What do I do with the OEM anti rattle clip when installing this upgrade?

Discard the factory clip during installation of the MA Transfer Case Pump Upgrade kit. It's been designed and precision machined to work with the clip removed.

What other parts will I need to install this upgrade and repair kit?

MA tried to make the kit all-inclusive for an upgrade and repair installation after pump rub failure has occurred without including internal parts (like bearings, shafts, planetary gears, etc...) that may not necessarily be required. Unfortunately, there is no real way to know the extent of the damage inside the case until it is completely disassembled. In many instances, as long as the case has not run out of fluid, it can be repaired with the new rear housing and components included in this kit to prevent pump rub from ever happening again. Be sure to refill the transfer case with the MA Performance Transfer Case Fluid included in this kit for excellent lubrication and performance and replace your original drain and fill plugs with the MA Magnetic Drain Plug kit also included with this kit as an additional layer of protection to catch metal debris from the fluid circulating inside the transfer case as well as replacing the factory plugs which are often rounded off or damaged.

I hear a grinding noise at low speed after installing the kit. What could that be?

A low speed grinding noise is most commonly caused by the rear output bearing snap ring not being fully seated causing the bearing to move out of proper alignment. Verify that the snap ring is fully engaged and properly seated in the rear housing and the locating groove in the bearing.

What would cause a speed sensor correlation code after installing this upgrade?

A speed sensor correlation code is often accompanied by a low speed grinding noise and is frequently caused by the rear output bearing snap ring not being fully seated causing the bearing to move out of proper alignment. Verify that the snap ring it fully engaged and properly seated in the rear housing and the locating groove in the bearing.
