replacing steering gear box 740IL 1999

I've pretty much done all the work on my Bimmer, my 740Il has a leakage in the power steering gear box and the steering column is hard to turn. I've already had my power steering pump check out and its working fine/nothing wrong with it.

I'm having problem with disconnecting the power steering gear box from the steering column. Does anyone have some information or diagram instruction how to removed and installed a power steering gear box on an 740IL 1999 BMW.


Need some assistance:dunno

Thank you,
