ZF 4644.303.368 OUTPUT SHAFT for WG200 | OEM Genuine Part

Overview

The ZF 4644.303.368 OUTPUT SHAFT is a critical torque-transfer component engineered specifically for the WG 200 series heavy-duty transmissions. This OEM genuine part transmits rotational force from the planetary gear set to the driveline flange, ensuring smooth power delivery under extreme load conditions. The SKU 4644.303.368 is precision-machined to interface directly with the TRANSMISSION HOUSING (4644101235) and the TRANSMISSION HOUSING (4644301310), forming the backbone of the output module. Its splined geometry and hardened bearing journals are designed to withstand continuous high-torque operation in commercial vehicles and industrial machinery.

Symptoms of Failure

• Output flange oil leakage: Worn seal surfaces on the 4644.303.368 shaft allow transmission fluid to escape past the output seal, leaving puddles under the vehicle.
• Driveline vibration under load: A fatigued or bent output shaft causes noticeable shuddering during acceleration, particularly at highway speeds.
• Intermittent gear slipping: When the shaft splines wear, torque transfer becomes inconsistent, leading to momentary loss of drive in forward or reverse gears.
• Metallic grinding noise: Bearing race damage on the shaft produces a distinct grinding sound from the rear of the transmission housing.

Technical Specifications

Compatibility

This output shaft is primarily designed for the ZF WG 200 series, including the WG200, WG210, and WG220 models. It also fits select WG180 variants that share the same output module architecture. The 4644.303.368 shaft works in conjunction with the SHIFT SYSTEM (4644106301) and the TYPE PLATE (0730365067) for correct identification. Always verify the output housing configuration before installation.
