The housing is constructed from aluminum alloy and includes the internal service components listed in the product data, along with seals to support a leak-free repair.

The Dorman 917-561 is also a practical choice for 2002-2007 Cadillac Escalade, rear, and other listed GM 4x4 platforms.

Common Problems This Part Can Address

Transfer case fluid leaking from a damaged housing

Installation Notes and Tips

Verify the transfer case RPO code and vehicle configuration before ordering, especially on GM trucks and SUVs with NP8 push-button shift or NP2 manual shift transfer cases. Confirm rear-position application and compare the original housing to the replacement before installation. Clean all mating surfaces thoroughly and inspect related transfer case components for wear or contamination during service.

Quality Assurance

Dorman manufactures this housing as an OE-style replacement part for restoring proper transfer case fit and sealing performance. The included seals are intended to support a leak-resistant installation when the housing is installed correctly and the mating components are in serviceable condition.
