Overview
The ZF 2093.117.019 REAR AXLE HOUS. is a structural core component within heavy-duty construction machinery drivetrains, specifically engineered to encase and protect the differential and final drive gear sets. This OEM genuine part, identified by SKU 2093.117.019, serves as the rigid mounting point for axle shafts and bearings, ensuring precise alignment of rotating assemblies under extreme torque loads. Located at the rear of the transmission assembly, it absorbs significant stress from both the powertrain and the vehicle’s suspension system, making its structural integrity critical for long-term operational reliability.
Symptoms of Failure
- Visible oil seepage from axle housing seals: Cracks or porosity in the housing allow lubricant to escape, leading to low oil levels and accelerated wear on internal components like the 2093109018: DIFFERENTIAL.
- Abnormal whining or grinding noises during turns: A warped or damaged housing misaligns the 0750117075: TAPER ROLLER BEARING, causing uneven gear contact and audible distress.
- Vibration under load or acceleration: Structural fatigue in the housing compromises the mounting stability of the 2093209023: DIFFERENTIAL, leading to driveline shudder.
- Contaminated gear oil with metallic debris: Internal fractures generate metal shavings, often originating from the housing’s bearing journals, which then damage the 5838300626: DIFFERENTIAL HOUSING.

Frequently Asked Questions
Q: Can I reuse the old taper roller bearings when replacing the rear axle housing?
A: No. ZF recommends always installing a new 0750117075: TAPER ROLLER BEARING with a new housing, as bearing raceways conform to the original housing’s bore tolerances.
Q: What is the primary cause of housing cracking in WG200 transmissions?
A: Over-torquing the differential mounting bolts or operating with a worn 5838300626: DIFFERENTIAL HOUSING creates stress risers that propagate cracks.
Q: Does this part require special sealant during installation?
A: Yes. Use ZF-approved anaerobic flange sealant on all mating surfaces to prevent oil bypass and ensure proper alignment of the 2093109018: DIFFERENTIAL.
