ZF 5838.023.008 REAR AXLE | OEM Genuine Part

Overview

The ZF 5838.023.008 REAR AXLE is a critical OEM genuine component designed for heavy-duty construction machinery transmissions. This part functions as the primary output shaft housing within the final drive assembly, transferring rotational torque from the differential to the wheel hubs. The SKU 5838.023.008 is precision-machined from high-tensile alloy steel to withstand extreme loads encountered in excavators, wheel loaders, and graders. It integrates directly with the 5838109021: DIFFERENTIAL and the 2095209019: DIFFERENTIAL to ensure smooth power distribution under continuous operation.

Symptoms of Failure

• Oil leaks at the axle seal interface: Worn rear axle surfaces cause fluid seepage around the hub, leading to low lubricant levels and potential gearbox overheating.
• Abnormal gear whine or grinding noise: A failing 5838.023.008 axle creates metallic scraping sounds during acceleration or deceleration, indicating bearing surface degradation.
• Uneven tire wear or vibration: Misalignment from a damaged rear axle produces rhythmic shaking in the driveline, especially at lower speeds.
• Reduced traction or wheel slippage: Internal fatigue in the axle shaft prevents proper torque transfer, causing the machine to struggle on inclines or loose terrain.

Technical Specifications

Compatibility

This rear axle is engineered for ZF WG180, WG200, and WG310 series transmissions commonly used in construction machinery. It also fits select models in the ZF Ecomat 5HP and 6HP ranges when paired with the correct differential assembly. Always verify fitment with your specific transmission serial number before installation.
