ZF 2099.117.014 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2099.117.014 REAR AXLE HOUSING is a critical structural component within the final drive assembly of heavy-duty construction machinery transmissions. This OEM genuine part serves as the rigid casing that encloses and supports the differential gears, axle shafts, and bearing sets, ensuring precise alignment under extreme torque loads. Designed to withstand high-impact stress from off-road applications, the housing maintains proper gear mesh and lubricant containment. The SKU 2099.117.014 is engineered to exact ZF tolerances, making it a direct replacement for worn or cracked housings in loader and grader drivetrains.

Symptoms of Failure

• Rear axle oil leaks around the housing seam: Cracks or porosity in the casting cause gear oil to weep onto brake components, leading to reduced braking efficiency and fluid loss.
• Abnormal gear whine or grinding from the differential area: A warped or fatigued housing misaligns the 2099109004: DIFFERENTIAL, creating uneven tooth contact and audible distress during turns.
• Excessive backlash or clunking on acceleration/deceleration: Bearing bore wear within the housing allows the 0750117075: TAPER ROLLER BEARING to shift, resulting in driveline lash and vibration.
• Contaminated lubricant with metallic debris: Internal fractures shed casting particles into the oil, accelerating wear on the 2093209095: DIFFERENTIAL and 2093309071: DIFF.HOUSING.

Technical Specifications

Compatibility

This rear axle housing is designed for ZF WG-series powershift transmissions commonly found in construction machinery. It is a direct fit for the WG180 and WG200 transmission models, as well as the heavy-duty WG310 series used in wheel loaders and dozers. The housing also integrates with select ZF 4WG-200 and 5WG-210 drivelines. Always verify axle flange bolt patterns and differential carrier dimensions before installation.
