Today I heard the onset of a very prominent whining noise in my 300TD that gets louder under load. Seems to come from the rear but not 100 percent certain. It gets VERY loud going up hills, accompanied by an ominous grinding sound under load while driving uphill. The whining varies in pitch that roughly matches engine/car speed. We made it home OK but I am really spooked and unwilling to drive it again without a consensus diagnosis from the network of experts out there. SWMBO thinks it's the differential - does this jive with the symptoms? Rear axle? Driveshaft? U joint bearing?? Gear in the transmission (although the shifting is smooth with no flaring or slipping). I should also add that all fluid levels are normal and the transmission fluid is red and clean, not burnt.
