The same "logic" that was used on the rear differential cover was also used on the front differential cover - no drain plug. The transfer case, however, has both drain and fill plugs. (Brilliant!) I'm putting one 1/2" NPT magnetic plug in the transfer case drain location, and another in the front differential fill location on the assumption that when the gears turn the gear oil will come in contact with the plug. The company advises to put magnetic plugs in both the drain and fill locations if you have them.
