Overview
The ZF 2093.117.029 REAR AXLE HOUSING is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part encloses the differential and axle shafts, providing the rigid support necessary to withstand extreme torque loads during excavation, grading, and material handling operations. As the primary load-bearing shell, it ensures precise alignment of internal gears and bearings, directly influencing drivetrain durability. The SKU 2093.117.029 is engineered to ZF’s original specifications, guaranteeing a direct fit and long service life in demanding environments.
Symptoms of Failure
- Oil leakage from axle housing seals: Cracks or porosity in the housing allow differential oil to seep out, leading to low lubricant levels and potential gear damage. This is often visible as drips under the machine near the wheel hub.
- Unusual whining or grinding noise during turns: A worn or distorted housing can misalign the 2093109029: DIFFERENTIAL and 2093209094: DIFFERENTIAL assemblies, causing metal-on-metal contact and audible distress.
- Excessive play in the rear wheels: Housing fatigue or impact damage allows the 0750117075: TAPER ROLLER BEARING seats to wear, resulting in noticeable wheel wobble and uneven tire wear.
- Contaminated gear oil with metallic particles: Internal fractures shed debris into the lubricant, which can be detected during routine oil analysis and signals imminent housing failure.

Frequently Asked Questions
Q: Can the ZF 2093.117.029 housing be repaired if cracked?
A: Welding is not recommended due to the risk of distorting critical bearing bores. Replacement with this OEM genuine part ensures proper alignment and load capacity.
Q: What is the typical service life of this axle housing?
A: Under normal operating conditions with proper lubrication, the housing can last 8,000–12,000 hours. Impact damage or seal failure will reduce lifespan significantly.
Q: Does this part include the differential carrier or bearings?
A: No, this is the bare housing only. You will need to transfer your existing 2093109029: DIFFERENTIAL and 0750117075: TAPER ROLLER BEARING into the new housing.
