ZF 2095.117.021 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2095.117.021 REAR AXLE HOUSING is a critical structural component within heavy-duty construction machinery drivelines. This OEM genuine part encases the differential assembly and axle shafts, providing the rigid support necessary to transfer torque from the transmission to the wheels. As the central load-bearing shell, it maintains precise gear alignment under extreme stress. The SKU 2095.117.021 is engineered to ZF’s exacting tolerances, ensuring a seamless fit with internal rotating elements like the 2095109011 DIFFERENTIAL and the 2095209037 DIFFERENTIAL assembly.

Symptoms of Failure

• Persistent gear oil seepage from housing seams: Cracks or porosity in the casting allow lubricant to escape, leading to low fluid levels and accelerated internal wear.
• Abnormal whining or grinding during turns: A warped or misaligned housing disrupts the mesh pattern of the 0750117075 TAPER ROLLER BEARING, generating audible distress under load.
• Vibration through the chassis at low speeds: Structural fatigue in the housing can cause the 2095309059 DIFF.HOUSING to flex, transmitting oscillation into the vehicle frame.
• Metal debris in drained oil: Internal spalling from housing-mounted bearing journals indicates imminent structural failure requiring immediate replacement.

Technical Specifications

Compatibility

This rear axle housing is primarily specified for ZF WG180 and WG200 series powershift transmissions used in wheel loaders, telehandlers, and graders. It also fits select ZF APL-300 and APL-400 axle configurations. The casting accommodates both standard and limited-slip differential carriers. Always verify the housing flange pattern against your existing 2095309059 DIFF.HOUSING before installation.
