ZF 2093.093.015 REAR AXLE | OEM Genuine Part

Overview

The ZF 2093.093.015 REAR AXLE is a critical load-bearing and torque-transferring component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part sits at the output end of the transmission, directly connecting the differential housing to the wheel hubs. Designed to withstand extreme torsional stress and heavy radial loads, the 2093.093.015 ensures that power from the gearbox is efficiently transmitted to the wheels for reliable machine propulsion. When rebuilding a ZF axle assembly, this rear axle shaft must be inspected alongside the 2093109013: DIFFERENTIAL and the 2093209096: DIFFERENTIAL to ensure proper gear mesh and alignment.

Symptoms of Failure

• Oil leaks at the wheel end seal: A worn rear axle shaft often damages the oil seal contact surface, causing gear oil to weep from the hub. This is a common “ZF rear axle oil leak” issue.
• Excessive end-play or wheel wobble: When the axle splines or bearing journals wear, the wheel develops noticeable lateral movement, especially under load. This symptom is frequently reported as “loose rear axle on ZF transmission.”
• Metallic grinding noise during turns: A damaged rear axle can cause misalignment with the differential gears, producing a distinct grinding sound when the machine turns. This is often searched as “ZF axle grinding noise when turning.”
• Vibration during high-speed travel: Worn axle shafts create rotational imbalance, leading to severe driveline vibration that worsens with speed.

Technical Specifications

Compatibility

This rear axle is engineered for ZF heavy-duty powershift transmissions commonly used in construction machinery. Based on its design and spline configuration, the 2093.093.015 is compatible with the following ZF transmission models: WG180, WG200, WG210, and WG250 series. It is also found in certain APL-300 and APL-400 final drive assemblies. Always verify the axle length and bearing seat dimensions against your specific machine’s service manual. For a complete rebuild, pair this axle with the 2093109013: DIFFERENTIAL and the 2093209096: DIFFERENTIAL to guarantee proper backlash and gear pattern.

Frequently Asked Questions

Q: Can I use the 2093.093.015 rear axle in a ZF WG180 transmission?
A: Yes, this axle is designed for WG180, WG200, and WG210 series transmissions. However, always confirm the spline count and overall length match your specific application before installation.

Q: What torque should I apply to the axle nut when installing this part?
A: The recommended tightening torque for the axle retaining nut is typically 450-550 Nm, depending on the bearing preload specification. Always refer to the ZF service manual for your exact model.

Q: Is it necessary to replace the taper roller bearing when installing a new rear axle?
A: Yes, it is strongly recommended to install a new 0750117075: TAPER ROLLER BEARING whenever the axle is replaced. The bearing race and roller condition directly affect axle alignment and seal life.
