Dynatrac-built Dana 44s grace both ends of the ZJ. This one is filled with 4.56 gears and an Eaton ELocker. ELockers were used in both front and rear differentials. Tom notes, "When things get tough on the trail, it's a simple push of a button to lock either differential. An ELocker in the frontend reduces steering effort when four-wheeling because the ELocker can be unlocked during hard cornering."
