WG4071415005 Main Pin (Kingpin) is the core steering axle hinge component for Sinotruk Sitrak heavy‑duty truck. It connects the steering knuckle and front axle, enabling flexible steering of the wheels while bearing huge vehicle load. Long‑time heavy‑load transportation and poor road conditions will lead to pin body wear, gap increase and lubrication failure. Worn main pin will cause loose steering, vehicle pulling to one side and abnormal noise. It is a key replacement spare part for heavy truck front axle steering maintenance.
