Sway bar end link question
 

While looking under the truck to see if I can find out what's making the noise I keep hearing, I found that the end links had a lot of play to them due to the rubber boots being old and dried out. I can hold the bottom with just two fingers and turn them from side to side a good bit with very little effort. Is this an indication that they should be replaced? I can't imagine that they should have that much play to them.
