Reman Front Axle Assembly, 3.91 Ratio

The Zumbrota Drivetrain Reman Axle Assembly is a meticulously rebuilt front axle assembly designed for the 2004-2009 Cadillac SRX, featuring a 3.91 gear ratio and a Getrag 7.6-inch ring gear for IFS applications. This unit is constructed to the highest quality standards, ensuring precision and reliability. Each axle assembly undergoes a rigorous inspection process. This includes checking for straightness, surface wear, and cracks in the housing. Internally, all components—including the ring and pinions, internal gears, clutches, and carriers—are fully inspected and tested. Zumbrota replaces all bearings, seals, crush sleeves, pinion nuts, and shims to ensure optimal performance and longevity. The gears are set to precise backlash specifications for proper lubrication and quiet operation, with rolling torque established using inch-pound measurements. Zumbrota employs an exclusive cleaning procedure that involves hydro-blasting and sandblasting for both internal and external parts, followed by a proprietary shot-peening deep cleaning process. This extensive remanufacturing process aims to restore the axle assembly to OEM standards. Units are shipped in high-density plastic totes to prevent in-transit damage. The product is backed by a 2-year limited warranty.
