Product Introduction

This heavy-duty steering bushing is a critical component of the truck’s steering linkage, designed to absorb vibration, reduce friction, and maintain precise alignment between the steering arm and the chassis. Its robust construction ensures reliable performance under heavy loads and rough road conditions.

Structure & Material

• Material: High-strength steel inner sleeve, bonded to a durable rubber outer layer. The rubber is a synthetic elastomer (typically natural rubber or SBR) with excellent wear resistance and vibration damping properties.

• Design: A cylindrical bushing with a steel core and rubber outer layer. The steel core provides structural rigidity, while the rubber layer absorbs shock and reduces friction during steering movement.

Performance

• Vibration Damping: The rubber layer effectively absorbs road vibrations and shocks, reducing driver fatigue and protecting steering components from damage.

• Low Friction: The precision-machined steel core ensures smooth articulation of the steering arm, minimizing friction and wear.

• Alignment Maintenance: The bushing maintains precise alignment between the steering arm and the chassis, ensuring accurate and responsive steering control.

Core Function

1. Friction Reduction: Provides a low-friction interface for smooth steering arm articulation.

2. Vibration Absorption: Absorbs road shocks and vibrations, protecting steering components and improving ride comfort.

3. Alignment Maintenance: Maintains precise steering geometry for accurate control.

Steering Bush, Bottom WG4071415022 – Sinotruk Sitrak OEM Replacement

When your Sinotruk Sitrak’s steering system starts showing signs of wear, every millisecond of delayed response matters. The Steering Bush, Bottom WG4071415022 is engineered to restore factory-level precision to your front axle steering assembly — reducing friction, eliminating play, and keeping your heavy-duty truck tracking straight under load. Sourced directly from Mettlead’s factory supply chain in China, this bottom steering bush delivers OEM-grade fitment at a price that makes sense for fleet operators and parts distributors worldwide.

Whether you’re managing a logistics fleet across Africa, maintaining construction vehicles in Southeast Asia, or stocking a parts warehouse in the Middle East, this component keeps your Sitrak trucks turning smoothly and safely — mile after mile.

Key Features and Benefits of the WG4071415022 Bottom Steering Bush

This isn’t just a rubber bushing — it’s a precision-machined interface between your steering knuckle and front axle that directly affects driver control and tire longevity. Here’s what sets it apart:

• Friction Reduction: The bush creates a low-friction bearing surface that allows the steering knuckle to pivot smoothly, so drivers experience lighter, more responsive steering input.
• OEM-Exact Dimensions: Manufactured to match the original WG4071415022 specifications, ensuring drop-in installation without modifications or shimming.
• Wear Resistance: Constructed from high-density composite materials designed to withstand the constant rotational stress and heavy axle loads typical of Sitrak heavy-duty applications.
• Extended Service Life: Proper material selection and surface finishing mean fewer replacements over the truck’s operational lifetime — translating directly into lower maintenance costs.
• Front Axle Protection: By absorbing micro-vibrations and distributing load evenly, this steering bush protects the more expensive king pin and steering knuckle assemblies from premature wear.

Application and Vehicle Fitment

The WG4071415022 bottom steering bush is specifically designed for the Sinotruk Sitrak heavy-duty truck platform. It sits at the bottom position of the steering knuckle assembly within the front axle system, where it serves as the primary bearing surface for steering pivot movement.

Its core function is straightforward yet critical: reduce metal-to-metal contact, lower rotational friction, and ensure the steering mechanism operates smoothly — even under full payload conditions. When this bush wears out, drivers typically notice heavier steering effort, uneven tire wear, and a vague feeling in the wheel. Replacing it promptly restores precise directional control and prevents cascading damage to adjacent components.

Frequently Asked Questions

What symptoms indicate the WG4071415022 bottom steering bush needs replacement?

The most common signs include noticeably heavier steering effort (especially at low speeds), a clunking or knocking noise when turning the wheel, uneven front tire wear, and a general looseness or vague feeling in the steering. If you notice any of these, inspecting the bottom steering bush should be your first step — it’s one of the most common wear items in the Sitrak front axle assembly.

Is this steering bush compatible with other Sinotruk models besides Sitrak?

The WG4071415022 is specifically cataloged for the Sinotruk Sitrak platform. While some Sinotruk models share similar front axle architecture, we strongly recommend verifying the OEM part number against your truck’s parts manual before ordering. If you’re unsure, our team can help you cross-reference — just contact us with your VIN or chassis number.

How long does a bottom steering bush typically last on a Sitrak truck?

Service life depends heavily on operating conditions. Under normal highway use with proper greasing intervals, you can expect 80,000–120,000 km. However, trucks operating on rough unpaved roads, carrying consistently heavy loads, or operating in dusty environments may need replacement sooner. Regular inspection during routine front axle service is the best preventive measure.

Does this part require special tools for installation?

Installation typically requires a hydraulic press or bush driver tool to remove the old bush and seat the new one properly. It’s a straightforward job for any workshop familiar with heavy-duty front axle service, but we don’t recommend hammer-fitting — improper installation can damage the bush bore in the steering knuckle and compromise fitment.

Can I order a sample before committing to a bulk purchase?

Absolutely. We encourage new partners to order samples for fitment verification and quality assessment. Sample orders ship quickly, and once you’re satisfied, we can discuss volume pricing and delivery schedules tailored to your restocking cycle.
