Overview
The ZF 2093.117.071 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 rigid support and precise alignment for the axle shafts. As the primary load-bearing shell, it absorbs torsional stress and protects internal lubricants from contamination. The SKU 2093.117.071 is engineered to maintain gear mesh accuracy under extreme torque loads, directly influencing the operational lifespan of the entire axle group.
Symptoms of Failure
When the ZF 2093.117.071 housing deteriorates, operators typically encounter these specific failure modes:
- Hypoid gear oil seepage from housing weld seams or casting pores, often visible as dark residue around the axle center section.
- Abnormal whining or clunking during load shifts, caused by housing flex that misaligns the 2093109029: DIFFERENTIAL carrier bearings.
- Contaminated lubricant due to cracks allowing moisture ingress, leading to accelerated wear on the 0750117075: TAPER ROLLER BEARING races.
- Vibration at constant speed from distorted mounting flanges, which compromises the seating of the 2093209094: DIFFERENTIAL side gears.

Frequently Asked Questions
Q: Can the 2093.117.071 housing be repaired if cracked?
A: Welding is not recommended due to the ductile iron metallurgy. Replacement with this OEM genuine part ensures proper heat treatment and dimensional accuracy for bearing preload.
Q: Does this housing include the axle tubes?
A: No. The 2093.117.071 is the central carrier casting only. Axle tubes and the 2097309085: DIFFERENTIAL AXLE shafts are ordered separately.
Q: What torque specification applies to the housing bolts?
A: For the M16 mounting bolts, use 280 Nm with thread locker. Always consult the ZF service manual for the specific transmission model.
