ZF 5838.117.032 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 5838.117.032 REAR AXLE HOUS. is a critical structural component within the final drive assembly of heavy-duty construction machinery transmissions. This OEM genuine part serves as the rigid casing that encloses the differential gears, bearings, and axle shafts, ensuring precise alignment under extreme torque loads. The SKU 5838.117.032 is specifically engineered to withstand high-impact stresses from earthmoving equipment, providing a sealed environment that protects internal lubricants from contamination. As the central housing for the rear axle system, it directly interfaces with the 5838109021: DIFFERENTIAL and the 2095209019: DIFFERENTIAL to distribute power evenly to the wheels.

Symptoms of Failure

• Visible oil seepage from axle seals: Cracks or porosity in the housing casting often lead to gradual lubricant loss, leaving puddles under parked equipment.
• Excessive drivetrain noise during turns: A worn housing can misalign the 0750117075: TAPER ROLLER BEARING, causing a distinct grinding or howling sound when maneuvering.
• Vibration under load: Structural fatigue in the housing allows the differential assembly to shift, producing noticeable chassis vibration during excavation or grading operations.
• Metal debris in differential oil: Internal housing fractures generate metallic particles that contaminate the lubricant, often discovered during routine oil analysis.

Technical Specifications

Compatibility

This rear axle housing is designed for ZF’s heavy-duty powershift transmission series commonly found in wheel loaders and graders. It is a direct fit for the WG180 and WG200 transmission models, as well as the WG160 series in certain configurations. The housing accommodates the 0631329086: SPRING PIN for precise alignment of internal components. Always verify your transmission model number before ordering, as variations exist between early and late production units.
