Differential Case Assembly – Mopar (68643831AA)

Differential Case Assembly 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 68643831AA (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 Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.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genuine MOPAR, and this Differential Case keeps the original engineering number, which matters once a number has been superseded more than once.

This is sold as an assembly; if only one component has failed, confirm whether the single part is available separately.
