ZF 5838.300.816 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 5838.300.816 REAR AXLE HOUS. is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part encases the differential and axle shafts, providing the rigid support necessary to transfer torque from the transmission to the wheels. As the primary load-bearing shell, it maintains precise gear alignment under extreme stress. The SKU 5838.300.816 is engineered to ZF’s exacting tolerances, ensuring a direct fit without modification. It works in concert with the 5838109021: DIFFERENTIAL to distribute power evenly, while the 0750117075: TAPER ROLLER BEARING supports rotational loads within the housing cavity.

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.
• Abnormal whining or grinding noises: When the housing loses its structural integrity, the 2095209019: DIFFERENTIAL can shift out of alignment, causing metal-on-metal contact.
• Vibration during low-speed turns: A deformed housing prevents the 0631329086: SPRING PIN from locking components securely, leading to driveline shudder.
• Premature bearing wear: Misalignment forces the taper roller bearings to operate at incorrect angles, accelerating failure.

Technical Specifications

Compatibility

This rear axle housing is designed for ZF’s heavy-duty powershift transmission series commonly used in wheel loaders and graders. It is a direct fit for the WG180 and WG200 transmission models. It also integrates with the WG150 series when paired with specific differential carriers. Always verify the housing casting number against your machine’s serial plate before ordering.
