As a pivoting joint, it lets the suspension move through its travel while keeping the wheel located. If a worn ball joint is behind the clunking, looseness or uneven tire wear you're chasing, replacing it helps restore a solid connection.
Inspect the opposite side as well; replacing both sides together is recommended for balanced handling.
