August 17, 20102002 expedition 4 wheel drive. Just got hit with an estimate to fix this humming noise coming from I dont know where. The truck drives fine besides the noise. Mechanic said it was the transfer case and differentials that were bad and it would cost 2k to fix. Thats insane! Is there any way of knowing if this is the actual problem. Need help please!!!

September 21, 2010WOW, sounds like someone was taking a shot in the dark, LOL. What I did on my Bronco was have someone drive it for you, then drive a different vehicle next to it to see if you can pinpoint the area you`re hearing it from.
