The oil pump pushes oil against the rear case half causing pin-holes to develop in the soft thin magnesium shell.
The oil evaporates out of the transfer case. This happens so gradually that you probably don't realize it until
there has been sufficient damage done to the internal mechanisms. We call this the oil
Our special replacement shell half for the rear of these transfer cases fixes that issue. They are made of
heavy grade aluminum, not thin magnesium. In addition, these replacement upgrades correct a snap
ring groove problem and require no adapter plate. You will appreciate the durability and craftsmanship built
into these parts.
