The Steering Drag Link Assembly with OEM number 45440-39206 (also listed as 45440-37092 and 45440-39205) is a verified OEM-grade direct replacement for HINO DUTRO WU300 / WU340 / WU410 and TOYOTA DYNA / TOYOACE XZU300 / XZU304 / XZU404 series commercial trucks.
As a critical component of the steering linkage system, this drag link connects the pitman arm (from the steering gear box) to the steering knuckle, transmitting motion to facilitate accurate wheel alignment with steering input. Manufactured to OEM specifications, this heavy-duty drag link is constructed from solid steel with a net weight of approximately 1.8 kg and an overall length of 705 mm, ensuring stable and responsive steering performance essential for the safe operation of commercial vehicles.
If your steering drag link is failing, you may experience one or more of the following symptoms:
- Loose or Wandering Steering: Vehicle feels unstable and requires constant steering corrections
- Clunking or Knocking Noise: Metallic sounds from the front steering area when turning or going over bumps
- Uneven or Rapid Tire Wear: Premature or irregular tire wear patterns due to compromised steering geometry
- Increased Steering Wheel Play: Noticeable slack or delay in steering response
- Poor Return-to-Center: Steering wheel does not return to center smoothly after completing a turn
- Visible Damage or Corrosion: Bends, cracks, or excessive rust on the drag link body or ends

Replacing a steering drag link is a critical safety procedure. It is strongly recommended to replace the drag link and related steering components in pairs when necessary.
- CRITICAL: This is the Right-Hand Drive (RHD) drag link — verify your vehicle's drive configuration before ordering
- Quantity Required: 1 per vehicle
- Inspect the pitman arm, steering knuckle, and tie rod ends for wear — replace as necessary
- A front-end alignment is required after installation
- Use new castle nuts and cotter pins during installation
- Safety First: Ensure the vehicle is securely supported on jack stands. Never work under a vehicle supported only by a jack
- Inspection: Every 50,000 km / 12 months. Check for steering play, clunking noises, and visible damage
- Replacement: Immediately if failure symptoms appear
- Note: A worn drag link can cause steering looseness, wandering, clunking noises, uneven tire wear, and poor return-to-center. Replacing it restores tight steering feel and helps protect tires and other front-end parts
