Overview
The ZF 2093.117.040 REAR AXLE HOUS. is a critical structural component engineered to encase and protect the differential assembly within heavy-duty construction machinery drivelines. This OEM genuine part serves as the rigid backbone for the rear axle system, absorbing torsional loads and maintaining precise gear alignment under extreme operating conditions. The SKU 2093.117.040 is precision-machined to interface directly with the transmission output, ensuring that power is reliably transferred to the wheels. Within the ZF drivetrain hierarchy, this housing sits between the main gearbox and the wheel ends, providing a sealed environment for the 2093109050: DIFFERENTIAL and the 2093209094: DIFFERENTIAL components.
Symptoms of Failure
- Persistent oil seepage from axle seals: A cracked or warped rear axle housing often manifests as hydraulic fluid leaking around the pinion seal or axle tube flanges, leading to low lubricant levels and potential gear damage.
- Unusual whining or grinding noises during turns: When the housing loses structural integrity, the 0750117075: TAPER ROLLER BEARING alignment shifts, producing metallic sounds that intensify under load.
- Vibration through the chassis at low speeds: A distorted housing can cause the 2093309078: DIFF.HOUSING to misalign, transmitting harsh vibrations to the vehicle frame.
- Premature tire wear on one side: Uneven housing geometry alters the wheel track angle, accelerating tread degradation and reducing traction on uneven terrain.

Frequently Asked Questions
Q: Can the ZF 2093.117.040 housing be repaired if cracked?
A: Welding is not recommended due to the ductile iron composition; replacement with this OEM genuine part is the only reliable solution to maintain structural integrity and avoid catastrophic failure.
Q: Does this part include the differential bearings?
A: No, the housing is supplied as a bare casting. You will need to install the 0750117075: TAPER ROLLER BEARING and the 2093109050: DIFFERENTIAL separately during assembly.
Q: What is the expected lifespan of this axle housing in a loader?
A: Under normal operating conditions with proper lubrication, the housing typically lasts 8,000–12,000 hours before fatigue cracks may develop in high-stress zones.
