Differential Case – GM (84011439)

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 84011439 and sits in the Differentials category. The number stamped on the original part is the only reliable cross-reference.

Genuine GM supplied for this Differential Case, with the engineering number unchanged from the factory reference stamped on the original.
