Ductile Iron Internal Gear Differential for Case Premium Casting Services Product

Restore the performance and reliability of your classic Jeep with the CroCrown Automotive 44590 Standard Differential Case. Engineered as a direct OEM replacement for the Dana 35 rear axle found in 1987-2000 Jeep Wrangler (YJ, TJ) and Cherokee (XJ) models, this differential case provides a cost-effective and durable solution for repair shops and DIY enthusiasts. It delivers the precise fit and robust construction required to ensure proper gear alignment and long-term drivetrain integrity for both on-road and light off-road use.

Material and Durability Specifications
The CroCrown 44590 is manufactured from high-grade gray iron, a material chosen for its excellent castability, strength, and superior vibration-damping characteristics. This specific material composition ensures the case can withstand the operational stresses and torque loads generated by the vehicle's drivetrain. The casting undergoes a controlled manufacturing process to achieve a consistent microstructure, providing reliable performance and resistance to wear. This makes it a dependable component for restoring the factory-spec operation of the open differential in the Dana 35 axle.

Precision Engineering and Manufacturing Process
This differential case is produced using precision sand casting techniques, which allow for the accurate reproduction of the OEM geometry, including the correct bolt patterns, bearing journal diameters, and ring gear mounting flange. Following the casting process, critical surfaces are machined to exacting tolerances. This ensures perfect ring gear alignment, which is paramount for quiet operation and efficient power transfer, and guarantees a precise fit with the axle's existing carrier bearings and other internal components, facilitating a straightforward installation.

Performance and Direct Application
The primary function of this standard open differential case is to house the spider gears and side gears, allowing the wheels to rotate at different speeds during turns while distributing power. The CroCrown 44590 is designed to restore this essential function to factory specifications. It is the ideal replacement for a damaged or worn original case and is fully compatible with the stock gear ratios. By ensuring all internal components are correctly aligned, this case helps prevent premature wear on ring and pinion gears, protecting your investment in the axle rebuild.

For a reliable, direct-fit, and affordable solution for your Dana 35 axle repair, the CroCrown Automotive 44590 Differential Case offers the quality and compatibility needed for a successful and lasting repair, getting your classic Jeep back on the road with confidence.
