At what point should the tie rod links be replaced? The bushing "looks" good, and the ball joint boot is good too. I cannot feel excessive play, but it is a bit looser than new. How long do these last? Is it worth the $50-60/side to replace now? I have everything apart as part of a suspension rebuild (the thrust, torque, and camber arms and support joint were shot) and would prefer to change if its likely to go bad within 60000 miles/1 yr to save a trip to the alignment shop.

Thanks.
