The steering knuckle is the part of a car's suspension which connects the upper and lower ball joints, tie rods, wheel hub and axle together.
Steering knuckles will rarely go bad in the sense that a lot of parts go bad. More likely are the ball joints wearing out and causing the points of connection to become damaged due to excess play or metal on metal contact. That being said, collisions are also a large contributor to bad steering knuckles.
Replacing a steering knuckle will not only involve the removal of many suspension parts, but also an alignment. We recommend leaving this job to a professional or experienced mechanic.
