thanks for your response Tmenna -- This is making me think that your vehicle problem was something other then the transfercase. Possibly mine could be the same thing. I changed the right front wheel bearing a month ago becouse of a loud noise coming from that area. After I changed the bearing the noise was gone and I was hoping at the time that wheel sensor was bad and was causing my transfer case problems. But it did not change anything other then the noise went away. Could my left side wheel bearing be bad and sensor not working and me not even notice it -- and if that is a yes -- would that have something to do with my transfercase being in 4x4?
