Richardb,
This is a great DIY!
So easy, even a caveman could do it!
IMHO, a great low cost preventative component that I will replace to avoid an inopportune failure of the AWD system.
I'm planning to continue having X-periences beyond my current 95K miles and things like these are an easy decision for me.
Buying this one right now and will change it at my convenience. Had I known about this when I did the xfer case, tranny and diff fluids I would have changed it then.

Does this DIY apply to the 2003 E53? "pre-facelift" vehicles?
This PN appears to be for the 2003 or pre-facelift vehicles:
