The pressure from the oil pump against the rear case half causes pin holes to develope, then oil leaks out of the transfer case. It happens so slowly that you do not even realize it until you are out of business. This is called the oil pump rub.

In addition, these replacement upgrades correct a snap ring groove problem and require no adapter plate. You will appreciate the durability and craftsmanship High Gear has built into these parts.
