Front Differential Case – GM (84756918)

Front Differential Case holds, shields or mounts other components in the assembly. Bolt spacing and depth are what decide fitment, and neither is visible without measuring.

Replace the Differential Case when the bolt holes have elongated, when the gasket surface is pitted, or when the part has distorted from heat. A warped flange leaks with any gasket.

The Differential Case in this listing carries part number 84756918 and sits in the Differentials category. The number stamped on the original part is the only reliable cross-reference.

The stock here is genuine GM, and this Differential Case keeps the original engineering number, which matters once a number has been superseded more than once.

This is the front unit in the assembly; confirm the location on your vehicle before ordering.
