3.55 Posi Limited Slip Differential

The Zumbrota Drivetrain RAA435-140B-P is a remanufactured axle assembly designed for Chrysler 8.25-inch differentials, specifically for 2007-2010 Jeep Liberty models with a 3.55 ratio and Posi Traction (Limited Slip Differential). Each axle assembly is rebuilt to stringent quality standards. Zumbrota Drivetrain performs comprehensive inspections on all internal components, including ring and pinions, clutches, and carriers, ensuring their integrity. All bearings and seals are replaced as part of the remanufacturing process. The gears are meticulously inspected for optimal tooth contact patterns and set to precise rolling torque and backlash specifications, which are crucial for proper gear lubrication, quiet operation, and longevity. In addition to internal component checks, the axle tubes themselves are inspected to confirm they meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process, which sets a high standard for the remanufacturing of axle assemblies. This specific assembly is for the Chrysler 8.25-inch ring gear and includes the housing cover.
