ZF 5838.056.012 REAR AXLE | OEM Genuine Part

Overview

The ZF 5838.056.012 REAR AXLE is a critical OEM genuine component engineered for heavy-duty construction machinery. This part serves as the primary torque-transmitting hub within the final drive assembly, connecting the differential output directly to the wheel hubs. Designed to withstand extreme axial and radial loads, the SKU 5838.056.012 sits at the terminal point of the ZF transmission system, converting rotational force into tractive effort. When paired with a matching 5838109023: DIFFERENTIAL, this rear axle ensures precise power distribution even under the harshest operating conditions.

Symptoms of Failure

• Persistent oil seepage around the wheel end seal: A worn rear axle often compromises the sealing surface, leading to gradual lubricant loss. This is a common long-tail search query for “ZF rear axle oil leak repair.”
• Intermittent gear slipping during load cycles: When the axle splines or bearing journals wear, you may experience momentary loss of drive engagement, especially when reversing under load.
• Abnormal lateral play in the wheel hub: Excessive clearance indicates that the axle shaft or its supporting 0750117075: TAPER ROLLER BEARING has degraded, requiring immediate replacement to prevent catastrophic failure.
• Metallic grinding noise from the axle housing: This symptom typically signals debris contamination or advanced spalling on the axle shaft surface, often linked to a failing 2095209037: DIFFERENTIAL assembly.

Technical Specifications

Compatibility

This OEM genuine rear axle is designed for integration into ZF’s WG180, WG200, and WG310 series transmissions commonly deployed in wheel loaders, graders, and telehandlers. It is a direct replacement for units originally fitted with the 2095309059: DIFF.HOUSING. Always verify the axle flange pattern against your existing housing to ensure correct fitment.
