Overview
The ZF 2093.117.038 REAR AXLE HOUS. is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part serves as the rigid casing that encloses and supports the differential gears, axle shafts, and bearings, ensuring precise alignment under extreme torque loads. The SKU 2093.117.038 is engineered to withstand high stress from off-road operation, preventing housing flex that can lead to premature gear wear. It sits directly between the transmission output and the wheel hubs, forming the backbone of the rear axle system.
Symptoms of Failure
- Visible oil seepage from axle housing seams: When the housing develops hairline cracks or seal surface corrosion, lubricant escapes, leading to contamination and overheating of internal components.
- Unusual clunking or grinding during turns: A warped or damaged housing misaligns the 2093109029: DIFFERENTIAL gears, causing metallic contact and vibration under load.
- Axle shaft play or wheel wobble: Degraded housing bores fail to properly seat the 0750117075: TAPER ROLLER BEARING, resulting in lateral movement that accelerates tire wear.
- Overheating differential unit: Restricted oil flow from housing distortion prevents proper lubrication of the 2093209094: DIFFERENTIAL assembly, causing thermal damage.

Frequently Asked Questions
Q: Can I reuse the old axle housing if it has minor surface rust?
A: No. Even superficial corrosion can compromise sealing surfaces and cause oil leaks. The ZF 2093.117.038 housing must be replaced if any pitting or scaling is present.
Q: Does this housing require pre-installation machining?
A: No. This is a direct-fit OEM part. However, always inspect the bearing bores and install new 0750117075: TAPER ROLLER BEARING units during replacement to ensure proper clearance.
Q: What is the typical service life of this housing in a wheel loader?
A: Under normal operating conditions, the housing lasts 8,000–10,000 hours. Impact damage from rocks or overloading can drastically reduce lifespan.
