A worn arm can show up as a clunk over bumps, loose-feeling steering or uneven front tire wear, but other worn suspension parts can produce similar symptoms, so find the cause before replacing anything. With the engine off and the car parked, look at the bushings for cracks and the ball joint boot for tears or leaking grease. A shop can test for play.
