Product Introduction 30J-01031 Steering Knuckle Side Pin is the pivotal rotating shaft on EQ153 commercial vehicle front axle steering knuckle assembly. It bears the front axle load and acts as rotation center for knuckle, enabling wheels to swing smoothly for steering adjustment. This aftermarket replacement pin addresses stiff steering response, excessive axial clearance and continuous knocking noise over rough roads, which stemmed from surface scoring, thread wear and metal fatigue of old pins. It stabilizes steering feedback and reduces abnormal tire wear for heavy-duty regional freight and long haul transport vehicles.
Product Advantages Crafted from forged alloy steel with quenching and tempering treatment for excellent load resistance. Precision ground outer surface maintains smooth fit with matching bushing set. Anti-rust surface coating resists erosion from muddy, saline and humid road conditions. Each pin is strictly checked for dimensional tolerance before delivery, consistent hardness and convenient for front axle overhaul work.
