ZF 2095.317.021 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2095.317.021 REAR AXLE HOUSING is a critical structural component designed to encase and protect the differential assembly within heavy-duty construction machinery transmissions. This OEM genuine part provides the rigid mounting platform for axle shafts and bearings, ensuring precise gear alignment under extreme loads. The SKU 2095.317.021 sits at the rear of the drivetrain, directly interfacing with the DIFF.HOUSING to form a sealed enclosure for lubricant and rotating components. Its cast-iron construction withstands torsional stress from wheel hubs while maintaining dimensional stability during operation in excavators, loaders, and graders.

Symptoms of Failure

• Oil seepage at axle flange seals: Cracks or porosity in the housing cause lubricant to weep onto brake assemblies, leading to contamination and reduced braking efficiency.
• Abnormal whining or grinding noises: Warped housing surfaces misalign the DIFFERENTIAL assembly, generating metallic contact sounds during turns or under load.
• Premature bearing wear: Housing bore distortion accelerates failure of the TAPER ROLLER BEARING, causing wheel wobble and uneven tire wear patterns.
• Vibration during acceleration: Loose housing mounting points allow the DIFFERENTIAL carrier to shift, transmitting harmonics through the chassis.

Technical Specifications

Compatibility

This rear axle housing is engineered for ZF WG180, WG200, and WG210 series power shift transmissions commonly used in construction machinery. It directly replaces OEM housings on models including ZF 4WG-180, 4WG-200, and 5WG-210. The part also fits select ZF APL-300 series axles when paired with the DIFFERENTIAL AXLE kit. Always verify spline count and bolt pattern against your existing housing before installation.
