Just joined up today but I have a quick question. I have owned 5.0's before but this is the first one that I've had to deal with the power steering system. I have a leak coming from the part of the pressurized hose near the actual pump. But it is right where the rubber hose meets the metal extention piece that is connected to the pump. If you dont understand what im talking about, the metal piece is the peice coming from the pump that can swivel around. Now where the rubber hose meets the metal swivel piece, there is some kind of crimped clamp on it. It is obviously is doing a junky job so should i just cut this clamp and buy some new hose? also, where does this hose go? and also, will I have to replace the metal swivel piece or do I just buy the hose and slip it on and clamp it down?
 
welcome to stangnet, buy that hose at your auto parts store or the dealership but do buy the whole line, it goes connectec to the steering rack and is a pretty easy thing to do, take the two bolts that holds the rack and pull it out so it makes life easire to remove the line from the rack.
 
The return hoses are all low pressure and are most commonly secured to the pump and associated plumbing with worm gear hose clamps. After a while they will frequently soften up at the end where they are clamped, and should be replaced. The auto parts store will sell you hose by the foot and it takes about 3 feet or less, depending if you have the fluid cooler in the low pressure side of the line.

Each hose uses an O ring on each end to seal them. The hoses will swivel when they are installed and tightened into place. That is why there are O rings on the fittings. The O ring is the part that actually makes the pressure seal. If you slide the nut all the way back as far as it will go, you will see the O ring and the groove cut into the center section of the fitting.

Sometimes you will get some white Teflon rings with the pump or rack. The rings go on the threaded part of the fitting to reduce or prevent small leaks. They are not meant to seal the pressure part of the line or substitute for the rubber O ring. Heat the white Teflon seals in hot water and they will be easier to install. You can install the fittings without them and not have any leaks if the O rings seal good.

You may find it is easier to drop the rack down to get to the hose fittings. The flex coupling for the steering shaft needs to be disconnected before you can get the rack out. You should disassemble the coupling by undoing the 2 bolts that hold it together.

Remove the two bolts that bolt the rack assembly to the frame and then pull the rack down. Get a catch pan to dump the fluid in when you disconnect the hydraulic lines. I replaced the rack mount bushings with some Energy Suspension urethane ones. When you re-install the rack assembly, put the rear bushings in the rack assembly and lift it into place. Then install the front bushings & washers and tighten down the nuts. Doing it this way makes room for the hydraulic lines without having them bind against the frame.
 
ok, well return line are done but i'm a little stuck on the clamp on either end of the 3/8" pressure hose. basically, how do I get them off? I thought they were possibly threaded but they dont move and I dont want to force anything. here is a picture of what I'm talking about. any suggestions would be great. thanks.

The hose in the picture is a high pressure line. The metal ends are a factory assembled item, the are not desighed to be removed from the hose and reused.

All the lines disconnect in the same manner - you loosen the nut and then pull them out. See my previous post for a description of the O ring and teflon seal arrangement.
