It is more like an out-of-balance wheel, not real bad. It is intermittent and is usually worse when I hit bumps/holes at about 65-70 mph. It has only been the "violent" type for just a second once and I backed-off quickly when it happened.

I recognized the symptoms from my dad's '66 3/4 ton International pickup of a few years ago. I used to just speed up to make it quit! The SD has quit with speed increase too but it's just not safe. I'm only using the SD for short hops around town right now.

I plan to sell the 240D and totally restore the SD.
