Description

The Zumbrota Drivetrain Reman Axle Assy is a professionally rebuilt axle assembly designed for 1989-2000 GM Pickup and Suburban models. This unit is built to the highest quality standards, ensuring precision and reliability. It features a 9.5-inch ring gear, a 3.73 axle ratio, and a Posi limited-slip differential, making it suitable for applications requiring enhanced traction. The axle type is semi-float, with 8 lugs. During the remanufacturing process, all tubes are inspected and straightened to OEM specifications, and housings are tested for surface wear and cracks. Internals, including the ring and pinion, gears, clutch, and carrier, undergo a 100% inspection. Critical wear components such as bearings, seals, crush sleeves, pinion nuts, and shims are all replaced to ensure maximum service life. The housings are cleaned using a hydro blasting and rinsing process to restore them to an OEM finish. Additionally, correct rolling torque is precisely established using inch-pound measurements for optimal setup and longevity.
