I am totally a rookie, which will explain the comment I am going to make and maybe not using all the right terms. I had this problem once after I rebuilt my front end. After checking all of this stuff you guys have discussed, I found that I had not tightened the front drums down properly. They were basically loose and as you got up to speed the car shimmied terribly. I went back to Les's book and followed the instructions on tightening down those castle nut onto the spindle. Problem solved.
