ZF 4950.103.002 OUTPUT for WG92/WG98 | OEM Genuine Part

Overview

The ZF 4950.103.002 OUTPUT for WG92/WG98 is a critical driveline component engineered to transfer rotational force from the transmission’s planetary gear set to the output flange. Positioned at the rear of the gearbox housing, this OEM genuine part ensures precise torque delivery and alignment under heavy-duty loads. The SKU 4950.103.002 interfaces directly with the 4950101004: HOUSING and the 4950301018: HOUSING I, forming a sealed assembly that withstands high axial forces. Manufactured to ZF’s original tolerances, this output shaft eliminates play and maintains consistent power flow in WG92 and WG98 series transmissions.

Symptoms of Failure

• Oil seepage near the rear flange: A worn output shaft often causes fluid to bypass the 0734309932: SHAFT SEAL, leading to visible drips and low transmission fluid levels.
• Vibration during acceleration: Excessive radial play in the 4950.103.002 output produces driveline shudder, especially under load between 30–50 mph.
• Clunking or knocking sounds: When the splines degrade, gear engagement becomes erratic, creating audible metallic impacts during shifts.
• Intermittent power loss: A failing output shaft can cause torque interruption, resulting in hesitation or slipping when climbing grades.

Technical Specifications

Compatibility

This output shaft is specifically designed for ZF WG92 and WG98 series transmissions, including the WG180, WG200, and WG210 variants. It also fits select WG120 and WG150 models when paired with the correct 4660101023: TRANSMISSION HOUSING. Always verify the spline profile and bearing seat dimensions before installation. The 4950.103.002 output is not interchangeable with earlier WG80 series units due to differences in flange bolt patterns.
