Product Introduction
The steering knuckle (HOWO L 199112410057) is a key component of the truck front axle steering system. It connects the wheel hub, brake assembly, and suspension linkage, allowing the wheel to rotate while maintaining stable load support and precise steering control.
This knuckle is made from high-strength forged steel, designed to withstand heavy impact loads, road vibration, and continuous steering stress under full-load conditions. It works together with the kingpin, hub bearing, and tie rod system to ensure smooth and stable steering performance.
It is widely used in SINOTRUK HOWO heavy-duty trucks, especially in mining, construction, and long-distance transport vehicles where durability and steering reliability are critical.
Each unit is manufactured according to OEM standards and undergoes machining precision checks, load testing, and crack inspection to ensure structural strength and long service life.
