Overview
The ZF 4644.305.040 OUTPUT SHAFT is a critical rotating component engineered specifically for the WG 200 series transmissions. This OEM genuine part transmits torque from the planetary gearset to the output flange, ensuring smooth power delivery to the driveline. Located at the rear of the transmission housing, the output shaft interfaces directly with the OUTPUT FLANGE and is secured by the HEXAGON SCREW. Precision-machined from high-strength alloy steel, the SKU 4644.305.040 is a direct replacement for worn or damaged shafts, restoring full transmission integrity.
Symptoms of Failure
- Oil leaks at the rear seal area: A worn output shaft bearing journal or seal surface allows transmission fluid to escape, leaving puddles under the vehicle.
- Vibration during acceleration: Excessive radial play in the output shaft causes driveline shudder, especially under load between 30-50 mph.
- Gear slipping or delayed engagement: A damaged shaft spline prevents proper torque transfer from the planetary carrier, leading to erratic shifting.
- Metallic grinding noise: Worn shaft bearings produce a distinct grinding sound that intensifies with speed, indicating imminent failure.
