ZF 2093.073.008 REAR AXLE | OEM Genuine Part

Overview

The ZF 2093.073.008 REAR AXLE is a critical OEM genuine component engineered for the demanding environments of construction machinery. This part serves as the primary structural and rotational hub at the rear of the vehicle, transferring torque from the differential assembly directly to the wheel hubs. It integrates seamlessly with the axle housing and supports the entire drivetrain load during heavy excavation and material handling. The SKU 2093.073.008 is precision-machined to ZF’s exacting tolerances, ensuring long service life in wheel loaders and telehandlers. When paired with a robust 2093109002: DIFFERENTIAL, this rear axle ensures consistent power delivery and minimal backlash under load.

Symptoms of Failure

• Oil leaks near the wheel seal: A worn rear axle often causes gear oil to seep past the hub seal, leaving visible puddles under the machine after shutdown.
• Excessive end-play or wheel wobble: When the axle shaft bearings degrade, operators notice a pronounced wobble in the rear tire during straight-line travel, especially on uneven terrain.
• Grinding noise during turns: A failing axle can produce a metallic grinding sound when the machine articulates, indicating internal spline wear or bearing race damage.
• Reduced traction under load: If the axle shaft twists or fatigues, power delivery to the wheel becomes intermittent, causing the machine to struggle when climbing grades or pushing heavy loads.

Technical Specifications

Compatibility

This OEM genuine rear axle is designed primarily for ZF WG180 and WG200 series transmissions commonly found in mid-size to large construction machinery. It also fits select models in the ZF 4WG-200 and 5WG-200 families. The axle interfaces directly with the differential carrier and requires the correct taper roller bearing set for proper preload. Always verify the spline count and overall length against your existing axle before ordering.

Frequently Asked Questions

Q: Can the ZF 2093.073.008 rear axle be used in a ZF 4WG-180 transmission?
A: Yes, this axle is a direct fit for the WG180 and 4WG-180 series, provided the spline count matches your existing differential. Always cross-reference the axle length and bearing journal diameter before installation.

Q: What is the typical service interval for this rear axle?
A: Under normal construction duty, the axle should be inspected every 1,000 operating hours. Replace the taper roller bearing and seal at the first sign of oil leakage or play to avoid damage to the differential housing.

Q: Does this part come with the bearings and seals included?
A: No, the 2093.073.008 is supplied as a bare axle shaft. You will need to order the 0750117075: TAPER ROLLER BEARING and appropriate seal separately for a complete rebuild.
