F01-3301011
Product Details
1. Basic Overview & Core Functional Positioning
The F01-3301011 Rear Steering Knuckle is a genuine Original Equipment Manufacturer (OEM) component exclusively developed and produced by Chery Automobile Group, specifically tailored for the Chery Jetour X70 mid-size SUV—a model celebrated for its spacious interior, reliable performance, and versatility in both urban commuting and long-distance travel. As a critical core component of the vehicle’s rear suspension and steering system, this rear steering knuckle (hereinafter referred to as "the knuckle") is mounted at the rear wheel hub of the Jetour X70, serving as a vital connecting hub that links the rear suspension assembly (including upper and lower control arms), wheel hub, brake system, and steering linkage. It undertakes multiple irreplaceable core functions that directly affect the vehicle’s driving stability, steering precision, and braking safety, making it an indispensable part of the Jetour X70’s chassis system.
Unlike front steering knuckles that bear more complex steering forces, the F01-3301011 Rear Steering Knuckle is primarily responsible for supporting the vehicle’s rear weight, transmitting vertical, lateral, and longitudinal forces between the rear wheel and the vehicle body, and ensuring the rear wheel maintains the correct geometric position during driving and steering. It works in tandem with the rear suspension components (such as control arms, stabilizer bars, and shock absorbers) to absorb road vibrations and shocks, reducing their transmission to the passenger compartment and enhancing ride comfort. Additionally, the knuckle provides a stable mounting base for the rear brake caliper and rotor, ensuring efficient braking performance by transmitting braking forces evenly to the rear wheel. As a key load-bearing component, it also plays a crucial role in maintaining the Jetour X70’s rear wheel alignment (camber, toe-in, and caster), preventing irregular tire wear and ensuring stable handling, especially during high-speed driving or sharp turns.
The part number F01-3301011 serves as a unique identifier for this rear steering knuckle, distinguishing it from the front steering knuckle (with a different part number) and other components in the Jetour X70’s rear suspension system (such as control arms, bushings, or wheel hubs). It also differentiates the component from rear steering knuckles used in other Chery or Jetour models (such as the Jetour X90, Chery Tiggo 7, or Chery Arrizo 8), which are equipped with different chassis layouts, rear suspension configurations, and wheel hub interfaces. As confirmed by Chery’s official spare parts specifications, this knuckle is paired with the part number F01-3301012 for the opposite rear wheel, forming a complete set for the Jetour X70’s rear axle. As a genuine OEM component, it strictly complies with Chery’s original design standards, material requirements, and performance specifications, while also adhering to international automotive quality and safety standards (ISO 9001, IATF 16949) and national automotive safety standards (GB 19752-2021). Every dimension, mounting interface, and structural detail is precision-engineered to perfectly match the Jetour X70’s rear chassis, ensuring seamless integration and optimal compatibility. Unlike low-quality aftermarket rear steering knuckles that often suffer from premature wear, structural deformation, or poor dimensional accuracy, the genuine F01-3301011 Rear Steering Knuckle undergoes rigorous testing and validation to ensure reliability, durability, and stable performance, making it the preferred choice for Jetour X70 owners and professional automotive repair technicians.
2. Premium Material Selection & Precision Manufacturing Process
The Chery Jetour X70 F01-3301011 Rear Steering Knuckle is crafted from high-performance, automotive-grade materials, carefully selected by Chery’s engineering team to withstand the harsh operating conditions of the vehicle’s undercarriage—including exposure to extreme temperatures (ranging from -40°C to 120°C), road salt, moisture, dust, gravel impact, and continuous mechanical stress from vehicle weight and road vibrations. Drawing on advanced automotive component material technology, the team prioritizes materials that balance high strength, impact resistance, wear resistance, and corrosion resistance, ensuring the knuckle maintains stable performance over a service life of typically 120,000–180,000 kilometers under normal operating conditions (depending on usage environment and maintenance habits).
The core structure of the F01-3301011 Rear Steering Knuckle is made of high-strength 6061-T6 aluminum alloy, a premium automotive-grade material widely used in modern suspension components due to its excellent mechanical properties and lightweight advantages. This aluminum alloy variant offers superior tensile strength (minimum 310 MPa) and yield strength (minimum 276 MPa), ensuring it can withstand the high load-bearing forces and impact forces exerted during driving, braking, and steering. It also exhibits exceptional impact resistance, allowing the knuckle to absorb and dissipate impact energy from uneven road surfaces without cracking or permanent deformation. Additionally, 6061-T6 aluminum alloy is lightweight, reducing the unsprung mass of the rear suspension by 25–30% compared to traditional steel knuckles—which improves suspension response speed, reduces fuel consumption, and enhances overall vehicle handling. The material also has good corrosion resistance, preventing rust and degradation caused by road salt, moisture, and environmental pollutants, which is critical for long-term durability in harsh undercarriage environments.
Consistent with advanced rear steering knuckle design, the F01-3301011 incorporates precision-engineered bushings for connection with suspension arms, where the bushing structure includes an outer tube, inner tube, and rubber filling layer to enhance assembly precision and vibration damping performance. The outer surface of the knuckle is treated with a multi-layer anti-corrosion coating process to further enhance its durability. First, the knuckle undergoes a zinc phosphate treatment to form a protective layer that prevents corrosion at the material surface. It is then coated with an electrostatic spraying anti-rust primer and a topcoat, which not only provides additional corrosion protection but also ensures the knuckle’s surface matches the Jetour X70’s chassis aesthetic. The coating is resistant to scratches, fading, and peeling, ensuring long-term protection even in harsh environments such as coastal areas or regions with severe winters.
The manufacturing process of the F01-3301011 Rear Steering Knuckle follows a strict, ISO 9001 and IATF 16949 certified production workflow, consistent with Chery’s global quality standards and advanced precision manufacturing practices. As optimal for complex structural components, the knuckle is produced via high-precision aluminum alloy casting, using advanced die-casting technology to ensure uniform material density and structural integrity, eliminating internal defects such as bubbles or cracks that could compromise load-bearing capacity. After casting, the knuckle undergoes a series of post-processing steps, including precision machining, deburring, and heat treatment (T6 tempering), which further enhance the material’s strength, hardness, and dimensional stability. The mounting holes for the suspension arms, wheel hub, and brake caliper are precision-machined using CNC machining centers, ensuring dimensional accuracy with a tolerance of ±0.02 mm—critical for proper fitment with other rear suspension components and ensuring precise wheel alignment.
The entire assembly undergoes rigorous quality control testing, including dimensional accuracy testing, tensile strength testing, impact resistance testing, corrosion resistance testing, and fatigue testing. The fatigue testing ensures the knuckle can withstand over 2 million cycles of mechanical stress without failure, meeting Chery’s strict durability requirements and ISO 16750 fatigue standards. Additionally, the knuckle’s bushing assembly is tested for press-fit accuracy and vibration damping performance, ensuring the connection with suspension arms is secure and stable. Only rear steering knuckles that pass all these tests are allowed to leave the factory, ensuring the F01-3301011 series delivers reliable, long-lasting performance in the Jetour X70’s rear suspension system.
