In my 85 SVO, I had a low speed vibration with the original drive shaft. So I installed an aluminum drive shaft and picked up a high-speed vibration with the new shaft, around 55 to 65 mph. The low speed vibration is gone and I think the problem was coming from the U joints. No visible dings on the new shaft and I havenít checked for balancing yet. I have been told that some people donít like aluminum drive shafts, but never was told why??? I know Ford installs them in factory cars & trucks, so why would people not like them?

Aluminum driveshafts work great. Lighter and easier to balance. I would try a simple 180 degree spin at the rear flange and see if that helps. You can try 90 degrees at a time also.

You might have just unmasked a different source of vibration by getting the aluminum drive shaft. I would have your tires balanced and see what happens.

It's not a tire type vibration, it's a faster driveline type of vibration....
