Installation Notes and Tips

Verify the vehicle’s RPO code NR3 before ordering, since this housing is listed for vehicles without the single-speed, open-differential AWD transfer case configuration. Confirm the 42 mm inside diameter, 11 mm mounting hole diameter, and five-hole mounting pattern against the original part before installation. Because installation hardware and seals are not included, reuse or source the required related components as needed during service. Fits 2015-2020 Cadillac Escalade, front; fits 2012-2020 Chevrolet Tahoe, front; fits 2012-2020 GMC Yukon, front.
