High-quality, Brand New Truck Parts Truck Spare Parts Dongfeng Axle Parts Housing of Rear Axle Assy 24D-01020-B2

The 24D-01020-B2 Differential Housing Cover Assembly, commonly known as the rear axle cover, is a critical structural and sealing component designed for use in Dongfeng Commercial Vehicles’ drive axle systems. This part mounts on the rear of the axle housing, enclosing the differential assembly to maintain lubricant containment, protect internal gears, and assist in heat dissipation during operation.

Manufactured primarily by Dongfeng Dana (Dongfeng-Dana joint venture), this cover is engineered for durability and reliability under heavy-duty conditions. Its bowl-shaped design increases internal oil capacity and promotes effective lubrication circulation around the ring and pinion gears. The cover also provides access points for oil inspection, filling, and draining—making it essential for routine maintenance.
