My 96 is makeing a lot of noise from what sounds like the trany. or the transfer case. The auto trany and transfer case has 211000 stock miles. Service has been done regular. The noise sounds like a bearing. I can hear it in all gears, but its the loudest in 3rd. The noise goes away when i put it in neutral, (at any speed). It doesnt make any dif under a load or coasting. I lifted the back of the truck and got under it to listen. I used a bar to hold to my ear and tryed to pinpoint where the noise is comeing from. Seems like the trany makes a little more noise than the case, but I dont want to go have a trany put in and then find out its the case! Im working on the road, so im not at my home where all my tools are. Ill have to have all the work done for me. Any one with an idea on how to figure which one is going bad, would surely help.
