Hey guys, it sounds like the clamp on the pitman arm to me. What do y'all think?
@Popee, the pitman arm is held to the shaft by a bolt that has to be reeeeeeally tight to remove all lay from that connection. If not, it can shift enough to be noticeable in the steering wheel position. One minute straight ahead is perfect and the next it's off to one side or the other, depending on the direction of the last turn you took. It's unnerving, to say the least.
To fix it you need to get access to the bolt in the pitman arm and, using long bar to give you a lot of leverage, tighten it just a bit. Even one flat on the bolt can solve your problem. I fought this issue for two years before Leon Chupp told me what to do.
