Description

The Zumbrota Drivetrain Reman Axle Assembly is a remanufactured differential designed for specific Ford F250 models from 1987 to 1989. This unit features a Posi-Traction (limited-slip differential) for enhanced traction and performance. It is equipped with a 3.73 gear ratio and a 10.25-inch ring gear, suitable for heavy-duty applications. This particular assembly is configured without ABS. During the remanufacturing process, Zumbrota Drivetrain ensures the highest quality standards. All axle tubes are inspected and straightened to meet OEM specifications, and housings are rigorously tested for surface wear and cracks. Internal components, including ring and pinion gears, internal gears, clutches, and carriers, undergo a 100% inspection. Critical wear items such as bearings, seals, crush sleeves, pinion nuts, and shims are all replaced with new parts. The housing is then cleaned using a hydro-blasting process to restore its original OEM finish. Precision setup is achieved through the establishment of correct rolling torque, ensuring longevity and reliable performance. This axle assembly is built to order and shipped when ready. It is important to confirm fitment for your specific vehicle. A refundable core charge applies, which is returned upon the receipt of your old, salvageable part.
