I've thought my shocks were bad but they don't appear to have leaked or be leaking. others have told me they won't go bad without leaking. </div></BLOCKQUOTE>
Take them off one at a time and move them in and out while holding them vertically. If they have a good amount of force to move them, they are okay. If they move easily in and out, they are shot. Leaking is a symptom only, I have seen bad shocks be totally dry.
BTW, I have replaced my idler 4 times in the 2.5 years I have owned my truck. It has to do with the amount and intensity of your driving that determines longevity. I had one last 3 weeks, but they were a fun 3 weeks.
