Differential Case – GM (14038087)

Differential Case is a containment or structural component matched to a specific casting and bolt pattern. Parts that look interchangeable often differ in offset or internal volume.

Replace the Differential Case when the casting is cracked at a mounting point, when a mating flange is no longer flat, or when the original has corroded through. Check the surface it seals against before fitting a replacement.

Ordering reference for the Differential Case is part number 14038087, categorised under Differentials. Match that number against the component you are removing before you order.

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is genuine GM, and this Differential Case keeps the original engineering number, which matters once a number has been superseded more than once.
