The GMC Sierra Steering Knuckle is like a central intersection that suspension, steering, and wheel hub components feed to, giving the front wheels vertical movement over bumps and a smooth way for the driver's turn to pivot. Mounted between control arms or struts and tied to the tie-rod ends, this compact casting named the Steering Knuckle either carries a spindle for freely rolling rear-wheel drive setups or a sealed-bearing hub for powered axles, ensuring that the wheel spins in a steady plane. Over the generations, two main types of Steering Knuckle are seen. Older rear-wheel-drive Sierra trims employ a one-piece unit with an integral spindle, an uncomplicated and robust design but only suitable for non-driven wheels. All four-wheel-drive versions of GMC trucks use the hub type, in which the drive shaft passes through the knuckle and bolts to the hub, delivering power while still allowing steering. Previously, the heavy pickups had their kingpins incorporated in the knuckle body; however, the modern-day Sierra's upper and lower ball joints are applied to make steering lighter. Steering Knuckle replacement is applied to restore correct wheel alignment. Collision damage and deformed stud bores are the leading causes of Steering Knuckle replacement on a GMC pickup, whether it is spindle or hub style.
