What Does a Pump Rub Kit Do

Pump Rub refers to a gear pump failure in GM transfer cases from 1998-early 2007. The gear pump works by forcing oil to the planetary as well as the drive sprocket sleeve. The gear pump is driven by a shaft, so the housing of the pump must “float” in the rear housing of the transfer case.

What is Duramax pump rub?

Pump rub occurs when the four positioning tabs holding the pump in place wear over time. This causes the oil pump to come into contact with the housing itself. The result is a hole worn in the cover, causing fluid to leak and the probability of damaging the transfer case.

Can you bypass a transfer case?

No you cant really bypass the transfer case, it must be there for mechanical and electrical reasons such as the speed sensor on the back.
