My steering was starting to feel heavy and the pump was starting to make an audible noise. I purchased a used unit off ebay for 40 bucks and bought a rebuild kit at the same time. You dont need to go into full service mode like me, but to goto full service mode, is only two coolant lines and to drain/refill. Not a big deal by any means.
Stick an oil pan under the power steering area, crack your power steering lines loose, a 22mm for the line going to the rack and 24 for the return. Just crack them until they are bleeding, open your PS reservoir. Check that the fluid is hitting the pan, it'll trickle off the AC compressor. There is a drain plug on the bottom of the pump, but you have to get on your back to reach that. pffffttttt....
Remove your fan clutch with a spanner and large crescent wrench, reverse thread. IE hammer the crescent wrench clock wise. Grab a 13mm deep socket and breaker bar, release the tension on the serpentine belt(aim at 3o'clock and pull up) and remove the belt.
Use the belt to wrap around the power steering pump pulley and hold it with your left hand, and grab a 6mm allen key in the right while pointing to 3o'clock and pull up hard with both. Make sure you clean the bolts out real good, I spent a solid 20 minutes cleaning them out. And took alot of force to crack these loose.
