Overview
The ZF 2094.317.013 REAR AXLE HOUS. is a critical structural component designed for heavy-duty construction machinery drivelines. This OEM genuine part encloses the differential and final drive gears, providing the rigid mounting point for axle shafts and bearings. Located at the rear of the transmission assembly, it directly channels torque from the drivetrain to the wheels. The SKU 2094.317.013 is precision-machined to maintain exact gear alignment under extreme loads, ensuring reliable power transfer in demanding environments like excavators and wheel loaders.
Symptoms of Failure
- Oil seepage around axle seals: A cracked or warped rear axle housing often causes differential oil to leak past the seals, leaving visible puddles under parked equipment. This is a common long-tail search query for “ZF rear axle housing oil leak repair.”
- Abnormal gear whine or grinding: When the housing loses its dimensional integrity, gear mesh patterns shift, producing a high-pitched whine during acceleration or deceleration. Operators searching “ZF transmission grinding noise when turning” often find this symptom.
- Wheel bearing play or vibration: A fatigued housing can no longer support bearing preload, leading to lateral wheel movement and chassis vibration at low speeds. This matches queries like “construction machinery rear axle wobble causes.”
- Contaminated transmission fluid: Cracks in the housing allow debris and moisture to enter the differential, turning the oil milky or gritty. This is frequently searched as “ZF axle housing contamination symptoms.”

Compatibility
This rear axle housing is engineered for ZF WG series powershift transmissions commonly used in construction machinery. It is a direct fit for the WG180 and WG200 models, as well as the heavy-duty WG250 series. The housing also integrates with certain 4WG-200 and 5WG-180 variants. Always verify your transmission serial number before ordering.
During installation, this housing mates directly with the 2094101017: TRANSMISSION HOUSING to form the main structural backbone. The 2094301069: HOUSING and 2094298054: HOUSING components attach to the rear axle housing to complete the differential enclosure. A 0636302008: SCREW PLUG seals the fill and drain ports on this assembly.
