Transfer Case Adapter – GM (84263509)

Transfer Case Adapter is a formed or cast component that surrounds or supports part of the powertrain. Corrosion and cracking at mounting points are the usual reasons for replacement.

Replace the Transfer Case Adapter when you find a crack that weeps under pressure, or when the mounting ears have failed. Welding a casting rarely restores the original alignment.

Reference number for the Transfer Case Adapter: 84263509. It is filed under Transfer Cases, and it is the number that has to match the part coming off the vehicle.

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