pitman arm question

Yes. You can loosen the steering box nut or remove alltogether. The pitman arm won't fall off easily if the nut is off the steering box. The old pitman arm can also remain attached to the old center link since your scrapping both. Keep pitman arm on steering box until last, you may need the Centerlink stable and not flopping around if you need to use a pickle fork to detach the ball joints.
Take a pic 1st and mark the orientation of the Pitman arm on the splined shaft before using the puller. Makes it easier to orient the replacement arm in the correct spline.
