Problem Details:

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 pump rub.

Our special replacement rear cases 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.
