ZF 2099.117.033 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2099.117.033 REAR AXLE HOUSING is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part encloses the differential and axle shafts, providing the rigid support necessary to transfer torque from the transmission to the wheels. As the primary load-bearing casing, the housing maintains precise gear alignment under extreme stress. The SKU 2099.117.033 is engineered to ZF’s exacting tolerances, ensuring a perfect seal against contaminants and preventing lubricant loss in demanding environments such as excavators and wheel loaders.

Symptoms of Failure

• Visible oil seepage from axle seals: A cracked or warped housing often leads to lubricant escaping past the seals, leaving puddles under the machine and risking gear damage.
• Unusual whining or grinding noises during turns: When the housing distorts, the 2099109013: DIFFERENTIAL and 2093209094: DIFFERENTIAL components lose proper mesh, creating audible metal-on-metal contact.
• Excessive backlash in the drivetrain: A fatigued housing allows the 0750117075: TAPER ROLLER BEARING seats to shift, causing noticeable play in the rear wheels during acceleration or deceleration.
• Vibration at low speeds: Structural cracks in the 2093309078: DIFF.HOUSING area transmit irregular forces through the axle, felt as chassis shudder.

Technical Specifications

Compatibility

This rear axle housing is designed for ZF’s WG series powershift transmissions commonly used in construction machinery. It directly fits the WG180 and WG200 transmission models, which are found in articulated dump trucks and graders. It is also compatible with the WG160 series in certain loader configurations. Always verify the housing casting number against your existing unit before installation, as variations exist for different axle ratios.
