I am working on a 42 chevy 3/4 pickup. When I drive it down the road at about 35mph it starts to shake really bad in the front end. It is also hard to turn the right. I have greased the front end which didn't help. I did raise it up on a rack and when I move the front tires from left to right I have no problem moving them but I cannot move them back the other way however when I lower it back down and the front end off the floor everything moves very easy with the steerng wheel. Any ideas to try.

Thanks

Bennie
