Overview
The ZF 4657.304.005 OUTPUT SHAFT is a critical driveline component engineered specifically for the WG 210 Series transmission. This OEM genuine part transfers rotational torque from the planetary gear set to the vehicle’s drive shaft, ensuring precise power delivery under heavy-duty conditions. As the final mechanical link before the output flange, the shaft must withstand high torsional loads and maintain concentric alignment. The SKU 4657.304.005 is manufactured to ZF’s original tolerances, guaranteeing a direct fit without modification. When paired with the TRANSMISSION HOUSING and the HOUS.FRONT SECT, this output shaft completes the rear power transfer assembly.
Symptoms of Failure
- Transmission output flange oil seepage – Worn splines or a damaged sealing surface on the shaft allow ATF to leak past the rear seal, leaving visible drips under the vehicle.
- Vibration during acceleration at highway speeds – A bent or fatigued output shaft creates rotational imbalance, causing driveline shudder that intensifies under load.
- Intermittent gear slipping in reverse or low range – Excessive spline wear reduces engagement depth with the mating hub, leading to torque loss and erratic shifting.
- Metallic grinding noise from the rear of the transmission – Bearing journal scoring or pitting on the shaft produces a distinct whirring or grinding sound as the shaft rotates.

Compatibility
This output shaft is designed for the ZF WG 210 Series, but it also fits select models in the WG180 and WG200 families due to shared rear housing geometry. It is directly compatible with transmissions that use the HOUSING REAR PART and the CYLINDRICAL PIN for alignment. Always verify your transmission’s serial number against ZF’s parts catalog before installation.
