ZF 5838.300.350 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 5838.300.350 REAR AXLE HOUS. is a critical structural component designed to encase and protect the differential assembly within heavy-duty construction machinery drivelines. As an OEM genuine part, this housing provides the rigid mounting points for the axle shafts and bearings, ensuring precise gear alignment under extreme loads. The SKU 5838.300.350 sits directly between the final drive and the main transmission output, serving as the primary load-bearing shell that absorbs torsional stress and road shock. Without this housing, the internal 5838109002: DIFFERENTIAL would lack the necessary support to transfer torque effectively to the wheels.

Symptoms of Failure

• Hypoid oil seepage around the axle tube weld: When the housing develops micro-fractures, gear oil begins weeping from the seam between the tube and the central carrier, leaving visible drips on the undercarriage.
• Persistent gear whine during loaded turns: A worn housing bore allows the 0750117075: TAPER ROLLER BEARING to shift, creating uneven tooth contact that produces a high-pitched howl under torque.
• Increased backlash at the wheel hub: Cracks in the housing flange cause the 5838300128: DIFFERENTIAL HOUSING to misalign, resulting in a clunking sensation when shifting between forward and reverse.
• Metal debris in the differential oil: Spalling from the housing interior surface contaminates the lubricant, often accompanied by a grinding noise during straight-line operation.

Technical Specifications

Compatibility

This rear axle housing is engineered for ZF WG-series powershift transmissions commonly deployed in wheel loaders, graders, and telehandlers. It is a direct fit for the WG180 and WG200 series, as well as the WG310 heavy-duty variant. The housing also integrates with the 4WG-200 and 6WG-310 drivelines. When replacing this part, always inspect the 0631329086: SPRING PIN that secures the housing to the axle beam, as reuse can lead to fastener fatigue.
