ZF 2093.093.019 REAR AXLE | OEM Genuine Part

Overview

The ZF 2093.093.019 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 vertical load. As a precision-machined assembly, the SKU 2093.093.019 ensures exact alignment of internal gears and bearings, directly impacting traction stability and drivetrain efficiency. When paired with a properly functioning 2093109008: DIFFERENTIAL, this rear axle maintains consistent power delivery under extreme operational stresses.

Symptoms of Failure

• Persistent oil seepage from axle seals: When the 2093.093.019 rear axle housing develops micro-cracks or seal wear, you will notice gear oil pooling around the wheel hub or dripping onto brake components, often accompanied by a burnt lubricant smell.
• Rhythmic clunking during low-speed turns: Worn splines or bearing journals on this axle cause a distinct metallic knocking sound that intensifies when maneuvering in tight construction sites, indicating imminent spline stripping.
• Uneven tire wear and vibration at highway speeds: A bent or fatigued rear axle shaft creates lateral runout, leading to scalloped tire tread patterns and a low-frequency vibration felt through the chassis.
• Complete loss of drive to one wheel: Catastrophic failure of the axle shaft results in sudden inability to transfer torque, often preceded by a loud snap and immediate vehicle immobility.

Technical Specifications

Compatibility

This OEM rear axle is engineered for ZF’s heavy-duty transmission families commonly deployed in wheel loaders, graders, and dump trucks. It is a direct fit for the WG180 and WG200 series power-shift transmissions, as well as the WG310 series used in larger articulated haulers. The 2093.093.019 also integrates with select Ecomat 4HP and 6HP drivelines when equipped with planetary final drives. Always verify spline count and overall length against your specific axle housing to ensure proper engagement with the differential side gears.

Frequently Asked Questions

Q: Can the 2093.093.019 rear axle be installed without replacing the taper roller bearings?
A: It is strongly recommended to replace the 0750117075: TAPER ROLLER BEARING simultaneously, as worn bearings will quickly damage the new axle shaft’s bearing journal and cause premature failure.

Q: How do I confirm if this rear axle fits my ZF WG200 transmission?
A: Measure the spline count (24 splines) and the overall shaft length (785 mm). Also verify that your existing 2093309073: DIFF.HOUSING has the correct bore diameter to accept this axle’s bearing seat.

Q: What is the typical service life of this OEM rear axle under heavy construction use?
A: With proper lubrication and regular seal inspections, the 2093.093.019 typically lasts 8,000–12,000 operating hours before spline wear becomes critical, depending on load cycles and maintenance intervals.
