Overview
The ZF 2095.056.008 REAR AXLE is a critical OEM genuine component engineered for heavy-duty construction machinery drivelines. This part serves as the primary output hub within the final drive assembly, transferring torque from the differential to the wheel hubs. Designed to withstand extreme torsional loads and harsh operating environments, the SKU 2095.056.008 integrates directly with the axle housing to ensure precise rotational alignment and load distribution. As a genuine ZF part, it guarantees exact fitment and metallurgical integrity, reducing the risk of premature failure in demanding applications such as wheel loaders and graders.
Symptoms of Failure
- Axle shaft oil leaks at the hub seal interface: When the rear axle surface becomes scored or pitted, hydraulic fluid bypasses the seal, leading to visible drips and reduced lubrication efficiency.
- Abnormal gear whine or grinding during turns: Worn splines or bearing journals on the 2095.056.008 cause misalignment with the differential, producing metallic noise under load.
- Excessive backlash in the driveline: A fatigued axle shaft allows rotational play, resulting in a clunking sensation when shifting between forward and reverse.
- Uneven tire wear or vibration at speed: A bent or cracked rear axle disrupts wheel geometry, causing radial runout and accelerated tread degradation.

Compatibility
This rear axle is primarily designed for ZF WG180 and WG200 series power shift transmissions used in mid-size construction machinery. It also fits select WG150 and WG210 variants where the final drive uses a 28-spline differential interface. Always verify axle housing geometry and bearing seat dimensions against your specific transmission model before installation.

When replacing the 2095.056.008, it is recommended to also inspect the 2095109015 DIFFERENTIAL for wear on the side gear bores. The 0750117075 TAPER ROLLER BEARING should be replaced simultaneously to maintain preload. Additionally, verify the condition of the 2095209037 DIFFERENTIAL and the 2095309059 DIFF.HOUSING for cracks or distortion that could compromise the new axle.
