It fits on the Type S . The problem is where the ball joint sits. It's a bearing and not just a hole in the metal body. When remove the old one, that bearing could get pulled out with the ball joint bolt, cause the fit issue. But I replaced both of ball control arms on a 07 TL-S.

Hi Arthur, thanks for initiating contact. This control arm does not include the ball joints. The ball joint is sold separately. Let me provide you with both links to complete your order while the parts are in stock. Happy shopping!
