Most likely a tight universal joint. If you can hear it while the transfer case is in neutral and you increase engine speed, suspect a bearing in the transfer case. If you jack up the rear wheels off the ground, then run it in 2wd and hear the noise, suspect the u-joints although there are other bearings supporting the output shaft in the transfer case too.
