Reman Axle Assy GM 10 Bolt 8.5-Inch 3.42 Open

The Zumbrota Drivetrain Reman Axle Assembly is a comprehensively rebuilt unit for the 1988 GM 1500 4WD model. This axle assembly is built around a GM 10 Bolt rear end, featuring an 8.5-inch ring gear and 28 spline axles. It is configured with a 3.42 gear ratio and an open differential, identified by ratio option GU6. The remanufacturing process at Zumbrota Drivetrain involves meticulous attention to detail. Housings are subjected to a state-of-the-art hydro blasting and rinsing process to restore them to an OEM finish, followed by thorough inspection for surface wear and cracks. Internally, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new components. Furthermore, every internal part, including ring and pinion gears, internal gears, clutches, and carriers, is inspected to guarantee performance and durability. The correct rolling torque is established using precise inch-pound measurements to ensure setup accuracy and longevity. The unit is built to order and has a lead time for shipping. A refundable core charge of $400 is applied, which is returned upon receipt of the old, salvageable part.
