I took the D to the drop shop yesterday, for the "final" modifications, and we noticed that there's some chatter coming from the transfer case, when idling in park. I think this slowly developed about three months ago, but it was so gradual & subtle, I had to stick my head under the truck to really notice it.

I've searched the threads, but I don't really find an exact match. The T-case has had regular PM, & exhibits no other obvious symptoms.

Any ideas? TIA!

In park, there's nothing moving inside the transfer case, I think the noise may be carrying from somewhere else.

That's what I was thinking, too.

The t/case is chain driven between the input and output to the front driveshaft. The chain could have stretched enough to be rattling in the case. Not an uncommon happening. Usually not noticed until the case comes apart, either for maintenance or because it blew out.

That makes sense! I'm going in in a couple of weeks for the install of the new tranny pan & rear diff cover. I'll have it looked at then?Thanks, Mike!
