This is an 1984 M1008 CUCV (K30) Has a 6.2L diesel with 12v conversion (so only one belt to power steering pump) and hydroboost brakes. I have no power steering but the brakes are fine. Seems like just manual steering or at least very little power assist. the slower I move the worse it is and you can forget about turning the wheel at a stand still. no squealing or groaning noises that I can hear (but it is a diesel) fluid level OK, Belt seems OK but it it hard to tighten with a stupid 3 bolt configuration, I am inclined to replace the pump first since it is cheaper, but was wondering if you guys thought this could be the steering box. Thanks in advance for any advice.
