Transfer case
I notice a very slight humming noise whenever I let off the throttle between 48-35 mph.Otherwise no noise at any other speed or under acceleration.Could this be a problem with the transfer case.I have 112,00 mi & have changed all fluids except transfer case.

Welcome! Please post a photo of the GLK.
Possible transfer case. Also:
- propshafts
- center propshaft support
- transmission mount
- halfshafts
- wheel bearings
- wheel/tire
Need more diagnostic testing. Closed throttle/no torque is an interesting phenomenon. Try coasting from 65mph down through 35mph with no throttle. What sounds are produced?
