You can tell if the snubber has popped out or if you forgot to engage it while going down the road because you get a sensation of "surging back and forth" is the best way I could explain how it feels. Sometimes the snubber won't stay engaged no matter what. You cannot refuse to pull a set because the snubber isn't working. Dispatch will say it isn't a DOT required item. You could always swap the trailers around on the set as long as the %'s are right, though.
