stolen from ^^^

Dodge used variations of this Hydrolok system in all the Gen 3 Vipers. In talking with Devon from Unitrax (http://www.gounitrax.com), he told me that one of the problems with this system was the metal used in creating the differential’s internal gears or spider gears. This metal was not the best quality for the high stresses that are subjected to the internal parts and thus the metal begins to break down and fail. Dodge attempted to correct this in later versions, however, parts were still prone to failure. Gen 4 Vipers got a whole new differential called the "Visco lok" which cured the poor metal problem. Since Dana is in the business, he has seen plenty of Viper differentials in his time and shops all over the country send him Viper differentials as well as diffs for other makes and models to be rebuilt.
