ZF 2093.083.004 REAR AXLE | OEM Genuine Part

Overview

The ZF 2093.083.004 REAR AXLE is a critical load-bearing and torque-transferring component engineered for heavy-duty construction machinery. Positioned at the output of the transmission assembly, this OEM genuine part transmits rotational force from the differential to the wheel hubs, ensuring stable traction under extreme loads. The SKU 2093.083.004 is precision-machined to ZF’s factory tolerances, directly interfacing with the axle housing and final drive system. When installed as part of a complete drivetrain overhaul, this rear axle works in concert with the 2093109001: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING to maintain precise gear alignment and rotational smoothness.

Symptoms of Failure

• Persistent oil seepage at axle seals: Worn splines or a cracked shaft housing allow lubricant to escape, leaving visible puddles under the machine after operation.
• Intermittent gear slipping under load: When the rear axle loses its hardened surface, the splines cannot grip the differential side gears, causing momentary loss of drive power during uphill climbs or heavy digging.
• Abnormal clunking or knocking from the rear housing: Excessive play between the axle shaft and the 2093209095: DIFFERENTIAL creates metallic impact sounds, especially when shifting between forward and reverse.
• Vibration at the wheel end: A bent or fatigued rear axle causes radial runout, leading to uneven tire wear and steering instability at low speeds.

Technical Specifications

Compatibility

This rear axle is designed for ZF’s heavy-duty transmission series commonly found in wheel loaders, graders, and excavators. It is a direct fit for the WG180 and WG200 series power-shift transmissions. Additionally, it is compatible with the ZF 4WG-180, 4WG-200, and 5WG-200 models used in construction machinery from manufacturers such as Liebherr, Caterpillar, and Volvo CE. For proper installation, the axle must be paired with the 2093309071: DIFF.HOUSING to ensure correct bearing preload and seal alignment.

Frequently Asked Questions

Q: Can the ZF 2093.083.004 rear axle be repaired if the splines are worn?
A: In most cases, replacement is recommended. The induction-hardened splines on this OEM part are designed as a single-piece forging; re-splining may compromise structural integrity and lead to premature failure under heavy loads.

Q: What torque specification should be used for the axle flange bolts?
A: ZF specifies a tightening torque of 280 Nm (207 ft-lbs) for the M12 flange bolts, applied in a cross-sequence pattern. Always use new lock washers and refer to the service manual for your specific transmission model.

Q: Is this rear axle compatible with electric-drive construction vehicles?
A: No. The 2093.083.004 is designed exclusively for hydraulic-mechanical ZF transmissions (WG/4WG series). Electric-drive systems require a different axle interface and bearing arrangement.
