Remanufactured Axle Assembly for Dana 44

The Zumbrota Drivetrain RAA434-1547C is a remanufactured axle assembly designed for the Dana 44 differential. This assembly is built to exacting standards, ensuring precision and reliability. The remanufacturing process involves a thorough inspection of the housing for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are inspected and tested. As part of the rebuild, all bearings and seals are replaced to guarantee optimal performance and longevity. Zumbrota Drivetrain utilizes a proprietary cleaning process that includes hydro-blasting and sandblasting, followed by a deep cleaning treatment, to restore housings to OEM specifications. Gears are meticulously inspected for proper contact patterns and set to the correct rolling torque using inch-pound measurements. Gear backlash is precisely adjusted to ensure adequate lubrication and quiet operation. This specific axle assembly features a 3.92 gear ratio and an 8.5-inch ring gear size with a vacuum disconnect. It is important to note that this assembly includes the main housing and internal components only; it does not include axles, ball joints, spindles, steering components, or brakes.
