I would check u-joints. The back u-joint in my TR driveshaft went bad
and I put off doing anything about it. It ended up breaking the front
mounting plate on the differential. Snapped it right in two, but the car
got me home. This was a low frequency vibration that felt like a wheel
out of balance. With six u-joints, I can almost guarantee you have at
least one that's not up to snuff. Look for red rusty areas where the
spider goes into the yoke, one indication of a dried-up bearing.
