Dana 70 Rear Axle Assembly 4.10 Ratio

The Zumbrota Drivetrain RAA435-116C is a remanufactured complete axle assembly designed for the Dana 70 axle platform. This unit features a 4.10 gear ratio and a 10.5-inch ring gear, suitable for single rear wheel (SRW) and full-float axle configurations. Zumbrota Drivetrain meticulously rebuilds each axle assembly to stringent quality standards. The process includes thorough inspection of all internal components such as ring and pinions, internal gears, clutches, and carriers. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced to ensure optimal performance and longevity. The remanufacturing process involves more than just part replacement. Gears are inspected for precise tooth contact patterns and set to correct rolling torque using inch-pound measurements. Axle tubes are verified for OEM straightness, and housings undergo a specialized hydro-blast and sandblasting procedure, followed by a proprietary deep cleaning process. This comprehensive approach ensures the axle assembly meets high standards of reliability and quiet operation. This specific assembly is configured for the 2005-2007 Ford E-350 SRW. It is important to note that this axle assembly does not include hubs, brakes, backing plates, or axle shafts. It is a Posi LSD differential type.
