From past experience with both 4X4 and 2X4 trucks involved in heavy towing the transfer case is the weak link.
I not completely familure with the transfer cases in CD's but in some trucks they use a chain and the chain stretches. Remember the transfer case is in the drive line all the time not just when in 4wd.
Good luck.
