ZF 2093.117.058 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2093.117.058 REAR AXLE HOUS. is a structural core component designed to enclose and protect the differential assembly and final drive gears in heavy-duty construction machinery transmissions. This OEM genuine part, identified by SKU 2093.117.058, serves as the rigid mounting point for axle shafts and bearings, ensuring precise gear alignment under extreme torque loads. It sits directly between the transmission output and the wheel hubs, forming the backbone of the rear axle system. When paired with the 2093109063: DIFFERENTIAL, this housing maintains critical clearance tolerances that prevent premature gear wear.

Symptoms of Failure

• Visible oil seepage from axle housing seals: Cracks or porosity in the housing casting allow lubricant to escape, leading to low oil levels and eventual gear damage. Search for “rear axle housing oil leak ZF 2093.117.058” to identify this issue early.
• Abnormal whining or grinding noise during turns: A warped or cracked housing misaligns the 0750117075: TAPER ROLLER BEARING seats, creating metal-on-metal contact. This symptom often appears as “ZF axle housing noise under load” in service reports.
• Uneven tire wear or axle shaft vibration: Structural fatigue in the housing causes the 2093209094: DIFFERENTIAL to shift position, resulting in driveline shudder at highway speeds.
• Metal debris in differential oil: Internal fractures shed casting particles into the lubricant, often mistaken for gear failure. Check for “ZF rear axle housing debris contamination” during routine maintenance.

Technical Specifications

Compatibility

This rear axle housing is engineered for ZF WG-series powershift transmissions commonly used in wheel loaders, graders, and telehandlers. It directly fits the following models: WG180, WG200, WG210, and WG250. The housing also supports retrofit applications on certain ZF 4WG-200 and ZF 6WG-250 drivelines. For proper assembly, always install with a new 0631100223: SPRING PIN to secure the differential lock mechanism, and verify the 0730300820: THRUST WASHER clearance meets factory specifications.

Frequently Asked Questions

Q: Can I reuse the old 2093309078: DIFF.HOUSING gasket when installing this rear axle housing?
A: No. Always replace the housing gasket and all O-rings during installation. The ZF 2093.117.058 housing requires a new seal kit to prevent oil migration between the differential and axle chambers.

Q: How do I verify if my ZF WG200 transmission needs this specific housing?
A: Check the casting number on the existing housing near the oil fill plug. If it matches 2093.117.058, this is the direct OEM replacement. Also inspect the 4482360002: AXLE BEVEL GEAR for wear patterns that indicate housing misalignment.

Q: What torque specification applies to the housing mounting bolts?
A: Tighten all 12 bolts to 280 Nm in a cross-pattern sequence, then apply a final 90-degree angle turn. Use new 0631100223: SPRING PIN inserts to prevent bolt loosening under vibration.
