Sinotruk HOWO Series Heavy Truck Steering Knuckle

This product is a batch of Sinotruk HOWO series heavy truck steering knuckles (English: Steering Knuckle), commonly known as steering knuckles. It is the core load-bearing and steering component of the front axle steering system of heavy trucks, directly determining wheel support stability, steering accuracy, and driving safety. It is compatible with multiple HOWO series heavy truck models, strictly adhering to original factory standards in research and development. It can directly replace old or damaged original factory parts without additional adaptation or modification, precisely matching the original vehicle dimensions, providing a solid guarantee for the stable and efficient operation of the front axle steering system.

I. OE Number and Product Alias ​​(Precise Correspondence, Original Factory Compatibility)

Core OE Number: Common Core OE The parts, numbered AZ9719410040 and AZ9719410041, correspond to the left and right steering knuckles respectively. The clear and easily identifiable markings facilitate batch identification, selection, procurement, and replacement, effectively avoiding compatibility errors caused by model confusion. This ensures perfect compatibility with the original vehicle's front axle, wheels, steering knuckle arms, and other components, requiring no secondary processing or adjustment; they can be installed directly from the box, significantly improving the efficiency of batch repair and replacement.

Product Alias: Commonly known as "Yangtze Horn," named for its unique shape and structure. It is specifically designed for the front axle steering system of Sinotruk Howo series heavy-duty trucks, serving as the core between the wheel and the front axle.The core connecting hub's quality directly affects wheel support, steering precision, and driving safety. It is mass-produced strictly according to Sinotruk's original technical parameters, ensuring quality completely consistent with original parts, combining adaptability and reliability.

II. Core Functions (Bearing Weight and Steering, Precise Steering)

Connecting Hub, Supporting Steering: As the dedicated connecting hub between the wheels and the front axle, the core hub undertakes the dual functions of wheel support and steering. It stably supports the weight of the wheels while converting the steering force transmitted by the steering knuckle arm into precise wheel deflection, enabling flexible vehicle steering and ensuring that the driver's steering operations are quickly and accurately fed back to the wheels, guaranteeing smooth steering.

" Load-bearing and stress-resistant: Utilizing high-strength materials and precision machining processes, it possesses excellent strength, rigidity, and impact resistance. It can withstand the enormous wheel loads, steering stresses, and road impact stresses under complex conditions such as heavy truck loads, mountain roads, and bumpy surfaces for extended periods. This prevents steering knuckle deformation, cracking, and breakage due to excessive loads and stress concentration, ensuring the structural stability of the front axle system.

Integrated installation and coordinated operation: The integrated installation positions of the wheel hub bearings, brake backing plate, and steering knuckle arm are precisely located, strictly adhering to original factory assembly standards. This ensures precise alignment and tight fit of all related components, guaranteeing coordinated operation of the wheel hub bearings, brake backing plate, and steering knuckle arm, improving the compatibility and reliability of the steering and braking systems.Sex.

Ensuring safety and extending lifespan: Through stable support and precise steering, it reduces uneven stress on the steering system, front axle, and wheel components, avoiding wear and malfunctions caused by component connection deviations, extending the overall service life of the front axle steering system, wheel hubs, and braking system, reducing batch maintenance costs, and adapting to the complex driving needs of heavy-duty trucks for long-distance and heavy-load operations.

III. Product Structure and Material Characteristics (Precision Manufacturing, Durable and Robust)

Excellent Material, Outstanding Strength: Made of high-quality, high-strength ductile iron or forged steel through precision forging, both materials have the characteristics of uniform density, excellent toughness, and high hardness, and undergo strict heat treatment processes (quenching)" (Fire and tempering) further enhances the strength, rigidity, and fatigue resistance of the steering knuckle, enabling it to withstand repeated testing under complex working conditions for extended periods. It is less prone to wear, cracking, and deformation, ensuring load-bearing and steering safety.

Precision forging, meeting accuracy standards: Manufactured in batches through precision forging, CNC machining, grinding, and polishing, the surface is smooth, burr-free, and free of sand holes. Installation points and hole dimensions are precise, with errors controlled within a reasonable range. This ensures a good fit and connection with the wheel hub bearings, brake backing plate, steering knuckle arm, and front axle, eliminating any loosening issues after assembly and guaranteeing smooth steering and reliable braking.

Left and right adaptable, highly versatile: Designed with left and right steering knuckles, each corresponding to a dedicated OE...Numbering, precisely matching multiple Howo models, mass production ensures uniform specifications, can directly replace single or paired damaged original steering knuckles without additional adaptation or modification, easy installation, significantly improving the efficiency of mass repair and replacement, and reducing labor costs.

Corrosion and wear resistant, extended lifespan: The surface undergoes professional anti-corrosion treatment (galvanizing, painting or electrophoresis process) to form a dense protective coating, which can effectively resist the erosion of rainwater, dust, mud, corrosive gases and road salt, preventing the steering knuckle from rusting and corroding, adapting to the complex outdoor driving needs of heavy trucks, greatly extending the product's service life, suitable for mass stockpiling and long-term use.

IV. Compatible Models (Precise matching, no adaptation required) [P

This product is specifically designed for Sinotruk HOWO series heavy-duty trucks, precisely compatible with the following models: Sinotruk HOWO A7, Sinotruk HOWO T7H, HOWO 336, HOWO 371, and other mainstream heavy-duty trucks, covering different years and heavy-duty configurations within this series. The left and right steering knuckles correspond to unique OE numbers, allowing direct connection to the original front axle steering system. It perfectly matches the installation dimensions of all related components, allowing for immediate installation upon opening the box. It provides a convenient and reliable solution for bulk vehicle repair and parts replacement.

Additional notes: This product is individually packaged in bulk to effectively prevent damage such as bumps, scratches, and deformation during transportation and storage; it comes with detailed bulk installation instructions with clear steps.Easy to understand, even those without professional repair experience can efficiently complete the installation by following the instructions. Furthermore, each batch of products undergoes rigorous factory quality testing to ensure that every product meets original factory standards, providing strong support for the safe and stable operation of the heavy-duty truck front axle steering system.
