I have a 03 Cavalier.

First my car was shaking when i would accelerate up to 60-65mph. I took my car in and had them balance and align my tires and check for bent rim. All checked out fine.

Now when i am driving at highway speed of 60-65 it will start to shake then stop for a while then start shaking again.

If it does do this at lower speeds i am not noticing it. At higher speeds i definitely notice it, but it is not doing it the whole time i am driving at 65. It is really random.

Any suggestions?

 

it could be a bearing,cv joint, tie rod end , but i say a bad tire put the front on the back[both] see if that helps it can also be a input shaft coming out of the tranny i try the tires first if it keeps on then check all the above
