ZF 2093.093.005 REAR AXLE | OEM Genuine Part

Overview

The ZF 2093.093.005 REAR AXLE is a critical load-bearing and torque-transferring component engineered for heavy-duty construction machinery. This OEM genuine part sits at the final drive stage of the transmission assembly, channeling rotational power from the differential directly to the wheel hubs. Designed to withstand extreme axial and radial loads, the SKU 2093.093.005 ensures precise alignment of the axle shafts, reducing vibration and wear across the drivetrain. It is a direct replacement for failed or worn units in ZF’s modular axle systems, restoring factory-specified clearance and durability.

Symptoms of Failure

• Excessive axle end-play or wheel wobble: When the rear axle wears, lateral movement at the wheel hub becomes noticeable, especially during turning or under load, indicating internal bearing surface degradation.
• Loud grinding or clunking from the axle housing: A failing 2093.093.005 often produces metallic noises during acceleration or deceleration, signaling that the axle shaft has lost its hardened surface integrity.
• Oil seepage at the wheel seal interface: Worn axle journals allow lubricant to bypass the seal, leaving visible wet spots on the brake drum or hub, which can lead to contamination of the brake linings.
• Increased drivetrain vibration at low speeds: A bent or fatigued rear axle causes harmonic imbalances that transmit through the chassis, often misdiagnosed as a tire or bearing issue.

Technical Specifications

Compatibility

This rear axle is designed for integration into ZF’s heavy-duty transmission families, specifically the WG180, WG200, and WG250 series. It also fits select variants of the WG150 and WG300 models used in wheel loaders, graders, and dump trucks. The 2093.093.005 interfaces directly with the 2093109013: DIFFERENTIAL and the 2093209096: DIFFERENTIAL assembly, while being supported by the 2093309073: DIFF.HOUSING. For proper rotational support, it must be paired with the 0750117075: TAPER ROLLER BEARING.

Frequently Asked Questions

Q: Can the ZF 2093.093.005 rear axle be used in a WG180 transmission without modifying the housing?
A: Yes, the 2093.093.005 is a direct OEM fit for the WG180 series. Ensure the corresponding 2093309073: DIFF.HOUSING is not worn at the bearing seat, as this can cause premature failure of the new axle.

Q: What is the typical service life of this rear axle in a wheel loader application?
A: Under normal operating conditions with proper lubrication, the 2093.093.005 can last 8,000–12,000 hours. Frequent shock loads or seal leaks will drastically reduce this lifespan.

Q: Do I need to replace the taper roller bearing when installing a new rear axle?
A: It is strongly recommended. The 0750117075: TAPER ROLLER BEARING wears in a matched pattern with the axle journal; reusing an old bearing can cause misalignment and rapid wear of the new axle shaft.
