ZF 2093.094.002 REAR AXLE | OEM Genuine Part

Overview

The ZF 2093.094.002 REAR AXLE is an OEM genuine component engineered for the demanding environment of construction machinery. This rear axle assembly serves as the primary structural and rotational interface between the differential housing and the wheel hubs, transferring torque from the transmission output directly to the ground. As a critical load-bearing element, it ensures precise alignment of the drivetrain under extreme stress. The SKU 2093.094.002 is a direct replacement part designed to restore factory-spec performance in heavy-duty ZF transmissions.

Symptoms of Failure

• Oil leaks at the axle seal interface: A worn or damaged rear axle often causes hydraulic fluid to seep past the seal, leaving visible puddles under the machine and reducing lubrication efficiency.
• Excessive driveline vibration during acceleration: When the axle shaft develops fatigue or micro-cracks, it produces a rhythmic shudder that intensifies under load, a common sign of imminent failure.
• Intermittent gear slipping or clunking noises: A failing rear axle can cause misalignment within the differential, leading to sudden torque loss or metallic grinding sounds during turns.
• Uneven tire wear or tracking issues: Structural deformation of the axle housing forces the wheels out of alignment, accelerating tread wear on one side of the vehicle.

Technical Specifications

Compatibility

This rear axle is designed for integration with ZF’s heavy-duty transmission series commonly found in wheel loaders, graders, and dump trucks. It is a direct fit for the WG180, WG200, and WG211 transmission models. It also interfaces with the ZF 4WG-200 and ZF 6WG-250 series, where it mounts between the differential housing and the final drive assembly. Always verify the spline count and axle length against your specific machine’s service manual before installation.

Related Components

During a rear axle replacement, it is strongly recommended to inspect and replace the following companion parts that share the same assembly. The 2093109022: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING are critical for maintaining proper preload. Additionally, the 2093209096: DIFFERENTIAL and the 2093309073: DIFF.HOUSING must be checked for wear to prevent premature axle failure.

Frequently Asked Questions

Q: Can the ZF 2093.094.002 rear axle be used in a ZF 4WG-200 transmission?
A: Yes, this axle is fully compatible with the ZF 4WG-200 series. However, you must verify the spline count and overall length against your specific machine’s original part to ensure a proper fit.

Q: What are the first signs that this rear axle needs replacement?
A: The earliest indicators are oil seepage around the axle seal and a low-frequency humming noise that increases with vehicle speed. If ignored, these symptoms escalate into vibration and gear clunking.

Q: Do I need to replace the taper roller bearing at the same time?
A: Yes, it is highly recommended. The 0750117075: TAPER ROLLER BEARING is directly preloaded against the axle shaft. Reusing an old bearing with a new axle often leads to premature failure due to mismatched wear patterns.
