ZF 4660.305.038 OUTPUT SHAFT for WG92/WG98 | OEM Genuine Part

Overview

The ZF 4660.305.038 OUTPUT SHAFT is a critical drivetrain component engineered specifically for the WG92 and WG98 transmission series. This OEM genuine part transmits rotational torque from the planetary gearset to the final drive, ensuring smooth power delivery under heavy load conditions. Machined from high-strength alloy steel, the output shaft interfaces directly with the TRANSMISSION HOUSING and the HOUSING II to maintain precise axial alignment. The SKU 4660.305.038 is a direct replacement for original factory equipment, eliminating guesswork during rebuilds or repairs.

Symptoms of Failure

• Transmission oil leaks at the rear seal: A worn output shaft bearing journal or seal surface allows fluid to escape, often visible as drips under the bell housing.
• Gear slipping under load: Excessive shaft play causes misalignment between the output flange and planetary carrier, leading to intermittent power loss during acceleration.
• Vibration or driveline shudder: A fatigued shaft develops microscopic cracks or spline wear, producing rhythmic vibrations that intensify at highway speeds.
• Metallic grinding noises: Worn splines on the output shaft fail to engage the companion flange properly, creating a distinct grinding sound during gear engagement.

Technical Specifications

Compatibility

This output shaft is designed for ZF WG series transmissions with a modular rear-mount configuration. Verified compatible models include the WG92, WG98, WG180, and WG200 series. It also fits select variants of the WG120 and WG150 when used with the correct CYLINDRICAL PIN for alignment. Always verify the TYPE PLATE on your transmission housing to confirm model designation before ordering.
