What are signs a ball joint may need replacing?

Clunking or knocking over bumps, wandering or loose steering, and uneven tire wear can be signs of a worn ball joint. Have the cause diagnosed before replacing, as these symptoms can have other origins.

Should I replace the ball joints on both sides?

Ball joints are serviced per corner, but many technicians recommend inspecting the opposite side at the same time. Replace as directed by your vehicle's service procedure for balanced front-end wear.
