Overview
The ZF 2093.117.006 REAR AXLE HOUSING is a critical structural component engineered to encase and protect the differential assembly within heavy-duty construction machinery transmissions. This OEM genuine part serves as the rigid backbone that supports axle shafts and maintains precise gear alignment under extreme loads. The SKU 2093.117.006 is specifically designed to withstand torsional stress and environmental contaminants, ensuring long-term durability in demanding off-highway applications. When paired with a 2093109003: DIFFERENTIAL, this housing forms the core of the rear axle assembly, distributing power efficiently to the wheels.
Symptoms of Failure
- Visible oil seepage around axle seals: Cracks or warping in the housing allow lubricant to escape, leading to low differential fluid levels and potential gear damage.
- Abnormal whining or grinding noises from the rear axle: A compromised housing can misalign internal components like the 0750117075: TAPER ROLLER BEARING, creating metal-on-metal contact during operation.
- Vibration during acceleration or turning: Structural fatigue in the housing causes the differential carrier to shift, resulting in uneven tire wear and driveline shudder.
- Contaminated gear oil with metallic debris: Internal fractures produce metal shavings that circulate through the lubricant, accelerating wear on the 2093209096: DIFFERENTIAL assembly.

Frequently Asked Questions
Q: Can the ZF 2093.117.006 housing be repaired if cracked?
A: Welding is not recommended due to the ductile iron material properties. Replacement with an OEM genuine housing ensures structural integrity and proper alignment for the differential assembly.
Q: What torque specifications apply to the housing mounting bolts?
A: For the 12 x M16 bolts, tighten to 280 Nm (207 ft-lbs) in a cross-pattern sequence. Always use new lock washers and consult your ZF service manual for exact values.
Q: Does this housing include the axle tubes or seals?
A: No. The 2093.117.006 is supplied as a bare housing casting. You will need to install axle tubes, seals, and the 0750117075: TAPER ROLLER BEARING separately.
