Overview
The ZF 2095.056.016 REAR AXLE is a critical load-bearing and torque-transferring component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part sits directly between the differential housing and the wheel hub, transmitting rotational force from the axle shafts to the wheels while supporting the vehicle’s static and dynamic weight. As a genuine ZF component, SKU 2095.056.016 ensures precise fitment and metallurgical integrity, which is essential for maintaining the driveline geometry in high-stress environments like excavators and wheel loaders. When paired with a properly functioning 2095109019: DIFFERENTIAL, this rear axle guarantees consistent power delivery and reduces parasitic friction losses.
Symptoms of Failure
- Persistent oil seepage from the hub seal area: A worn rear axle often allows gear oil to migrate past the bearing seats, leaving visible drips on the wheel rim and brake components.
- Low-frequency rumbling during straight-line travel: As the axle shaft surface degrades, it creates a cyclic vibration that intensifies with speed, often mistaken for tire imbalance.
- Intermittent wheel lock-up or dragging sensation: A bent or fatigued rear axle can cause the wheel to bind during turns, particularly when the 0750117075: TAPER ROLLER BEARING loses preload due to axial play.
- Metallic clicking from the hub when reversing: Spline wear on the axle end produces a distinct audible click as the differential gears re-engage, indicating imminent failure of the 2095209037: DIFFERENTIAL interface.

Compatibility
This rear axle is designed for ZF’s WG series powershift transmissions commonly found in mid-size construction equipment. It is a direct fit for the WG180 and WG200 transmission models, which are used in articulated dump trucks, compact loaders, and telehandlers. The axle also integrates with the WG150 series when used with the 2095309059: DIFF.HOUSING adapter kit. Always verify spline count (typically 24 or 28 splines) against your existing assembly before ordering.
