mile trip home yesterday and i was on I40 and the car was runnin fine then i got bored so i started playin around and when i got to about 80 the car would start shaking and as soon as i brought the speed back down it would stop. it wouldnt do it under hard acceleration but if you would bring it up to a constant speed and it would start to shake, i pulled over at the next gas station and checked the tires and i aired all of them up to 40psi, looked under the car for anything loose and couldnt find anything, i cant figure out what it is but it scared the **** out of me when it first happend, any ideas?

Alignment, or high and low spots in your tires would be my guess. hows the insides of your front tires look?

Did you check if any wheel balancing weights have fallen off? That or alignment are my guesses.

sounds like a balance issue
