Overview
The ZF 5838.300.131 Axle Bevel Gear is a critical power-transfer component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part sits within the final drive assembly, where it meshes directly with the ring gear to convert rotational force from the driveshaft into torque for the axles. As a precision-ground bevel gear, it ensures smooth, quiet operation under heavy loads. The SKU 5838.300.131 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and long service life in industrial drivetrains. This gear works in concert with the 5838022003: REAR AXLE to deliver reliable power to the wheels, and it interfaces with the 5838109001: DIFFERENTIAL to manage speed differences between wheels during turns.
Symptoms of Failure
When the ZF 5838.300.131 Axle Bevel Gear begins to wear, operators will notice distinct performance issues. Whining or howling noise from the axle housing during acceleration or deceleration is the most common early indicator, often caused by improper tooth contact or pitting. Vibration in the driveline at specific speeds signals that the gear’s tooth profile has degraded, leading to uneven load distribution. Metallic debris in the differential oil is a clear sign of spalling or chipping on the bevel gear surface. Finally, intermittent loss of drive power or a clunking sensation when shifting between forward and reverse suggests the gear has suffered tooth breakage or severe backlash wear. Ignoring these symptoms can damage the 5838300128: DIFFERENTIAL HOUSING and other internal components.

Compatibility
This genuine ZF bevel gear is specifically designed for the following transmission models: WG100, WG130, and WG131. It is also compatible with certain variants of the WG180 and WG200 series that share the same final drive architecture. Always verify the axle ratio and housing casting number before installation. The gear mates directly with the 5838300134: DIFFERENTIAL BEVEL GEAR and is supported by the 0750117075: TAPER ROLLER BEARING for precise axial positioning. For complete axle rebuilds, the 5838300132: COMPENS. STUB AXLE and 5838300133: COMPENS. STUB AXLE are often replaced simultaneously.
