ZF 5838.056.005 REAR AXLE | OEM Genuine Part

Overview

The ZF 5838.056.005 REAR AXLE is a critical load-bearing and torque-transmitting component engineered for heavy-duty construction machinery. This OEM genuine part sits at the final drive stage of the transmission assembly, transferring rotational power from the differential unit directly to the wheel hubs. Designed to withstand extreme axial and radial loads, the 5838.056.005 ensures precise alignment of the axle shafts within the housing. When paired with a robust DIFF.HOUSING, this rear axle maintains drivetrain integrity under the harshest operating conditions. The SKU 5838.056.005 is manufactured to ZF’s original tolerances, guaranteeing a direct fit and long service life in wheel loaders, graders, and heavy excavators.

Symptoms of Failure

• Persistent oil seepage from axle seals: Worn splines or a cracked axle shaft can compromise seal contact, leading to gear oil leaks around the hub flange.
• Abnormal clunking during acceleration or deceleration: Excessive backlash in the axle splines or bearing journals creates audible metallic impacts, especially under load.
• Vibration at the wheel end: A bent or fatigued rear axle causes cyclic imbalance, felt as steering wheel shake or chassis vibration at low speeds.
• Uneven tire wear and driveline shudder: Misalignment from a failing axle forces the differential to work harder, accelerating wear on the DIFFERENTIAL and DIFFERENTIAL gears.

Technical Specifications

Compatibility

This rear axle is a direct replacement for ZF heavy-duty transmission families commonly found in construction equipment. It is specifically engineered for the WG180 and WG200 series power shift transmissions. The part also integrates with select WG150 and WG250 configurations where the axle shaft length and spline count match. Always verify the housing bore dimensions; this axle pairs with the TAPER ROLLER BEARING (part 0750117075) for proper preload. For complete assembly, it works in tandem with the DIFFERENTIAL AXLE (2095309081) to distribute torque evenly.
