Stiff Steering After Pitman/Idler/Box; 2WD vs. 4WD Steering Pump Difference?

[Rocket Man]

I’ll be sure not to use Proforged parts although I only use ACDelco or Moog Problem Solver anyway.

Are these the 3 parts I’d need to do pitman and idler then? I never go the cheap ac delco
45C0069
45C1123
45C1120

also, do I need this:
OTC Puller, Pitmanarm, 2jaw - 6496 https://www.amazon.com/dp/B00061SMEE/ref=cm_sw_r_cp_api_i_YtgPEbJ2PG5WV
or is this really only for 4WD guys? I know it speeds up the process, but is it only 4WD process, or 2WD as well?
