Overview
The ZF 2093.117.016 REAR AXLE HOUSING is a structural core component within heavy-duty construction machinery drivetrains. This OEM genuine part encases the differential assembly and final drive gears, providing the rigid mounting point for axle shafts and bearings. As the primary load-bearing shell, it maintains precise gear alignment under extreme torque loads. The SKU 2093.117.016 is engineered to withstand high stress from rough terrain and heavy payloads, ensuring the rear axle assembly remains sealed against contaminants.
Symptoms of Failure
- Visible oil seepage from axle housing seams: Cracks or porosity in the 2093.117.016 casting cause lubricant loss, leading to differential overheating. Search “ZF rear axle housing oil leak repair” for guidance.
- Abnormal whining or grinding during turns: A warped housing misaligns the 2093109003: DIFFERENTIAL gears, creating metal-on-metal contact.
- Excessive axle shaft play: Worn bearing seats in the housing allow the 0750117075: TAPER ROLLER BEARING to shift, causing vibration at highway speeds.
- Metal debris in differential fluid: Internal fractures shed particles from the housing bore, contaminating the 2093209096: DIFFERENTIAL unit.

Frequently Asked Questions
Q: Can the 2093.117.016 housing be welded if cracked?
A: Welding is not recommended. The ductile iron casting requires controlled preheating and post-weld stress relief; replacement with an OEM genuine part ensures structural integrity under load.
Q: What is the torque specification for housing bolts?
A: For the 2093.117.016, flange bolts should be tightened to 280 Nm (207 ft-lbs) using a cross-tightening pattern. Always replace bolts after removal.
Q: Does this part include the axle tubes?
A: No. The 2093.117.016 is the central housing only. Axle tubes are sold separately; pair with the 2097309085: DIFFERENTIAL AXLE for complete assembly.
