power steering loss

I have a 2000 Ford Excursion 7.3L diesel. The power steering has been whining for several years now but I've heard that is normal for these pumps so I have not thought too much about it. Today however, power steering failed and I have to stand on the brake pedal to get to stop. Stopping power is minimal so I had to be careful on the last few blocks to work. Is this a case of low fuid? I'm not familiar with anything mechanical so forgive me for asking. Where is power steering resivior located to check levels? Thanks for any help.

I'm fairly new to my `03 7.3 Diesel EX - but from what I've learned so far, it sounds like you have a bad pump.
It should be on the drivers side - in the middle - just to your right (if facing it
from the front) of the water pump.
The pump is also used as a hyrdo-boost for your brakes - which is why if the
steering pump goes out - you loose some of the brake assist.
There's only 1 o-ring that seals the resevoir to the pump, and if that seal goes
or the resevoir bolts work loose - you'll drip like a fiend and it'll do exactly what you mentioned.
I'll see if I can't snap a pic of mine to help you out.

I lost all power steering and braking while making a u-turn. Turns out my high pressure hose from the pump blew out while making the turn. I would check the hose coming off of the pump and make sure its still there.

My ps line blew pulling into the drive way. Lost all brakes and steering. Check ur lines and check ur cover for cracks. I test drive a truck that had very bad brakes and the guy lost his ps resivor cap so he put a rubber glove with a elastic holding it on lol.

U might just have a pin hole leak in the of the lines they like to rub on the shock tower that's how mine blew
