Remanufactured Axle Assembly 3.42 Ratio

The Zumbrota Drivetrain RAA435-2212A is a remanufactured axle assembly engineered for 2003-2005 GMC Astro and Safari vehicles equipped with the GM 7.5" differential and a 3.42 gear ratio. Each assembly is meticulously rebuilt to restore performance and reliability. During the remanufacturing process, all tubes are inspected and straightened to OEM specifications, and housings are checked for surface wear and cracks. A comprehensive 100% inspection is performed on all internal components, including the ring and pinion, internal gears, clutches, and carriers. To ensure longevity and proper setup, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The housings are also cleaned using a hydro-blasting process to achieve an OEM finish, and correct rolling torque is established through precision measurements. This axle assembly is built to order and ships when ready, with options for expedited shipping available at checkout. Zumbrota Drivetrain offers a core charge of $400, which is refundable upon return of the old, salvageable part.
