Overview
The ZF 2093.117.023 REAR AXLE HOUS. is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part serves as the rigid casing that encloses and supports the differential gears, axle shafts, and bearing sets, ensuring precise alignment under extreme torque loads. The SKU 2093.117.023 is specifically engineered to withstand the high stress and vibration common in earthmoving equipment, providing a sealed environment that protects internal lubricants from contamination. As the backbone of the rear axle system, this housing directly influences the durability and operational stability of the entire drivetrain.
Symptoms of Failure
- Persistent oil seepage around the axle flange: When the housing develops micro-fractures or the mounting surface warps, lubricant escapes, leading to low oil levels and potential gear damage.
- Abnormal whining or grinding noises from the rear axle: A cracked or distorted housing allows misalignment of the 2093109023: DIFFERENTIAL, causing metal-on-metal contact during operation.
- Increased backlash in the driveline: Worn bearing seats within the housing cause excessive play, resulting in delayed power delivery and harsh engagement when shifting.
- Visible cracks or impact damage near the axle tube: Structural fatigue compromises the housing’s ability to retain the 0750117075: TAPER ROLLER BEARING, leading to sudden wheel lockup or vibration.

Frequently Asked Questions
Q: Can the 2093.117.023 housing be repaired if it has a small crack?
A: Welding is not recommended for this ductile iron housing due to the risk of distorting critical bearing bores. Replacement with a genuine OEM part is the only reliable solution to maintain proper alignment of the 2093109023: DIFFERENTIAL.
Q: How do I know if this housing fits my ZF WG200 transmission?
A: The 2093.117.023 is a direct fit for WG180, WG200, and WG210 models. However, you must also check the compatibility of the 0750117075: TAPER ROLLER BEARING and the 2093209096: DIFFERENTIAL to ensure the entire assembly matches your axle ratio.
Q: What is the typical lifespan of this rear axle housing under normal operating conditions?
A: With proper lubrication and no impact damage, the housing can last the entire life of the machine (10,000+ hours). Regular inspection of the 2093309073: DIFF.HOUSING for signs of corrosion or stress is advised to prevent premature failure.
