Additionally, axle tubes are inspected to ensure they meet OEM standards for straightness.\n\nZumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process on both internal and external parts. This advanced cleaning method sets a high standard for axle assembly remanufacturing, ensuring a like-new finish and integrity.\n\nThis specific assembly is designed for 1999-2004 Jeep Grand Cherokee models equipped with Quadra-Drive.
