I recently took my wheels off and got my tires balanced, but immediatly afterwards, I started hearing this popping sound in my left front tire whenever I turned right and hit any kind of depression...I thought it was a loose lug, but after I retightened them, I still hear the pop...I'm nowhere near a mechanic, so I dont even want to speculate what it might be...I have read that the ball joints are not very good on jeeps, but I'm under 28K...Any ideas?
