Front Axle Assembly, Dana 44, 3.21 Ratio

The Zumbrota Drivetrain RAA434-116A is a meticulously remanufactured front axle assembly, specifically engineered for the 2007 Jeep Wrangler. This unit features the robust Dana 44 housing with an 8.5-inch ring gear and a 3.21 gear ratio, configured for Left Hand Drive operation. Zumbrota Drivetrain rebuilds these axle assemblies to exacting quality standards, ensuring precision and reliability. The process involves thorough inspection of all components, including the housing for straightness and cracks, and internal parts such as ring and pinions, gears, clutches, and carriers. All bearings and seals are replaced with new ones. The remanufacturing process includes ensuring optimal tooth contact patterns and correct rolling torque, using inch-pound measurements for precise setup and longevity. Proper gear backlash is set to guarantee adequate gear lubrication and quiet operation. The axle tubes are inspected to ensure they are straightened to OEM specifications. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning, to prepare all parts. This front axle assembly includes the main housing and its internal components. It does *not* include axles, ball joints, spindles, steering components, or brakes. Mounting hardware is also not included, and the unit does not come pre-filled with oil. A core charge is applicable and refundable upon the return of your old, salvageable part.
