alright, the spot where the drag link hooks to the knuckle arm has like an inch of play in it and is in bad shape. this would make the Black Fear shake the way it does i believe. 
thanks fo the link oops. hopefully this is it cause i hate driving my chevy.
There are adjustments on both ends of the draglink. You can also get rebuild kits for the DL ends. dealer item I think, do not know I have never bought one.
