Your very welcome. If that is the case it could be a mount for the transfer case, did not know it was AWD, or a busing and still could be a universal joint. If it is internal, you would probably have some shifting problems accopyaning the noise such as hard shifts or slipping between shifts or when in gear. The transfer case behaves differently though. Interanl damage to it would cause a loss of power to the front or rear axle and then the pop might be it re-engaging the axle. You might still be able to feel if there is a change in the way it handles or drives and the one axle that gets let loose might spin a wheel. However, if it were this severe of an internal issue, the van would have some sort of problem driving or change in the way it performas and I would expect it to fail completely very soon.
Otherwise I still think it is a mount, bushing or u-joint.
