I struggled with this most of the day yesterday. By far the worst part was trying to remove the pitman arm. Which required a special tool rental. (the pitman puller I bought was too small. Now if I could get the idler arm pressed and the pitman pressed back to the steering box, I could finish the rest in probably 30 minutes. The idler wants to spin in place when I try to torque the locking nut. The pitman arm is half pressed. I think my impact is not getting enough juice from my compressor. Ideas? I'm thinking of putting the steering box partway bolted back to the truck, and using the large wrench to drive the arm into place. The idler arm I went and bought a regular bolt. I'm hoping to use that with the impact the drive down the idler arm, then run the locking nut. Thoughts?
