Mechanical thoughts? Update added at the end.
Yesterday headed out in my 1995 F 250 2WD 5.8 L automatic and got about a mile before the power steering no longer worked, I kinda heard something not really sure how to explain it... anyways put the truck into park got out and walked around and didn't see anything out of the ordinary, no leaks, didn't see anything i might of hit... got it back home about a mile or less slow speed man handling the thing to make several turns. Checked the dip stick built in to the cap on the pump and it was pretty much not showing any fluid... I don't have any fluid Power steering or ATF to add and it's too cold and nasty outside to get any today, what are the chances it just needs fluid vs. a new pump, etc.?
