Overview
The ZF 2093.268.018 OUTPUT SHAFT is a precision-machined component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part serves as the primary torque transfer interface between the transmission’s planetary gearset and the final drive assembly. Positioned at the rear of the gearbox housing, the output shaft (SKU: 2093.268.018) transmits rotational power directly to the differential, ensuring smooth engagement under heavy loads. Constructed from case-hardened alloy steel, it withstands high torsional stress while maintaining concentricity. For optimal drivetrain integrity, this shaft must be paired with a properly functioning 5838109012: DIFFERENTIAL and the 5838300626: DIFFERENTIAL HOUSING to maintain correct gear mesh alignment.
Symptoms of Failure
- Oil seepage at the rear seal: A worn output shaft surface or damaged splines can cause transmission fluid to leak past the seal, leaving puddles under the vehicle.
- Gear slipping under load: Excessive play in the shaft’s spline engagement leads to intermittent power loss during acceleration or hill climbing.
- Vibration during deceleration: A bent or fatigued output shaft creates rhythmic driveline shudder, particularly noticeable when coasting between 30-50 km/h.
- Metallic grinding noise: Worn bearing journals allow the shaft to contact the housing, producing a distinct grinding sound that worsens with speed.

Compatibility
This output shaft is specifically designed for ZF’s WG-series transmissions. It is a direct fit for the WG100, WG130, and WG131 models. While it shares dimensional characteristics with shafts used in the WG180 and WG200 series, those units require a different spline count. Always verify your transmission’s model tag before installation. When replacing this shaft, we strongly recommend inspecting the 0750117075: TAPER ROLLER BEARING and the 2093209023: DIFFERENTIAL for wear, as these components share the same load path.

Frequently Asked Questions
Q: Can the ZF 2093.268.018 output shaft be used in a WG180 transmission?
A: No. While the WG180 shares a similar housing design, its output shaft uses a 48 mm spline diameter. Installing this part in a WG180 will cause improper gear engagement and rapid bearing failure.
Q: How do I know if my output shaft needs replacement without removing the transmission?
A: Measure the rotational play at the yoke. If you detect more than 2 mm of radial movement at the flange, the shaft’s bearing journal is likely worn. Also check for metal particles in the transmission fluid—these often indicate spline degradation.
Q: Should I replace the taper roller bearing at the same time as the shaft?
A: Yes. The 0750117075: TAPER ROLLER BEARING often suffers brinelling from the same load cycles that wear the shaft. Replacing both components together ensures proper preload and extends service life.
