Dana 44 Front Axle Assembly 3.90 Ratio

The Zumbrota Drivetrain RAA434-1908D is a remanufactured Dana 44 front axle assembly meticulously rebuilt for the 1999 Chrysler Ram 1500 equipped with a 3.90 gear ratio and 4-wheel ABS. Zumbrota Drivetrain ensures the highest quality standards by subjecting each axle assembly to rigorous inspection processes. This includes checking all tubes for straightness and ensuring housings are tested for surface wear and cracks. Internally, 100% of components, such as ring and pinions, gears, clutches, and carriers, undergo complete inspection and testing. To guarantee optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gear setup is precisely calibrated for correct tooth contact patterns, rolling torque, and backlash, ensuring proper gear lubrication and quiet operation. Zumbrota employs an exclusive cleaning procedure that includes hydro-blast rinsing and sandblasting for both internal and external parts, followed by a proprietary shot-enticed deep cleaning. This advanced process restores cases to OEM finish and sets the standard for axle assembly remanufacturing, ensuring reliability and durability for your vehicle's drivetrain.
