New guy needs help with steering

[GLS_Jeff]

Hey everyone. Had my baby for two weeks now. I have a 2000 GLS 3400. Lost my power steering and noticed it was leaking out the bottom back of the engine. Replaced the High Pressure hose and was positive that was it and its not F_ _ _ ME! Now i think it's the leaking from the rack/pinion. I found a remanufactured one on ebay for $95 shipped but im wondering if this is something I can even do myself. The hose took like 2 hours to change cause I had a whole 3 inches of space to work in. Is this like a mission impossible job? Also my pump is now vibrating and making a whinning sound even when it has fluid in it for the whole minute it lasts before it all leaks out. Did I also fry the pump? I drove the car home about 10 miles after the power steering went out. Thanks guys
