Overview
The ZF 2093.298.140 GEAR is a precision-machined helical gear designed for the differential assembly within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transfers torque from the input shaft to the differential carrier, enabling smooth power distribution to the axle shafts. As a critical component of the final drive, it directly influences load capacity and noise reduction. The SKU 2093.298.140 is manufactured to ZF’s exacting tolerances, ensuring seamless meshing with mating gears. When installed alongside a DIFFERENTIAL and a TAPER ROLLER BEARING, this gear maintains proper backlash and axial preload for extended service life.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth create irregular contact patterns, producing a distinct high-pitched sound that intensifies under load. This often signals the need for immediate replacement of the 2093.298.140 gear.
- Vibration in the driveline at highway speeds: As the gear surface degrades, rotational imbalance develops, causing noticeable shuddering through the chassis. This symptom frequently accompanies a failing DIFFERENTIAL assembly.
- Oil leaks from the differential housing: Excessive gear wear generates metal particles that can damage seals. If you observe fluid seepage near the DIFF.HOUSING, inspect the gear set immediately.
- Intermittent gear slipping or clunking: Advanced tooth wear causes loss of positive engagement, leading to momentary power loss or audible clunks when shifting between forward and reverse.

Compatibility
This genuine ZF gear is engineered specifically for the WG100, WG130, and WG131 transmission series. It is also compatible with select WG180 and WG200 variants that share the same differential architecture. Always verify your transmission model tag before ordering. For optimal performance, pair this gear with a new TAPER ROLLER BEARING and inspect the DIFF.HOUSING for wear during installation.

Frequently Asked Questions
Q: Can I replace the 2093.298.140 gear without removing the entire transmission?
A: Yes, in most WG100/WG130 applications, the differential cover can be removed to access this gear. However, you must also replace the TAPER ROLLER BEARING and inspect the DIFF.HOUSING for scoring.
Q: How do I verify this gear is genuine ZF and not a counterfeit?
A: Genuine parts feature laser-etched part numbers and ZF logos on the gear face. The 2093.298.140 should also have a distinct case-hardened surface that resists file testing.
Q: What is the typical service life of this gear under normal operating conditions?
A: With proper lubrication and load management, this gear typically lasts 8,000–12,000 operating hours. Premature failure often results from contaminated oil or misaligned DIFFERENTIAL components.
