Ted,
What tires are you running?
I had VERY OLD bias ply tires on my 46 when I bought it. The truck had been parked in the same spot for so long, the tires would never return to round. The truck shook so bad in a curve that it would just about throw the truck off the road. I bought new tires and the problem was fixed. One shock link was off at the time, but with new tires, it did not matter...it rode 100 X better.
