I have a garden hose section and use it as a stethoscope to help track down the noise source.
Sometimes, can tape or wire free end to a component such as the tranny at front pump area and torq. converter; then back at Xfer case, etc.
Beware of hot engine, belts, pulleys & fan, as applicable

This may be caused by transmission fluid leaking from the transmission into the transfer case through the transfer case input seal. Replace the transfer case input seal..." Source: by Ford
ISSUE: The transmission may have low fluid level and/or may have either a shift concern and/or an engagement concern. This may be caused by transmission fluid leaking from the transmission into the transfer case through the transfer case input seal.
ACTION: Replace the transfer case input seal. The new seal should reduce the possibility of fluid leaking from the transmission into the transfer case. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
1. Check the transmission fluid level. It the transmission fluid level is low and there are no visible signs of a leak, check the transfer case fluid level. The level of fluid in the transfer case should be just below the fill plug hole.
2. If the transfer case fluid level is overfull and the transmission fluid is not burnt, remove the transfer case from the vehicle following the procedure outlined in the appropriate model/year Service Manual.
3. Remove the transfer case input seal. Clean the seal bore in the transfer case.
4. Install a new Transfer Case Input Seal (F77Z-7B215-AA)
5. If the transmission fluid is burnt, repair the transmission as required and then replace the transfer case seal as outlined in Step 3.
