The options for rod ends always generates a lively discussion, here is a good starting point from the Pegasus web site: https://www.pegasusautoracing.com/document.asp?DocID=TECH00111&utm_source=201502-2&utm_medium=email&utm_campaign=201502-2

But it should not, you purchase the best series rod ends from Aurora or else you are purchasing them again too soon.

When do you know a heim joint is due for replacement? If it moves freely and has no play, can I assume it's good?

Take stress (load) off the joint and inspect it for play between the rod end ball and its outer race (the inner part of the housing). If you detect any play here, it's time for replacement.

Or if it doesn't move at all. :)

You also need to look for bending or cracks in the threaded area. If the corner has taken a significant shot, like bouncing over a large curb (or off another car), a crack/bend can form where the threads enter the suspension part. This is particularly true on the lower control arm heim joint.
