OK--- here's my 2cents .... if you do use the 'pitman arm puller' ..... and are going to re-use your steering box (or re-use your sector-shaft) ........ THEN, before you use that puller - install the "shaft-nut" back onto the lower shaft ... just enough to protect those threads.
why -- because by using that puller , you may Mess-up your shaft threads (mushroom the end of that shaft -- been there), and then won't be able to re-thread that 'nut'.
Same thing about your "tie-rod end" ... however, most of the time ... you just replace those tie-rods anyway ...... so, not that important (as, where your 'sector shaft' might get reused -- if it's in good shape)
either way looks good --- with the puller or by cutting & impact gun.
I've done each.
Thanks for the video.
