Overview
The ZF 2093.117.025 REAR AXLE HOUS. is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part, identified by SKU 2093.117.025, serves as the rigid casing that encloses the differential gears, axle shafts, and bearings, ensuring precise alignment under extreme torque loads. It directly interfaces with the 2093109024: DIFFERENTIAL and the 2093209095: DIFFERENTIAL to maintain drivetrain integrity during demanding operations.
Symptoms of Failure
- Oil Leaks at the Axle Seals: A cracked or warped housing often causes lubricant to seep past the seals, leading to low oil levels and potential gear damage. Search “ZF rear axle housing oil leak repair” for diagnostics.
- Abnormal Gear Noise Under Load: When the housing loses structural rigidity, the 0750117075: TAPER ROLLER BEARING can misalign, producing a distinct whining or grinding sound during turns or acceleration.
- Vibration During Operation: A compromised housing allows the 2093309071: DIFF.HOUSING to shift, causing persistent driveline vibration that worsens with speed.
- Premature Bearing Wear: Distortion in the housing bore accelerates wear on the taper roller bearings, often requiring early replacement of the entire assembly.

Frequently Asked Questions
Q: Can I install this housing without replacing the taper roller bearings?
A: It is strongly recommended to replace the 0750117075: TAPER ROLLER BEARING simultaneously, as worn bearings can damage the new housing bore and cause premature failure.
Q: How do I verify if this housing fits my ZF WG200 transmission?
A: Check the mounting bolt pattern (12 x M16 on 280 mm PCD) and ensure your differential unit matches the 2093109024: DIFFERENTIAL specifications. The housing is designed for direct bolt-on compatibility.
Q: What is the typical lifespan of this rear axle housing under heavy construction use?
A: With proper lubrication and regular inspection of the 2093309071: DIFF.HOUSING seals, this OEM part typically lasts 8,000–12,000 operating hours before requiring replacement due to fatigue cracking.
