Added C-beam plates when putting it back together so that is even more solid. So I still haven't figured it out... One thing I have not been able to do yet is to get with the FBI guys up north and try a completely different set of known good tires/wheels. One of these days hopefully I get time to do that...

BTDT...I think. I was getting a vibration - more like a "BUZZ" at speed. Did NOT go away when I shoved in the clutch, which lead me to thinking "drive shaft". So, I had a driveline shop install new SPICER U joints and balance the drive shaft. That CURED my "buzzing".

BTW, I have a set of stock wheels you can use for your testing. Lemmeknow if you want to borrow them.
