Introduction to the Changan Rear Axle

The Changan Rear Axle is a fully-assembled, drop-in commercial vehicle axle engineered for Changan Star trucks, Ruixing vans, and other 1–2 ton platforms. Built with forged-steel housings and CNC-machined gears, this heavy-load drivetrain restores factory load capacity while extending service intervals—making it the go-to OEM-grade replacement axle for fleet managers who demand zero downtime.

Forged 45# Steel Housing for Ultimate Strength

At the heart of the Changan Rear Axle sits a one-piece, hot-forged 45# steel center section rated at 3.2 tons static load. Finite-element analysis shows 30 % higher torsional stiffness versus cast housings, so the Changan Rear Axle resists axle tramp and housing flex even when the cargo bay is maxed out.

Helical-Hypoid Gears for Quiet, Efficient Power Transfer

The commercial vehicle axle uses Gleason-form helical-hypoid gears cut to AGMA 10 precision. This gear geometry lowers NVH by 4 dB and improves driveline efficiency by 2.7 % compared to straight-cut designs—critical gains for last-mile delivery fleets running the heavy-load drivetrain 14 hours a day.

Sealed, Maintenance-Free Bearings

Double-lip NOK seals and high-temp lithium-complex grease keep the Changan Rear Axle bearings lubricated for 200,000 km. A patented vented hub cap equalizes pressure during altitude changes, eliminating water ingestion and turning routine greasing into a simple visual check—perfect for OEM-grade replacement axle installs in under 90 minutes.

E-Coat Corrosion Shield & 5-Year Unlimited-Mile Warranty

The Changan Rear Axle receives a cathodic e-coat plus powder topcoat that passes 1,000-hour salt-spray testing. Backed by a 5-year unlimited-mile warranty against housing cracks or gear spalling, this heavy-load drivetrain delivers A-grade strength, B-level efficiency, C-tier zero-maintenance convenience, and D-tier longevity.

Conclusion

From forged-steel strength to sealed-hub simplicity, the Changan Rear Axle redefines what a commercial vehicle axle should deliver. Install once and keep your fleet rolling stronger, quieter, and longer than ever before.
