Case Differential – Ford (8u9z4205a)

Case Differential 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 Case Differential 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 Case Differential is listed as part 8u9z4205a (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 Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.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is genuine FORD, and this Case Differential keeps the original engineering number, which matters once a number has been superseded more than once.
