Overview

The Zumbrota Drivetrain RAA435-2098A-P is a remanufactured axle assembly featuring a Posi Limited Slip Differential with a 3.08 gear ratio and a 7.5-inch ring gear. It is designed for GM 7.5-inch applications from 1998-2003, including S10, S15, and GMC Sonoma models with 4x4.

This axle assembly undergoes a rigorous remanufacturing process, including a 100% inspection of all internal components such as ring and pinions, internal gears, clutches, and carriers. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are inspected for optimal tooth contact patterns and correct rolling torque, with backlash set for proper lubrication and quiet operation. Axle tubes are straightened to OEM specifications, and housings are tested for wear and cracks. Zumbrota utilizes a hydro-blast rinse and sandblasting procedure, followed by deep cleaning, to restore internal and external parts to an OEM finish.

The Zumbrota Drivetrain RAA435-2098A-P is a remanufactured axle assembly built to high standards of precision and reliability for GM 7.5-inch applications from 1998 to 2003, including the Chevrolet S10, S15, and GMC Sonoma 4x4 models. This unit features a Posi Limited Slip Differential with a 3.08 gear ratio and a 7.5-inch ring gear. The assembly includes the axle cover but does not include fluid. During the remanufacturing process, each axle assembly is thoroughly inspected for straightness, cracks, and surface wear. All internal components, including the ring and pinions, internal gears, clutches, and carriers, undergo a 100% inspection. Zumbrota replaces all bearings, seals, crush sleeves, pinion nuts, and shims. Gears are meticulously inspected for optimal tooth contact patterns and correct rolling torque using inch-pound measurements to ensure precise setup and longevity. Proper gear backlash is precisely set to guarantee adequate gear lubrication and quiet operation. Axle tubes are inspected and straightened to meet OEM specifications. Housings are tested for surface wear and cracks. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on all parts, followed by a proprietary shot-enticed deep cleaning process. This comprehensive cleaning method restores cases to their original OEM finish, setting a high standard for axle assembly remanufacturing.
