Differential Case – GM (23347682)

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.

This Differential Case is listed as part 23347682 (Differentials). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

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is genuine GM, and this Differential Case keeps the original engineering number, which matters once a number has been superseded more than once.
