Crown Automotive Standard Differential for Case Assembly 4856357AS Durable Casting Services

For automotive repair specialists and Jeep owners, the integrity of the drivetrain is non-negotiable. The Crown Automotive Standard Differential Case, engineered for assembly number 4856357AS, represents a commitment to durability and precise performance. This product is manufactured as a direct OEM replacement, ensuring reliable operation and restored functionality for critical differential systems, particularly in demanding 4x4 applications.

Premium Material for Enhanced Durability

This differential case is produced using high-strength cast iron or ductile iron, materials chosen for their exceptional mechanical properties. The iron alloy provides superior tensile strength and outstanding resistance to wear and impact forces, which are paramount within a differential assembly handling significant torque from the drivetrain. Its excellent vibration-damping characteristics contribute to smoother power delivery and reduced gear noise. The metallurgical consistency of the casting ensures long-term reliability, resisting the stresses of on- and off-road use.

Precision-Controlled Production and Machining

The manufacturing of this differential case employs advanced sand casting techniques to create a complex, near-net-shape component with a dense and homogeneous internal structure. This foundational process is followed by precision CNC machining on critical surfaces. Operations including boring, milling, and drilling are performed to achieve exact OEM tolerances for the bearing journals, bolt holes, and gear mounting surfaces. This guarantees perfect alignment with the ring gear and a seamless fit within the axle housing, ensuring optimal gear mesh and long-term durability.

Direct Application for Reliable Performance

The Crown Differential Case for assembly 4856357AS is designed as a direct replacement for damaged or worn original components in specific Jeep rear axle assemblies. It serves as the core structure that houses the spider gears, allowing the wheels to rotate at different speeds during turns. A precise and robust differential case is essential for preventing binding, reducing abnormal tire wear, and ensuring proper power distribution. This product is the trusted solution for professional technicians and enthusiasts performing repairs, rebuilds, or restorations, restoring the vehicle's drivetrain integrity and off-road capability.
