Hi My names is James Miller,  
  
 I have an 1987 ford mustang with a 2.3 L engine. The problem is when the car reaches between 55 ? 60 mph it starts to vibrate severely in the drivers seat as well as in the steering wheel, but when it reaches between 70 ? 80 mph the vibrations go away. The first thing I thought of was that the rear wheel bearing where getting really bad and the vibrations were traveling, so I looked up troubleshooting the bearings and found that if bearings are getting bad the tire shaft from the differential there should be a little play when forced up-down-left-right, but when I tried, it was as tight as the book said it should be.  
  
 So I was wondering what you guys would suggest to be the next step in the troubleshooting process?

Alignment and tire balance could be the problem.

How were the tires checked? It sounds like a broken belt to me. That can sound just like a rough bearing. The car will have to be jacked up and the tires rotated slowly to see if there is any “wobble” to the tread.

I rotated the tires and the vibration didn’t change, but when I let out on the clutch the noise also stays the same.

You may want to check the wear on the tie rods.

I just replaced the tie rod ends, ball joints, struts, and brakes and calipers.
