ZF 2093.117.022 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2093.117.022 REAR AXLE HOUSING is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part encases the differential and axle shafts, providing the rigid support necessary to transfer torque from the transmission to the wheels while withstanding extreme loads and shock from rough terrain. The SKU 2093.117.022 serves as the central mounting point for the entire rear axle system, ensuring precise alignment of internal gears and bearings. Without this housing, the drivetrain cannot maintain proper gear mesh, leading to rapid component wear or catastrophic failure.

Symptoms of Failure

• Oil Leaks from Axle Seals: Cracks or warping in the housing cause lubricant to escape, leading to low oil levels and eventual gear damage. Search for “ZF rear axle housing oil leak repair.”
• Abnormal Gear Noise or Howling: A worn housing allows misalignment of the differential, producing a distinct whining or grinding sound during turns. This is a common symptom of “axle housing bearing bore wear.”
• Vibration During Operation: Structural fatigue in the housing leads to excessive vibration felt through the chassis, often accompanied by “rear axle housing stress fracture symptoms.”
• Uneven Tire Wear: A deformed housing alters the wheel alignment, causing rapid, irregular tire wear patterns that signal the need for a housing replacement.

Technical Specifications

Compatibility

This rear axle housing is designed for ZF’s heavy-duty powershift transmission series commonly used in construction equipment. It is a direct fit for the ZF WG180 and ZF WG200 transmission models, which are found in wheel loaders, graders, and telehandlers. The housing also supports the ZF WG150 series in certain configurations. For precise fitment, always verify the transmission model and axle ratio before ordering.

During installation, this housing works in conjunction with the 2093109021: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING to ensure smooth rotation. The 2093209096: DIFFERENTIAL and 2093309073: DIFF.HOUSING are also mounted directly within this assembly.

Frequently Asked Questions

Q: Can I install the ZF 2093.117.022 housing without replacing the bearings?
A: It is strongly recommended to replace the 0750117075: TAPER ROLLER BEARING whenever the housing is swapped, as bearing seats can wear unevenly and cause premature failure.

Q: What causes cracks in this rear axle housing?
A: Common causes include overloading the machine beyond its rated capacity, repeated impact loads from rough terrain, or fatigue from long-term use without proper lubrication maintenance.

Q: Is the 2093.117.022 compatible with the ZF WG150 transmission?
A: Yes, it is compatible with the WG150 series in most configurations, but you should verify the axle ratio and mounting bolt pattern to ensure a perfect fit.
