ZF 2098.117.013 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2098.117.013 REAR AXLE HOUSING is a structural core component designed to enclose and protect the differential assembly in heavy-duty construction machinery transmissions. This OEM genuine part serves as the rigid mounting point for the axle shafts and final drive gears, ensuring precise alignment under extreme torque loads. The SKU 2098.117.013 is specifically engineered to withstand high-impact stress from off-road applications, providing a sealed environment that prevents contamination of internal lubricants. It integrates directly with the 2098309010: DIFFERENTIAL HOUSING to form the complete axle casing assembly.

Symptoms of Failure

• Hydraulic oil seepage at axle seals: Cracks or porosity in the housing casting often cause slow, persistent oil leaks around the wheel hub interface, leading to low lubricant levels and eventual gear damage.
• Unusual whining or grinding noises during turns: A warped or cracked housing misaligns the 2098109042: DIFFERENTIAL and 2098309011: CROWN WHEEL, producing metallic grinding sounds that worsen under load.
• Vibration in the driveline under acceleration: Structural fatigue in the housing allows the 2099209001: DIFFERENTIAL to shift position, causing driveline shudder and uneven tire wear.
• Contaminated gear oil with metal particles: Internal fractures shed casting debris into the lubricant, accelerating wear on the bevel gears and bearings.

Technical Specifications

Compatibility

This rear axle housing is engineered for ZF WG-series powershift transmissions commonly found in wheel loaders, telehandlers, and graders. It is a direct fit for the WG180, WG200, and WG211 transmission families. The housing also supports the AP400 and AP500 axle series used in medium-duty construction equipment. Always verify the casting number against your existing housing before installation.
