The Zumbrota Drivetrain RAA435-1885A is a remanufactured complete axle assembly, meticulously rebuilt to restore precision and reliability to your vehicle's drivetrain. Each assembly undergoes a comprehensive inspection to ensure straightness, absence of cracks, and minimal surface wear. Zumbrota's commitment to quality means all internal components, including the ring and pinions, internal gears, clutches, and carriers, are thoroughly inspected and tested. To guarantee peak performance and durability, every bearing, seal, crush sleeve, pinion nut, and shim is replaced with new parts. This axle assembly boasts an 8.8-inch ring gear with a 3.55 ratio and a semi-floating axle type. The remanufacturing process includes a unique hydro-blast rinse and sandblasting procedure, followed by a deep cleaning process that restores internal and external parts to an OEM finish. Zumbrota pays close attention to gear setup, establishing precise rolling torque using inch-pound measurements and setting the correct gear backlash to ensure optimal lubrication and quiet operation, contributing to the assembly's longevity. Key specifications include a semi-floating axle type, an included cover, and the absence of included fluid. This unit is designed for direct fitment on 1996-2001 Ford Explorer models (Eddie Bauer, Limited, XLT, and XLS trims for 1999) and 1997-2001 Mercury Mountaineer Base models. It's important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts, and is specifically for vehicles without Posi Traction.
