Transfer Case – GM (86798719)

Transfer 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 Transfer 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 Transfer Case is listed as part 86798719 (Transfer Cases). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

This is GM dealer-sourced stock rather than an equivalent, so the number on the Transfer Case traces straight back to the manufacturer.
