2002 Mercury Mountaineer AWD whining from the back

Asked by Sep 04, 2016 at 10:47 AM about the 2002 Mercury Mountaineer 4 Dr STD AWD SUV

Question type: Maintenance & Repair

Hello...My Mountaineer drives fine and had front driver side hub bearing
changed recently...The hub beating did make a difference with an issue I did
not realize was there since I brought it in for this whining, grinding sound from
the back....Brought it back to mechanic and they are not sure if it is a drive
shsft, differential or other issue....Back brakes just passed inspection fine
although the grinding type noise is heard when breaking and whining noise is
heard while moving at any speed...I do not notice grinding or whining while
parked and accelerating....Thank you for any feedback you can provide....

As the whine goes away during acceleration that really sounds like a differential, as this an AWD unit it could the front or both of them, my old Mountaineer the front went out first and it made a whine that telegraphed through the whole rig, I removed the front driveline and the whine stopped so I knew that I had to overhaul the front differential, so if they have traced to to a noise in the rear the chances are high that rear differential needs work. As far as the brake grinding noise, if the brake pads are full metallic or ceramic they can make a grinding noise when they wear to a certain spot that might have a slightly harder mix on the pad lining itself, sometimes a good cleaning with some sandpaper or emery cloth will cure the problem.
