need help quick.. power steering quit, and some other problems too

[CherryColaholic]

Well as the title suggests my power steering has died. i was driving home from work on the highway and just outta nowhere i noticed the wheel get heavy. I didnt think too much of it until i got off the highway. I could barely turn the dang thing. I used to have a car without power steering and it was ten times easier to turn that than it was to turn my bronco today. My first thought was obviously to check fluid. It was a bit low so i topped it off. Still heavy as snot to turn the wheel. Belt looks okay and was not slipping at all. Thats as far as i could get since i didnt have my flashlight. Im too mad at it right now to go back out and look with a flashlight now that im home. So.... is my pump dead? Could anything else cause this? I also noticed that when i have the clutch pedal all the way down theres like this clunky sound. Im even a car guy and ive never heard anything like this sound.. heck i cant even describe it better than a clunky sound that i think is coming from the front of the tranny where the clutch is or else under the hood somewhere. I dont know if thats a problem or not. I dont know if its related. Also.. how much does it cost to have a front wheel bearing replaced? I dont have have a press and i dont feel like doing it anyway so i just need to know about what its gonna run my to have somebody else do it. Well any help you guys can give me on any of these three questions will be greatly appreciated. But my main concern is the power steering. I gotta be at work by noon.

Okay, the pressure line coming out of the pump was completely out. I pushed it in as far as i could but it only goes about halfway back in. But besides that, im thinking that if it was able to come out then the flange is probably messed up so i would need a new hose right?

Dont overtighten the new hose as theres a standpipe in there, dont want to bend it.

What does your Haynes manual say about the noisy clutch?
