Thanks for the reply. It's the front control arms I'm concerned about. I do have some slight edge wear on the tires, I can also feel a bit of a clunk in he front end when driving over bumps at low speeds. From what I understand, the front control arm ball joint typically lasts about 100,000 miles. If that's true, I'm way overdue......
