nj...I'll fill ya in on how my transfer case sounds. If I take off from a standstill under hard acceleration I get an EXTREMELY loud thump...sometimes a few thuds in a row. If I take off the front driveshaft the noise is gone. I have changed the driveshaft and still get the thump. I would say if you are getting a clicking try the driveshaft first. Mine's definitely the case (I hope

) and I liken the noise to a bike with a loose chain. Remember when you would pedal really hard and the chain would slip? Magnify that by 100)
