ZF 2093.093.004 REAR AXLE | OEM Genuine Part

Overview

The ZF 2093.093.004 REAR AXLE is a critical OEM genuine component engineered for the final drive assembly in heavy-duty construction machinery. This part transmits rotational torque from the differential directly to the wheel hubs, ensuring stable power delivery under extreme loads. As a factory-spec replacement, the SKU 2093.093.004 integrates seamlessly with ZF’s planetary gear sets, providing the structural backbone for the axle housing. When paired with a 2093109005: DIFFERENTIAL, this rear axle maintains precise gear alignment, reducing vibration and extending service intervals in excavators and wheel loaders.

Symptoms of Failure

• Oil leaks near the wheel hub seal: Worn axle shafts allow transmission fluid to escape, leaving visible puddles under the machine. This is a common “ZF rear axle oil leak” search query.
• Intermittent gear slipping under load: When the axle splines wear, you may hear a clunking noise during acceleration, often flagged as “construction machinery axle slipping” in service logs.
• Excessive end-play in the wheel assembly: A failing rear axle causes lateral movement detectable during routine inspections, leading to premature wear on the 0750117075: TAPER ROLLER BEARING.
• Overheating differential housing: Misalignment from a damaged axle forces the 2093209096: DIFFERENTIAL to work harder, generating excess heat that degrades lubricant.

Technical Specifications

Compatibility

This rear axle is designed for ZF WG180, WG200, and WG310 series transmissions commonly used in construction machinery. It directly replaces the axle in models such as the ZF 4WG-180, 4WG-200, and 6WG-310. For optimal performance, always install this axle with a new 2093309073: DIFF.HOUSING to ensure proper bearing preload. The 2093.093.004 also fits select ZF APL-300 series axles used in telescopic handlers.

Frequently Asked Questions

Q: Can the ZF 2093.093.004 be used in a ZF WG180 transmission?
A: Yes, this rear axle is a direct OEM fit for the WG180 series. Ensure you also replace the taper roller bearings and thrust washers to maintain proper preload.

Q: What causes premature failure of this rear axle?
A: The most common cause is contamination from worn seals. Always inspect the differential housing and replace the spring pin (0631100223) during installation to prevent spline wear.

Q: How do I verify the axle spline condition?
A: Measure the spline root diameter with a caliper. If the measurement is below 28.5 mm, the axle has exceeded its service limit and must be replaced immediately to avoid differential damage.
