I'm hearing a grinding noise above 35MPH when the 4wd is selected and the gas pedal is pressed. When it's coasting, under 35MPH or in 2wd there is no noise. Does anyone know what it could be as my 2005 Pathfinder is out of factory warranty. Thanks.

I tried it again and it's more of a loud humming noise over 35MPH, 4wd engaged and giving it alittle gas. Anyone know what is this humming noise? Thanks!

If you have under 60K miles, you are still under the powertrain warranty!
