Overview
This OEM genuine ZF 2093.303.086 GEAR is a critical component engineered for the WG100, WG130, and WG131 transmission series. Positioned within the final drive assembly, this gear directly transfers torque from the differential to the axle shafts, ensuring smooth power delivery under heavy loads. The SKU 2093.303.086 is precision-machined to ZF’s exacting tolerances, making it a direct replacement for worn or damaged gears. When paired with a properly functioning DIFFERENTIAL, this gear maintains optimal drivetrain alignment and reduces parasitic power loss.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth cause uneven contact patterns, producing a distinct high-pitched sound that intensifies under load.
- Vibration in the driveline at highway speeds: A damaged 2093.303.086 gear creates rotational imbalance, felt as a shudder through the chassis or steering wheel.
- Metal debris in transmission fluid: Flaking or chipped gear teeth contaminate the oil, often visible as glitter-like particles during fluid changes.
- Intermittent loss of power to wheels: Severe wear can cause the gear to skip teeth, resulting in sudden torque interruptions during gear engagement.

Frequently Asked Questions
Q: Can I install the 2093.303.086 gear without replacing the taper roller bearing?
A: It is strongly recommended to replace the TAPER ROLLER BEARING simultaneously, as worn bearings accelerate gear tooth wear and cause misalignment.
Q: How do I confirm this gear fits my WG130 transmission?
A: Verify your transmission’s serial number against ZF’s parts catalog. The 2093.303.086 gear is compatible with WG130 units built after 2012, but always cross-check with the differential housing part number.
Q: What torque specification is required for the retaining nut?
A: The retaining nut should be torqued to 280 Nm (206 ft-lbs) for WG100/WG130 models. Always use a new spring pin (0631329088) to lock the nut after tightening.
