ZF 0501.210.375 END YOKE for WG92

Overview

The ZF 0501.210.375 END YOKE is a critical driveline interface component engineered specifically for the WG 92 Series transmission family. This OEM genuine part serves as the mechanical coupling point between the transmission output shaft and the driveshaft, transmitting rotational torque while accommodating minor angular misalignment. Positioned at the rear of the transmission assembly, the end yoke ensures secure power transfer from the gearbox to the vehicle’s driveline. The SKU 0501.210.375 is precision-machined to ZF’s exacting tolerances, guaranteeing a spline-fit that eliminates play and reduces vibration under heavy load conditions. When installed alongside the 4660198001: PERIPHERALS kit, this yoke completes the output-side sealing and retention system for the WG92.

Symptoms of Failure

When the ZF 0501.210.375 END YOKE begins to wear, operators often notice driveline vibration at highway speeds that intensifies during acceleration or deceleration—a common long-tail search query for fleet managers. A second failure symptom is transmission fluid seepage from the output seal area, as a worn yoke surface damages the sealing lip. Third, clunking or thumping noises when shifting between drive and reverse indicate excessive spline wear between the yoke and output shaft. Finally, premature U-joint failure on the driveshaft can occur if the yoke’s pilot bore becomes ovalized, causing misalignment that stresses downstream components.

Technical Specifications

Compatibility

This end yoke is designed for the ZF WG 92 Series, which includes the WG92, WG120, and WG150 transmission models commonly found in medium-duty trucks, buses, and off-highway equipment. It also fits select WG180 and WG200 variants where the output shaft spline count and pilot diameter match. For proper installation, the yoke must be paired with the 0501209818: RANGE SELECTOR assembly, which controls the planetary gearset engagement. The yoke’s housing interface aligns with the 4660101011: TRANSMISSION HOUSING and the 4660301018: HOUSING cover, ensuring concentricity during torque transmission. Always verify the output shaft end-play before torquing the yoke retaining nut to ZF specifications.
