whining

Hey everyone, I just bought a 2007 Ford Explorer XLT, 4.0L V6, 4x4. When I purchased it a few days ago it test drove just fine other than a humming noise which the owner told me was due to a bad wheel bearing. 2 days ago I put a new wheel bearing and hub assembly in on the passenger side and...

I have done a few searches, but I think I need a little bit better of an explanation than I've found. Here are my symptoms: 1994 Explorer 4x4 (w/manual hubs) When I'm on the highway, I get a loud "whining/whurring" noise from the driveline. I can't tell if it's the rear diff or the...
