I have just recently purchased a 2001 BMW 740iL for a very good price but the only problem was it has a power steering fluid leak from either the inlet or outlet hose and the pump needs to be replaced. I can see everything pretty much and I have changed alternators and pumps on other types of vehicles but not BMW and I am trying to save money. What is the level of difficulty on performing this and and what is a good resource for performing this repair?
The only way to do that is to buy factory manual, the reason you cannot see anything, it is because you will have to pull radiator, to even look at the steering pump, and of course get on your back.

Thanks Dr. Loot,
I have already ordered the Bentley manual. I have another question for you though. To verify the cause is the pump I turned the car on and looked in the fuel reservoir for fluid movement and there was no movement. Does that mean it should be replaced?
I also have been unable to locate the point of the leak to veriy it is the hoses, is that because the pump isn't working properly? My ATf fluid has not changed.

You see no movement in the power steering reservoir that does not mean it's not working, the manual that you are ordering will give you a step by step procedure on how to diagnose your power steering problems, but if I were you I would remove the Belly pan, that is the cover underneath the engine and go to your local car wash be very careful and clean around the power steering pump and the hoses, to assist you in trying to find a leek. If you have any more questions during your operation don't hesitate to call on me.
