A worn control arm or ball joint can show up as a clunk over bumps, loose steering or uneven tire wear. Those signs alone do not prove this arm is the problem; a worn tie rod end can feel similar. This listing is one arm for the front right, with one per side of the axle, so the front left is a separate part and both are normally replaced together.
