As far as the working angles of the u-joints are concerned, I removed the shim I put in to lower the center carrier support and it's all as it came from the factory now. Stock ride height. No change in the vibration. Still fighting it. Wish I had access to 2 stock steel rimmed tire assemblies. I would love to bolt them on and see if there is a difference, once and for all eliminating tire & wheels.
