Overview
The ZF 5838.073.006 REAR AXLE is a critical OEM genuine component engineered for heavy-duty construction machinery drivelines. This part functions as the primary torque-transferring shaft within the rear axle assembly, connecting the differential output to the wheel hubs. Designed to withstand extreme torsional loads and shock impacts common in earthmoving and material handling equipment, the 5838.073.006 ensures precise power distribution and long-term durability. It sits directly between the differential housing and the axle bevel gear, forming the backbone of the final drive system. When paired with a 5838109009: DIFFERENTIAL and the 5838300626: DIFFERENTIAL HOUSING, this rear axle delivers reliable performance under continuous high-stress operation.
Symptoms of Failure
- Excessive driveline vibration during acceleration: A worn or bent rear axle causes harmonic imbalances that transmit through the chassis, often mistaken for tire issues.
- Oil seepage at the axle seal interface: Fatigue cracks or surface wear on the 5838.073.006 shaft allow gear oil to escape, leaving visible residue near the hub.
- Intermittent wheel lock-up or clunking noises: Spline degradation prevents proper engagement with the differential, leading to sudden torque release and metallic impact sounds.
- Uneven tire wear patterns: A compromised rear axle alters wheel alignment geometry, causing accelerated shoulder wear on drive tires.

Compatibility
This OEM genuine rear axle is designed for ZF WG180, WG200, and WG310 series power-shift transmissions commonly found in wheel loaders, graders, and dump trucks. It also integrates with select ZF TC-Tronic and Ecolite drivelines used in compact construction equipment. For proper installation, always verify the spline profile matches your existing 0750117075: TAPER ROLLER BEARING and 2093209023: DIFFERENTIAL assembly.

Frequently Asked Questions
Q: Can the 5838.073.006 rear axle be used in a ZF WG180 transmission without modifying the differential housing?
A: Yes, this OEM genuine part is a direct replacement for WG180 axles, provided the housing is the 5838300626: DIFFERENTIAL HOUSING. Always inspect spline wear on mating components before installation.
Q: What causes premature failure of the ZF 5838.073.006 rear axle?
A: The most common cause is inadequate lubrication combined with shock loads from repetitive hard braking. Additionally, a worn 0750117075: TAPER ROLLER BEARING can induce misalignment, accelerating shaft fatigue.
Q: How do I verify the 5838.073.006 is the correct axle for my ZF transmission?
A: Measure the spline diameter and count. This part uses 24 involute splines on a 62mm journal. Cross-reference with your existing 5838109009: DIFFERENTIAL to confirm engagement depth.
