What Is Pump Rub?

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. The pump housing has tabs that fit into spots in the rear housing to locate the pump housing and prevent it from spinning inside the case with the mainshaft. Over time, these pump tabs can wear on the rear housing and start to wear on the aluminum pump housing causing a small leak. Due to the location of the leak, many vehicles do not experience dripping while parked, but rather while driving, leaving it gone unnoticed. The transfer case on these vehicles do not have a low fluid indicator, which means that by the time the problem is noticed, it is usually too late.

From the factory, GM installed a spring steel clip in the housing to prevent this type of wear, but this has proved to break and become useless in these situations.

With the installation of this transfer case repair/upgrade kit, you can prevent this before it happens and avoid costly repair bills. You will also get a LIMITED LIFETIME WARRANTY against pump rub. If you have this kit installed and your case wears a hold in the new rear housing, we will buy you a new transfer case. This warranty will only apply to installations with a new rear housing.
