Help! Need 2003 Manual on Disco SE!

[Idlecarrots]

I need to get a repair manual on my 2003 Disco SE because I refuse to spend the high price of the Land Rover shop repair. It's very frustrating because I can't figure out the problems. The high pitched humming while driving, and the loud locking door locks when diving off from park. Not to mention the squeaking brakes and the valve cover gaskets. Anyone please help!
