Alright, go another issue I need some assistance with. I recently put on a 6" suspension lift running 35" Nitto Mud Grapplers. When I had the rims and tires off and everything all disconnected, I checked my pads and rotors (they looked fine, minimal wear for front pads and rotors). I had replaced my hubs about 2 months before doing all of this (so about 6 months ago.) About a month ago, while driving into work I was going about 10 or 15 and heard a sound (metal to metal...like a rubbing sound) but not a constant one, like it would come in for a second while the tires were in a certain position in their revolution. So I think nothing to serious of it, and keep driving it (it's my daily driver/weekend toy). Now I am up in Connecticut, and had the truck shipped up here via an open-style car hauler. I get the truck delivered to my door, pay the guy, and he is gone. I test drive my truck and the sound that I described earlier (metal to metal...rubbing sound) that WAS subtle, is now EXTREMELY loud. I haven't jacked it up to check the hubs/bearings, but any ideas on what it could be? The only troubleshooting I've done is: 1) Driver window down, passenger window up, 10-15 MPH = sound is LOUD. 2) Driver window up, passenger window down, 10-15 MPH = sound not so loud.
