I'm experiencing a sort of grinding noise when coasting, it seems to be coming from the mid to rear end of the truck, very hard to pin point. I just finished replacing front hub assemblies, from sway bar end links, both front axles, and brand new goodyear fortera rubber all the way around. The best way I can describe the noise is as if there were a rusty spot on one of the rotors and as the wheel turns the brake pad scrapes that rusted spot on the rotor, which is not the case.
I'm considering doing the brown wire mod on it to rule out the transfer case. Prior to this I did drive the truck on two different occasions before I had the rear tires put on, so I was thinking that it might be difference in tire tread depth and perhaps the truck was partially engaging the transfercase. BUT since I have put new tires on the rear to match the front, I'm guessing this isn't the problem. (note: tires are exactly the same, and the front tires only have about 15 or less miles than the rear tires have on them). Also, it seems to only do it when coasting. Perhaps a bad rear bearing? I don't really know much about the history of the truck prior to me owning it, so I'm not sure whether the rear bearings have ever been replaced. By the looks of the front hub assemblies I'm guessing none of them have.
Also, I might add that the rear diff does wine pretty loud. Not sure if it could be related or not.
