ZF 5838.300.815 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 5838.300.815 REAR AXLE HOUS. is a structural core component within heavy-duty construction machinery drivelines. This OEM genuine housing encloses the differential assembly and supports the axle shafts, ensuring precise gear alignment under extreme torque loads. As the primary load-bearing shell, it protects internal gearsets from contaminants while maintaining lubricant integrity. The SKU 5838.300.815 is specifically engineered for ZF’s modular axle system, providing the rigid mounting points required for planetary gear sets and final drives in wheel loaders and graders.

Symptoms of Failure

• Oil seepage at axle tube seals: Cracks or porosity in the housing casting cause gradual lubricant loss, visible as wet patches near the wheel ends. This often leads to rear axle housing oil leak repair searches.
• Abnormal gear whine during turns: Distortion of the housing bore allows the 5838109023: DIFFERENTIAL to misalign, creating a cyclical howl that intensifies under load.
• Premature bearing failure: Housing wear at the 0750117075: TAPER ROLLER BEARING seats results in radial play, causing vibration felt through the chassis during acceleration.
• Contaminated lubricant: Fractures in the housing allow ingress of water and debris, turning the gear oil milky and accelerating wear on the 2095209037: DIFFERENTIAL assembly.

Technical Specifications

Compatibility

This rear axle housing is designed for ZF’s WG180 and WG200 series transmissions commonly found in articulated dump trucks and telehandlers. It also integrates with the 2095309059: DIFF.HOUSING in the APL-300 axle range. The casting accommodates both standard and limited-slip differential carriers, making it a direct replacement for models with serial numbers beginning 5838. Verify your transmission tag before ordering.
