Mine have not as of yet. I had 2 new shocks and springs and barings replased on my frount end done a few days ago. I just been working hard at work, paying for some bills, not fun at all. its been raining here and will be for the next week or so. I have to help my dad out with getting the stearing shock off his jeep. Its a little rusted so i will be using some PB blast to help me out. If that does not work, thats nothing a grenade can't handle.LOL. A fun weekend project. A bad day working on a stubbern car with your father is still better than a good day at work!
