Dana 30 3.08 Ratio Axle Assembly

The Zumbrota Drivetrain RAA434-1480A is a remanufactured axle assembly specifically built for the Dana 30 differential, featuring a 3.08 gear ratio and a 7.12-inch ring gear size. This assembly is meticulously rebuilt to exacting standards, ensuring precision and long-term reliability for your vehicle's drivetrain. During the remanufacturing process, each axle assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are fully inspected and tested. To guarantee optimal performance and longevity, all bearings and seals are replaced with new ones. The gears are inspected for ideal tooth contact patterns, and correct rolling torque is established using inch-pound measurements. Gear backlash is precisely set to ensure proper lubrication and quiet operation, meeting OEM specifications for straightness. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary deep cleaning process, to prepare both internal and external parts. This meticulous cleaning method ensures that all housings are restored to an OEM finish, setting a high standard for axle assembly remanufacturing. It's important to note that this assembly includes the main housing and internal components only; it does not come with axles, ball joints, spindles, steering components, or brakes. This remanufactured axle assembly is designed for 1987-1989 Jeep Wrangler models. It comes with a 2-year limited warranty for peace of mind.
