Overview
The ZF 2093.117.005 REAR AXLE HOUS. is a critical structural component engineered to encase and protect the differential assembly and axle shafts within heavy-duty construction machinery transmissions. As an OEM genuine part, this housing provides the rigid mounting point for the final drive gearing, ensuring precise gear alignment under extreme torque loads. The SKU 2093.117.005 sits directly between the transmission output and the wheel hubs, serving as the primary load-bearing shell that maintains lubrication integrity and prevents contamination from debris. When paired with the 2093109002: DIFFERENTIAL, this housing forms the backbone of the rear axle system.
Symptoms of Failure
- Hydraulic oil seepage from axle housing seals: Cracks or porosity in the 2093.117.005 casting often cause slow, persistent oil leaks around the differential mounting flange, leading to low lubricant levels and eventual gear damage.
- Abnormal whining or grinding noise during turns: A warped or fatigued rear axle housing misaligns the 0750117075: TAPER ROLLER BEARING seats, producing metallic grinding sounds that worsen under load.
- Premature bearing or gear wear: Housing distortion causes uneven load distribution across the 2093209095: DIFFERENTIAL assembly, accelerating wear on internal components and reducing service life.
- Vibration through the chassis at operating speeds: A cracked housing fails to dampen driveline oscillations, transmitting harsh vibrations to the vehicle frame during acceleration or deceleration.

Frequently Asked Questions
Q: Can the 2093.117.005 housing be repaired if cracked?
A: Welding is not recommended due to the nodular cast iron composition and risk of distortion. Replacement with an OEM genuine housing ensures proper bearing alignment and seal surface integrity.
Q: What torque specification should be used for the housing bolts?
A: For the M14 flange bolts, tighten to 210 Nm (155 ft-lbs) in a cross-pattern sequence, then apply an additional 90-degree turn. Always use new lock washers.
Q: Does this housing include the differential carrier bearings?
A: No, the housing is supplied as a bare casting. You must install the 0750117075: TAPER ROLLER BEARING and associated shims separately during assembly.
