I litterally just did this yesterday. The book will tell you to remove the entire rack, but you dont need to. Use a floor jack and place it in the center of the front K-member cross bar. Jack up the car untill the front tires are off the ground, place blocks of wood back behind the front tires on the frame rails so it will support the car when the jack is lowered. Next remove the air box, dog bone mount, and both fans. drain about 1.5 galons of coolent from the radiator. Take off the hose that runs from the radiator to the thermostate, and the little hose that runs above the water pump right next to the exhaust. Remove the hose that goes into the water pump. Now, go under the car, you will see four huge bolts that hold up the four corners of the engine craddle/ K-member. They are about 6 inches long. Take the back ones out about half way and the front ones all the way. This will allow you to roll the engine forward so you and get to the lines. You should now be able to lower the jack and it should allow the engine to roll forward, use this to your advantage, rolling the engine forward will help you gain acess to the lines. SLOWLY lower the jack and watch to make sure no lines attached to the engine get streached (I had to disconnect the crusie control). After lowered so far you shoud be able to see the lines, they are right next to the steering knuckle. Remove them with line wrenches and replace the one that is bad. After they are replaced jack the engine back up in place and put the engine craddle bolts back in. You shoud not have to bleed the lines since the return line will force any air out. Just put everything back and fill your radiator and bleed the system, this is actually the hardest part. It took me about two hours to do this entire process. Good luck, If you have any questions enmail me at dew101970@Yahoo.com. I will try to answer.
your power steering fluid return line, also known as your power steering low pressure line, may have a hair line crack in it and need to be replaced.

The filter is hose clamped into the low pressure return line to the pump. First, drain the power steering fluid, then cut the rubber hose line within an inch of the filter and install the new one.
remove pump with line then change and reistall
You need line wrenches to be able to break it loose without stripping the ends whatever the size I did not see the app you are working on
At the lowest hose point available, loosen a steering fluid line and allow to drain into a bucket. When the system has drained, tighten the line and fill the system with new fluid.
The most common power steering pump leaks are at the line connections or behind the pulley at the shaft. The line leaks can possibly be repaired, but the shaft seal leak could be better to change the pump.
Have you checked the power steering pressure line?
Usually the leaks are at the high pressure line or the return line of the power steering pump. Tighten all the lines at the pump.
Noise may be heard in a power steering line when the power steering fluid is low. Low power steering fluid may occur due to a leaking power steering pump in most cases. If the pump is not leaking, then the fluid needs to be added.
