A clunk over bumps or steering that wanders can mean a worn control arm or ball joint. Worn bushings, tires or alignment can produce similar signs, so with the engine off, look at the front tires for uneven wear and note when the noise happens before you order. A shop can check ball joint play and the arm itself. This listing is a single arm, and both sides are normally replaced together.
