What Is Pump Rub? Pump rub occurs in GM transfer cases (1998–2007) when the pump housing wears through the rear case, causing fluid leaks that go unnoticed until it’s too late. This kit prevents pump rub by replacing the factory housing with a stronger one and comes with a limited lifetime warranty.

Grinding Noise After Install: Check if the rear output bearing snap ring is fully seated.

Speed Sensor Correlation Code: Also caused by the rear output bearing snap ring not being seated properly.
