Yeah mines pretty bad man happens on the smallest bumps and is loud like some f150, i can make it happen on both sides just by pushing on the fender. I've read about everything from sway bar spacers to just some silicon spray, i'm going to try the spray thing tomorrow i just got my duratracs put on today and going back for the first alginment since lift and tires went on. I'm hoping between the spray and alginment it goes away, i want my truck perfect never owned such a nice machine it's all been jeeps and old broncos, i want to keep it as clean as possible on all fronts lol heck i spent $35 on a stupid light switch for my fogs just to keep it looking factory. Lol but don't mind me i'm an idiot lol i was pissed when i got some rims for free from discount tire today cause the tires wouldn't clear on the stockers, free rims and i was mad i couldn't have my 5 stars, lol i am a fool, lol.
