BW4403 Transfer Case

The Zumbrota Drivetrain RTC4403F-1 is a remanufactured BW4403 transfer case specifically engineered for 1999-2001 Ford Explorer and Mercury Mountaineer models equipped with AWD. This transfer case features a single-speed design and employs a one-way sprag for driving the front output shaft, differentiating it from units that use a viscous coupler. Zumbrota Drivetrain ensures the quality and reliability of each unit through rigorous inspection processes throughout the remanufacturing cycle. The cases are cleaned using state-of-the-art hydro blasting and rinsing to restore them to an OEM finish. During the remanufacturing process, all common wear components, including seals and bearings, are replaced 100%. This ensures that the transfer case is ready to perform to high standards upon installation. The units are shipped in high-density plastic totes to minimize the risk of in-transit damage, arriving at your door ready for installation. Technical notes indicate this unit is associated with tag numbers XL24-EA and XL24-EB, Hollander number 412-00412, and other numbers such as UMT429-3. A refundable core charge of +$400 applies, which is returned upon receipt of your old, salvageable part for recycling or rebuilding.
