ZF 5838.300.133 COMPENS. STUB AXLE | OEM Genuine Part

Overview

The ZF 5838.300.133 COMPENS. STUB AXLE is a precision-machined component located within the differential assembly of heavy-duty construction machinery transmissions. This genuine OEM part functions as a pivot point for the compensating gears, enabling smooth torque distribution between the drive wheels during turns and uneven terrain operation. As a critical element of the differential system, the stub axle works in concert with the DIFFERENTIAL HOUSING and the DIFFERENTIAL to maintain proper gear alignment. The SKU 5838.300.133 is engineered to exact OEM tolerances, ensuring reliable load transfer and extended service life in demanding environments such as wheel loaders, graders, and dozers.

Symptoms of Failure

• Excessive drivetrain noise during turns: A worn compens. stub axle causes the differential bevel gears to misalign, producing a distinct grinding or clunking sound when the machine maneuvers under load.
• Uneven tire wear or reduced traction: As the stub axle surface degrades, torque distribution becomes erratic, leading to one wheel spinning faster than the other on loose surfaces.
• Oil contamination from metal particles: Fatigue fractures on the stub axle generate metallic debris that circulates through the transmission fluid, often visible during routine oil changes.
• Vibration through the chassis: A failing stub axle introduces play in the differential assembly, causing noticeable vibration at speeds above 10 mph, particularly in articulated loaders.

Technical Specifications

Compatibility

This compens. stub axle is primarily used in ZF WG180, WG200, and WG310 series transmissions found in construction machinery. It is a direct replacement for the COMPENS. STUB AXLE (5838300132) in earlier production runs. The part interfaces with the REAR AXLE assembly and requires the TAPER ROLLER BEARING (0750117075) for proper installation. Always verify transmission model and serial number before ordering.
