I finally got the leaf springs in and the pinion angle set. Much, much better!! Still a very slight vibration though. I had the rear wheels balanced and they were off considerably. Reason being is the belts are slipped or broken. Balanced the tires and vibration is almost gone. I am sure that the rest of the issue is the tires. So, I will put a new set on and be done with it. They are old but have little miles on them. I wonder how many guys are running old tires and have issues like this assuming they are good. When we spin balanced them you could see the rim run true and the tire run out of wack. Thanks for all the help guys!! Fun to drive this again. Hasn't been this nice in years. Can't wait to get the new tires on now!
