203 T-case rattle ?

History: I have a 203 T-case in my '78 Blazer. It has the lock-out kit in it & locking hubs. I put this rebuilt case in about 7 yrs ago. For a while now I've heard a metalic rattle, or pinging, coming from the T-case area. Usually when the drive train is under load. If I accelerate, it goes away. It seems to be worse when it's hot, 100 degrees + (typical Arizona day) but it's quiet in the morning.
Question: Does the chain move when in 2 wheel drive ? I talked to a few off-road shops and they don't seem to know for sure. Just thought somebody might be familiar with these symptoms. Any ideas ?
