I unbolted 4 bolts that hold it to the frame, but then there is an arm that goes to a rod, the to the wheel. How can I get this apart? I don't see how to. I unbolted a bolt at the bottom of the steering box where the arm is, but that must be pressure fitted on becauyse it won't move. It looks like I am mangaling the rubber part and maybe other stuff where the grease nipples are underneath. HELP ASAP so I can finish for the day and come inside!
