Hi Tom,
I had a similar problem for over a year, a nasty vibration 50-60 mph. I
of course checked the driveshaft by grabbing it and giving it a good
twist, which told me the U's were O.K. Kept Suffering, then last year I
stuck my hand in the access hole and started checking out the front
u-joint by feel and found that _all_ the bolts were loose, 2 to the
point of nearly falling out! It had still never clunked or produced any
rotational looseness (by the hand twist method, anyway)
Yours,
Dave
