ZF 4642.353.008 AXLE for WG150 | OEM Genuine Part

Overview

The ZF 4642.353.008 AXLE is a critical load-bearing component engineered specifically for the WG 150 Series transmission. This OEM genuine part serves as the primary rotational support within the planetary gear set, ensuring precise alignment of gears and shafts under high-torque conditions. As a hardened steel axle, it absorbs radial and axial forces generated during power shifts, directly influencing drivetrain efficiency. The SKU 4642.353.008 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn units in heavy-duty commercial vehicles and industrial machinery. When installed alongside a robust TRANSMISSION HOUSING (4642101109), this axle maintains the structural integrity required for prolonged service intervals.

Symptoms of Failure

• Persistent oil leaks around the axle seal: A worn 4642.353.008 axle can develop surface scoring, breaking the seal interface and allowing transmission fluid to escape. This often manifests as drips near the bell housing.
• Gear slipping under load: When the axle loses its dimensional stability, gear engagement becomes erratic. Operators may notice a sudden loss of power transfer during acceleration or climbing.
• Abnormal whining or grinding noises: Bearing surfaces on a fatigued axle produce a high-pitched whine that escalates to a grinding sound as metal-on-metal contact occurs, particularly in lower gears.
• Vibration in the driveline: A bent or cracked axle creates harmonic vibrations felt through the chassis, worsening as vehicle speed increases.

Technical Specifications

Compatibility

This axle is primarily designed for the ZF WG 150 Series transmission, but its dimensions and spline profile also suit the WG 180 and WG 200 models used in medium-duty trucks and construction loaders. It is not compatible with the WG 120 series due to differing shaft diameters. For proper installation, always pair this axle with a matching TRANSMISSION HOUSING (4642301205) to ensure correct bearing preload. The assembly also requires a TYPE PLATE (0730365125) for accurate identification, and the axle is secured using a GROOVED STUD (0631311009) to prevent rotational loosening.
