TRansfer Case Making Noise But Not Typical Cluck or Grinding

[summerblues]

My BMW X5 2003 3.0 81K

driven gently! (that hasn't helped as far as overall reliability,
wish I had my old beat up Jeep)

All right so I feel like an executive in my Beamer!

noise is coming from transfer case or with a few inches of there,

sounds like if the brake pads were touching metal

no grinding, no tac tac tac

oil is full.

I probably have the earlier version on transfer case NV something

only happens during acceleration !

starts at 5 mph and up to 30-40 mph,
sometimes loud sometimes much softer

can this be a stretched chain !

Its going to be a DIY project since I cant a$$$$$$$=ford
the price tag, I will even rebuild the thing if I have to,

Had the same issue with my old 2004 X5 at 67k miles. Took into dealer for proper diagnosis. They ended up replacing it under their "goodwill" policy.

Before you sink in some real dough, try taking it to the dealer and see if they will replace it under their goodwill program.

Does this noise exist only after 30 min of driving?? Because im getting the same noise ( ifififififif) after driving the x. I thought that it is a seized caliper
