ZF 5838.300.132 COMPENS. STUB AXLE | OEM Genuine Part

Overview

The ZF 5838.300.132 COMPENS. STUB AXLE is a critical load-bearing component within the final drive assembly of heavy-duty construction machinery transmissions. This OEM genuine part serves as the pivot point for the compensating mechanism, allowing the axle shafts to articulate and maintain consistent wheel contact over uneven terrain. Positioned directly between the differential carrier and the wheel hub, the stub axle transmits torque while absorbing radial and axial stresses. The SKU 5838.300.132 is precision-machined to OEM tolerances to ensure seamless integration with the surrounding drivetrain components.

Symptoms of Failure

• Uneven tire wear and vibration during operation: When the compens. stub axle wears, it introduces play in the wheel end, causing irregular tire contact and noticeable shimmy at low speeds.
• Oil seepage from the wheel hub seal area: A worn stub axle surface damages the seal lip, leading to gear oil leaks that contaminate brake assemblies and reduce lubrication efficiency.
• Clunking or knocking noises when turning: Excessive clearance in the stub axle joint produces metallic impact sounds, particularly during sharp maneuvers or reversing.
• Reduced traction on uneven ground: Failure of this component compromises the compensating action, causing one wheel to lose grip prematurely on construction sites.

Technical Specifications

Compatibility

This compens. stub axle is engineered for ZF’s heavy-duty powershift transmission series commonly used in wheel loaders, graders, and dump trucks. It is a direct fit for the WG180, WG200, and WG250 transmission models. The part also integrates with the 4WG-200 and 6WG-250 variants. Always verify the axle housing configuration before installation, as some early WG180 units require a different spline profile.

During replacement, technicians should inspect the mating 5838022003: REAR AXLE for housing distortion and check the 5838109001: DIFFERENTIAL for gear backlash. The 0750117075: TAPER ROLLER BEARING must be replaced simultaneously to prevent premature stub axle wear. Additionally, the 5838300128: DIFFERENTIAL HOUSING should be examined for cracks at the bearing bore.
