[FWDLK] Bad Vibrations

["St. Clair, Todd" <tstclair@xxxxxxx>]

Had the car out lastnight. I am getting a severe vibration that starts at
45mph and
goes away at 65mph. Any suggestions. I am leaning towards a u-joint problem.
The front u joint(ball&trunion) looks like a joy to work on. The rear seemed
ok last time I checked it. I just don't understand why at only these speeds
I have the vibration. Could it be the bias ply tires bulge out to due
centrifugal force and change the pinion angle at these speeds (I like this
theory!)? Putting the trans in neutral has no effect. Are U joints readily
available? Looking through the stacks of reciepts from past owners shows a U
joint from an 84 Jeep being used at some point (could be the one that's
still on it)

      Thanks
