2003 Explorer Jumpy Steering
I have a 2003 Explorer V8 just turned 115,000 and about the same time it rolled to that the power steering became jumpy...loose steering than hard steering as I go around turns, fun at 65mph when all of a sudden you go to an under steer, also when standing still. No sound out of the ordinary from the pump. So does anyone else have this? I am figuring power steering pump, but I figure I see what everyone else thought, Thanks

Has not been towed, pretty careful about steering while not moving/engine off. I popped the top and the fluid is pretty burnt. So I got some ATF and will be trying to get out as much as possible. Let you know. Thanks again.

Use a helper, engine running, add fresh fluid to pump as helper turns steering lock to lock, engine at warm idle. When fluid from return line is red/clean, shut down and reconnect line to pump, top up pump reservoir
Burp steering rack by slowly turning steering lock to lock, wheel off ground.

a normal ford ps pump is kind of noisy and whinny. I think you said yours make no real noise at all. maybe the pump is strip and not really spinning. i would repalce the pump it takes 30 minutes tp swap and i think i bought mine from AZ or advanced 2 years ago for $23......
