ZF 4644.104.476 DIFFERENTIAL for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.104.476 DIFFERENTIAL is a critical power distribution component engineered specifically for the WG 180 and WG 200 series transmissions. This OEM genuine part sits within the rear axle assembly, precisely managing torque split between the drive wheels while allowing for speed differences during cornering. As a core element of the drivetrain, the 4644.104.476 differential ensures smooth, reliable power transfer under heavy industrial loads. The SKU 4644.104.476 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn units in WG 200 and WG 180 gearboxes. When paired with a robust 4644101178: TRANSMISSION HOUSING or a 4644301223: TRANSMISSION HOUSING, this differential maintains the structural integrity required for demanding applications.

Symptoms of Failure

• Whining or howling noise from the differential during turns: Worn internal gears or bearings produce a distinct audible sound, especially when cornering under load. This is a common long-tail search query for “ZF differential noise when turning.”
• Oil leaks around the differential housing: Degraded seals or gaskets allow transmission fluid to escape, often visible as drips near the axle connection. Search terms like “ZF WG200 differential oil leak” frequently target this issue.
• Vibration or shuddering during acceleration: Excessive play in the differential gears causes driveline shudder, particularly when starting from a stop or climbing inclines. This symptom is often searched as “ZF differential vibration under load.”
• Uneven tire wear or traction loss: A failing differential fails to distribute torque evenly, leading to premature tire wear or wheel spin on slippery surfaces. This aligns with queries for “differential failure symptoms ZF.”

Technical Specifications

Compatibility

This differential is designed for ZF WG 180 and WG 200 series transmissions. It is a direct fit for models including WG180, WG200, and their variants used in construction, agricultural, and material handling equipment. The part integrates seamlessly with the 0730365067: TYPE PLATE for proper identification and the 0631311009: GROOVED STUD for secure mounting. Always verify your transmission serial number against the OEM parts list to ensure compatibility.
