This is a also a good time to move the condensation water outlet hose so that it does NOT drip water on the drive shaft just before it enters the transfer box (mentioned in another E53 thread). Loosen the rubber mounting bracket with a 10mm socket, adjust the hose so that it drains directly to the ground and tighten up again. (May wish to do this next time you drain the engine oil?)

Thanks for tip oon the outlet hose. Changed oil on my 2005 4.4 and did the GT1 oil change procedure.
My transfer case is making a whining noise at all speeds but the oil change didn't make a difference although the drained oil was very dirty at 92k miles. There were no metal shavings though as determined by finger feel and running magnet through the drained oil.
