ZF 4644.352.071 AXLE for WG201 | OEM Genuine Part

Overview

The ZF 4644.352.071 AXLE is a critical load-bearing component engineered specifically for the WG 201 Series transmission. This OEM genuine part serves as the central rotating shaft that transmits torque from the gear set to the output flange, ensuring precise power delivery in heavy-duty industrial drivetrains. Manufactured to ZF’s exacting tolerances, the 4644.352.071 axle supports the planetary gear assembly and maintains proper gear alignment under extreme loads. This part is often replaced alongside the 4644101241: TRANSMISSION HOUSING and 4644301365: TRANSMISSION HOUSING during a full rebuild, as housing wear can accelerate axle fatigue.

Symptoms of Failure

• Oil leaks near the axle seal – Worn axle surfaces allow transmission fluid to bypass the 0634801088: SEALING RING, causing visible drips under the vehicle. This is a common long-tail search query for “ZF WG201 axle oil leak repair.”
• Gear slipping under load – A fatigued axle can cause misalignment of the planetary gears, leading to intermittent power loss during acceleration or hill climbing.
• Unusual whining or grinding noises – Excessive play in the axle bearings produces a metallic grinding sound, especially when shifting between forward and reverse gears.
• Vibration in the driveline – A bent or worn 4644.352.071 axle creates rhythmic vibrations that worsen at higher speeds, often misdiagnosed as a driveshaft issue.

Technical Specifications

Compatibility

This axle is designed for the ZF WG 201 Series, but it also fits select models in the WG180 and WG200 families due to shared planetary carrier dimensions. It is a direct replacement for transmissions used in municipal buses, construction loaders, and agricultural tractors. When installing, always pair the axle with a new 0636305019: SCREW PLUG to seal the lubrication port and prevent contamination.
