Overview
The ZF 2093.117.044 REAR AXLE HOUS. is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part encases the differential gears, bearings, and axle shafts, providing the rigid support necessary to transfer torque from the transmission to the wheels. The SKU 2093.117.044 is precision-machined to maintain exact gear alignment under extreme loads, ensuring that power delivery remains smooth and consistent during demanding operations such as earthmoving and material handling.
Symptoms of Failure
- Oil leaks around the axle housing seals: When the housing cracks or its mating surfaces warp, transmission fluid seeps out, leading to low lubricant levels and accelerated internal wear.
- Whining or grinding noise from the rear axle: A worn housing can misalign the 2093109029: DIFFERENTIAL and 0750117075: TAPER ROLLER BEARING, producing metallic sounds during turns or acceleration.
- Vibration during low-speed operation: A distorted housing causes uneven load distribution on the 2093209094: DIFFERENTIAL and 2093309078: DIFF.HOUSING, resulting in noticeable chassis shudder.
- Difficulty engaging or disengaging the differential lock: Structural fatigue in the housing can bind the internal shift mechanism, making gear changes erratic.

Frequently Asked Questions
Q: Can I reuse the old bolts when installing the 2093.117.044 housing?
A: No. ZF recommends replacing all fasteners with new OEM bolts to achieve the correct clamping force and prevent stress fractures in the housing flange.
Q: How do I know if my housing is warped without measuring tools?
A: Place a straightedge across the mating surface. If you can slide a 0.05 mm feeler gauge under any point, the housing is out of spec and should be replaced.
Q: Does this part include the differential carrier bearings?
A: No. The housing is supplied as a bare casting. You must order the 0750117075: TAPER ROLLER BEARING and 0730300820: THRUST WASHER separately for a complete rebuild.
