2.73 Posi Traction Differential Carrier Assembly

The Zumbrota Drivetrain RAA435-1814B-P is a remanufactured axle assembly designed for the 1994-1998 Ford Mustang with a 7.5-inch Ford ring gear. This assembly includes a Posi Traction limited-slip differential and a 2.73 gear ratio, specifically built for models with ABS. It is important to note that this unit does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately. Zumbrota Drivetrain rebuilds these axle assemblies to stringent quality standards, ensuring precision and reliability. The process involves a thorough inspection of all internal components, including the ring and pinion, internal gears, clutches, and carriers, for wear and integrity. To guarantee longevity and optimal performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. Gears are meticulously inspected for proper tooth contact patterns and set to the correct rolling torque using inch-pound measurements. Backlash is precisely adjusted to ensure adequate gear lubrication and quiet operation, while axle tubes are inspected to confirm they meet OEM specifications for straightness. Zumbrota employs an exclusive cleaning process, utilizing hydro-blasting and sandblasting for both internal and external parts, followed by a proprietary shot-peened deep cleaning. This advanced remanufacturing method sets a high standard for axle assembly quality.
