Overview
This ZF 2093.109.055 DIFFERENTIAL is an OEM genuine component engineered for heavy-duty construction machinery drivelines. Positioned within the final drive assembly, this differential distributes torque evenly between the axle shafts, allowing wheels to rotate at different speeds during turns. The SKU 2093.109.055 is a direct replacement part designed to restore factory-spec performance in ZF transmissions, working in concert with the 2093209094 DIFFERENTIAL and the 2093309078 DIFF.HOUSING to ensure precise gear meshing and load distribution.
Symptoms of Failure
- Oil leaks from the axle housing: Worn seals or cracks in the differential case cause lubricant to escape, often visible as drips under the machine. This is a common sign the 2093.109.055 unit needs replacement.
- Gear slipping or clunking during turns: Damaged internal gears or worn spider gears lead to intermittent torque transfer, producing audible clunks or a sensation of slipping when maneuvering.
- Excessive drivetrain vibration: A failing differential can cause uneven rotation, resulting in vibrations felt through the chassis, especially at low speeds or under load.
- Abnormal tire wear patterns: When the differential fails to equalize wheel speeds, one tire may scrub or wear faster than the other, indicating internal component fatigue.

Compatibility
This differential is engineered for ZF heavy-duty transmission models commonly found in construction machinery. It is compatible with the WG180, WG200, and WG250 series transmissions, as well as select off-highway applications using the ZF 4WG-200 and 6WG-250 platforms. Always verify your transmission model and axle configuration before ordering. The 2093.109.055 integrates directly with the 2093309078 DIFF.HOUSING and requires the 0750117075 TAPER ROLLER BEARING for proper support.

Frequently Asked Questions
Q: How do I know if the 2093.109.055 differential is failing?
A: Listen for grinding noises during turns or check for oil leaks near the axle housing. Vibration under load and uneven tire wear are also strong indicators that this part requires replacement.
Q: Can I install this differential without replacing the taper roller bearing?
A: It is strongly recommended to replace the 0750117075 TAPER ROLLER BEARING simultaneously, as worn bearings can damage the new differential and reduce service life.
Q: Is this part compatible with ZF WG180 transmissions?
A: Yes, the 2093.109.055 is designed for WG180, WG200, and WG250 series transmissions used in construction machinery. Confirm your axle configuration before purchase.
