Candidate cause (the documents say what to do)
Transfer case pump rub (hole worn through rear case half)
The magnesium case is softer than the aluminum pump, and pump movement in normal operation eventually wears a hole in the rear case half.
The factory spring steel anti-rattle clip does not protect the case in the long term.
What to do
- Fluid loss is hard to notice without going under the truck and removing the fill plug to check the level.
- Larger locating tabs prevent the pump from rubbing through the case as it moves.
What is needed
- Parts and materials
- Not stated
- Labor time
- Not stated
- Special tools
- Not stated

The magnesium case is softer than the aluminum pump, and pump movement in normal operation eventually wears a hole in the rear case half.
While both metals are soft, the magnesium is considerably softer than the aluminum and pump movement during normal operation will eventually wear a hole in the rear case half.

The factory spring steel anti-rattle clip does not protect the case in the long term.
A small spring steel anti-rattle clip is installed from the factory to mitigate the movement and wear, but the anti-rattle clip is not up to the task for long term case protection.
