i was explaining the setup for the front steering,but i forgot to about the pivot pot,and that is what you should deal with first.it is connected to the upper pivot link,well at least on the 9130 it is.and if the pivots are worn, you are goin to have a tough time getting it to center,but like les posted if it goes to the same side everytime then the pot probably needs to be centered.pretty easy to do,just takes a little time,and doesn't take much movement to change things a whole bunch.
