ZF 5838.117.019 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 5838.117.019 REAR AXLE HOUSING is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part encases the differential and axle shafts, providing the rigid support necessary to transfer torque from the transmission to the wheels. As the primary load-bearing shell, it maintains precise gear alignment under extreme stress. The SKU 5838.117.019 is engineered to ZF’s exacting metallurgical standards, ensuring dimensional stability in high-vibration environments. When paired with a 5838109010: DIFFERENTIAL, this housing forms the sealed chamber that protects internal gears from contamination.

Symptoms of Failure

• Visible oil seepage from axle housing seals: Cracks or porosity in the housing casting allow lubricant to escape, leading to low oil levels and accelerated wear on the 0750117075: TAPER ROLLER BEARING.
• Abnormal whining or grinding during turns: A warped housing misaligns the 2093209023: DIFFERENTIAL carrier, causing gear tooth interference and metallic debris generation.
• Excessive backlash in the driveline: Housing deformation at the bearing journals permits axial play, resulting in a clunking sensation when shifting between forward and reverse.
• Uneven tire wear patterns: A compromised housing alters the pinion angle, forcing the 5838300626: DIFFERENTIAL HOUSING to operate outside its designed geometry.

Technical Specifications

Compatibility

This rear axle housing is specifically designed for ZF’s WG series powershift transmissions used in wheel loaders and graders. It is a direct fit for the WG180 and WG200 transmission models, which are common in 5-7 ton construction machinery. The housing also supports the WG150 series when equipped with the optional heavy-duty differential package. Always verify the casting number against your existing unit before installation.
