ZF 4644.104.201 DIFFERENTIAL for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.104.201 DIFFERENTIAL is a critical torque-distributing assembly engineered for the WG 180 and WG 200 series transmissions. This OEM genuine part manages the speed difference between the left and right drive wheels while transferring engine power from the axle drive housing to the final drives. Positioned within the rear axle assembly, the differential works in concert with the 4460115043: HOUSING to ensure smooth cornering and consistent traction under heavy loads. The SKU 4644.104.201 is precision-machined to ZF factory tolerances, guaranteeing a direct replacement without modification.

Symptoms of Failure

• Whining or howling noise during turns: A worn differential produces a distinct metallic whine when cornering, indicating gear tooth wear or bearing play. This symptom often escalates with speed.
• Oil leakage around the axle housing: Degraded seals or a cracked differential case cause gear oil to seep past the 4469315012: AXLE DRIVE HOUSING, leaving visible puddles under the vehicle.
• Clunking or lurching on acceleration: Excessive backlash from worn spider gears or side gears creates a noticeable clunk when shifting from drive to reverse or under sudden throttle application.
• Vibration at highway speeds: Imbalanced differential components transmit vibration through the driveline, often mistaken for tire or driveshaft issues.

Technical Specifications

Compatibility

This differential is specifically designed for ZF WG 180 and WG 200 series transmissions used in heavy-duty construction, agricultural, and material handling equipment. It directly replaces the original unit in models such as the WG 180, WG 200, and WG 200/II. The part also integrates with earlier WG 160 variants when paired with the correct 4460115043: HOUSING assembly. Always verify the axle housing configuration—the 4469315012: AXLE DRIVE HOUSING must match the differential flange pattern for proper installation.
