On my way home from my last trip out to the desert I had this weird binding/ clunking noise and a tire chirp coming from somewhere in my drive-train. Saturday, I drove it around town a little after I replaced the steering rack and only noticed it when making turns, so I thought it might be my spider gears in the rear end. But last night I was moving the truck from the street to the garage and I noticed the 4wd lights flashing. I verified that I wasn't in 4wd or AWD. I drove around the block and the lights stopped flashing after a little bit of driving (Normally it engages or disengages really quickly). As I was pulling into the garage I heard the clunk and a tire chirp again, so I back up a couple times and was able to make it happen again. It almost felt as if 4wd engaged and chirped the tires, but it was hard to really tell where it came from (Whether it was the rear diff or t-case).
One concern I had that makes me think it might be the transfer case is that I was driving around in the desert in AWD mode most of the weekend. I'm wondering if that caused any sort of issue with how hard I was driving in that mode. Does it make any difference whether the center diff lock is engaged?
I was searching for some diagrams on the transfer case to get some ideas on failures and found a picture and PDF that shows some pretty good and detailed information on how the AWD works on the multimode transfer cases. The PDF is attached.
