The steering knuckle ass is a complete pivot assembly for HOWO 4X2 tractor trucks. This essential steering component includes the Upper bushing and the Lower bushing, which work together to provide smooth, precise wheel movement.
The steering knuckle ass connects the wheel hub to the front axle beam, enabling accurate steering while maintaining proper geometry. When you choose authentic howo Parts, you receive a steering knuckle ass that meets all OEM specifications for durability and performance.
This steering knuckle ass is engineered to withstand heavy loads, rough terrain, and continuous operation. Its robust design ensures long service life and consistent steering feedback, making it a trusted choice for fleet operators worldwide.
The steering knuckle ass is a direct replacement for worn or damaged units, restoring factory-fresh steering feel and extending the life of your steering system.
The Upper bushing is a precision-machined bronze or steel sleeve that fits into the upper bore of the steering knuckle ass. It provides a low-friction bearing surface for the kingpin, reducing wear and ensuring smooth rotation of the knuckle around the vertical axis.
This Upper bushing is designed to handle the radial loads transmitted from the wheel during cornering and braking. Its split design allows for easy installation and removal, simplifying maintenance. The internal surface is oil-grooved to retain lubricant, minimizing friction and extending the service interval of the steering knuckle ass.
Manufactured from high-quality bronze alloy, the Upper bushing offers excellent wear resistance and conformability. Its precise dimensional tolerances ensure a perfect fit with the kingpin, eliminating play and ensuring accurate steering response. This bushing is a critical component of the steering knuckle ass, directly affecting handling and tire wear.
The Lower bushing is the counterpart to the Upper bushing, positioned in the lower bore of the steering knuckle ass. Together with the upper bushing, it supports the kingpin and ensures stable, friction-free rotation of the steering knuckle.
This Lower bushing is constructed from the same durable bronze material and features identical internal lubrication grooves. Its robust construction withstands the higher thrust loads experienced at the lower end of the kingpin, where forces from the road surface are most intense.
Proper functioning of the Lower bushing is essential for maintaining correct caster and camber angles. Any wear in this bushing will result in steering wander and premature tire wear. The steering knuckle ass includes both bushings as matched pairs, ensuring consistent performance and easy replacement.

The steering knuckle ass uses high-grade bronze bushings that are self-lubricating and highly resistant to wear. This ensures long-lasting performance and reduces the frequency of replacements, saving you time and money.
Every steering knuckle ass is manufactured to exact OEM dimensions, guaranteeing a perfect fit with the kingpin and axle beam. This eliminates play and ensures smooth, accurate steering response from the moment of installation.
The steering knuckle ass includes both the upper and lower bushings, along with all necessary seals and hardware. This all-in-one approach simplifies ordering and ensures you have everything needed for a quick, hassle-free replacement.
Used by fleet operators across the globe, this steering knuckle ass has been tested in extreme climates and road conditions. Its robust construction delivers consistent performance, keeping your HOWO 4X2 on the road and productive.
The steering knuckle ass is the result of extensive engineering and testing to meet the demanding requirements of heavy-duty trucking. Its forged steel body provides exceptional strength, while the precision-ground bushing bores ensure accurate alignment of the upper and lower bushings.
The design of the steering knuckle ass focuses on reducing friction and heat generation. The internal oil grooves in both bushings allow lubricant to spread evenly across the bearing surfaces, minimizing wear even during prolonged operation. This attention to detail extends the service life of the entire steering pivot system.
Additionally, the steering knuckle ass is manufactured with a protective coating that resists corrosion from road salt, moisture, and chemicals. This ensures that the bushings and the knuckle body remain in good condition, even in harsh environments, reducing the risk of seizure or premature failure.
Every steering knuckle ass undergoes rigorous quality control inspections. The bushing dimensions are verified using high-precision gauges to ensure they fall within the strict tolerance band. The assembly is also checked for proper fitment with standard kingpin sizes.
We perform random destructive testing on samples from each production batch, including press-out tests to measure bushing retention and fatigue tests to simulate thousands of steering cycles. These tests confirm that the steering knuckle ass meets or exceeds original equipment standards, giving you confidence in its durability.
Our commitment to quality is backed by years of experience supplying steering components for HOWO vehicles. We have continuously refined our manufacturing processes to eliminate common failure points such as bushing loosening, galling, and premature wear, resulting in a steering knuckle ass that performs reliably over the long haul.
Investing in a genuine steering knuckle ass reduces long-term maintenance costs. The high-quality bushings require less frequent replacement compared to lower-grade alternatives, and the extended service intervals mean less downtime for your fleet.
For fleet managers, the steering knuckle ass simplifies inventory management because it is a single part number that includes both bushings. This reduces the risk of ordering incorrect components and streamlines the repair process, as workshops always have the complete kit on hand.
The improved steering accuracy provided by this steering knuckle ass also contributes to better fuel efficiency, as correctly aligned wheels reduce rolling resistance. Moreover, even tire wear extends tire life, further lowering operating costs. These cumulative benefits make The part a smart investment for any serious fleet operator.
The steering knuckle ass is designed as a drop-in replacement for original equipment. Its dimensions are identical to the factory part, so no modifications to the axle beam or kingpin are required. This ensures that the replacement process is straightforward and can be completed with standard workshop tools.
For maintenance teams, The part offers clear advantages. The bushings are pre-installed in the knuckle, so there is no need to press them in separately, reducing the risk of installation errors. The included lubrication grooves are already filled with high-quality grease, so the assembly is ready to operate immediately after installation.
Furthermore, The part is designed to be compatible with both standard and greaseless kingpin setups. This versatility makes it suitable for a wide range of HOWO 4X2 configurations, simplifying your parts ordering and ensuring that you always have the correct component in stock.
Each steering knuckle ass is shipped with a comprehensive installation guide that includes torque specifications, inspection points, and alignment tips. This documentation helps ensure that the replacement is performed correctly, maximizing the service life of the component.
Our technical support team is available to answer any questions regarding The part, from compatibility checks to troubleshooting steering issues. We also provide online resources, including video tutorials and FAQs, to assist workshops in achieving the best results.
With The part, you are not just purchasing a part – you are gaining access to a comprehensive support system that ensures your vehicle’s steering system operates at peak performance for years to come.
The steering knuckle ass is the definitive solution for maintaining or restoring the steering precision of your HOWO 4X2 tractor. With its high-quality upper and lower bushings, durable forged construction, and proven reliability, this kit ensures safe and predictable handling in all driving conditions. Choose the steering knuckle ass for your fleet and experience the difference that genuine HOWO quality delivers.
