ZF 5838.053.009 REAR AXLE | OEM Genuine Part

Overview

The ZF 5838.053.009 REAR AXLE is a critical OEM genuine component engineered for the final drive assembly in heavy-duty construction machinery. This part transmits rotational power from the differential to the wheel hubs, ensuring stable torque delivery under extreme loads. As a factory-spec replacement, the SKU 5838.053.009 integrates directly into ZF’s planetary gear sets, supporting both load-bearing and traction functions. When paired with a properly functioning 5838109023: DIFFERENTIAL, this rear axle maintains precise alignment within the axle housing, reducing vibration and extending service life in excavators and wheel loaders.

Symptoms of Failure

• Oil leaks near the wheel end seal: Worn axle journals or seal surfaces cause fluid seepage, often visible as drips around the hub flange.
• Intermittent gear slipping under load: A failing rear axle can cause momentary loss of drive torque when climbing grades or digging, due to spline wear.
• Metallic grinding noise during turns: Damaged bearing seats or axle shaft distortion produce a low-pitched growl, especially when the machine articulates.
• Excessive backlash in the driveline: Loose axle-to-differential coupling leads to a clunking sensation when shifting between forward and reverse.

Technical Specifications

Compatibility

This rear axle is designed for ZF WG180, WG200, and WG310 series transmissions commonly used in construction machinery. It also fits select models of the ZF 4WG-180 and 4WG-200 power shift transmissions. The part interfaces directly with the 2095209037: DIFFERENTIAL and requires the 0750117075: TAPER ROLLER BEARING for proper axial support. For complete assembly, the 2095309059: DIFF.HOUSING must be inspected for cracks or warpage during installation.
