Hi I have a 2008 SE CC 4x4 with 113,000 miles. The passenger front suspensions all of a sudden bangs hard when going over a drop off like a pothole. I looked and the ball joint bushing pad whatever you call it the rubber filled with grease ( I think because a blob of black grease it sitting there now ) is pretty much crushed. Is this an obvious ball joint replacement issue or could my struts also be shot. The truck feels s little squirrelly now when driving not much but you notice stuff like that after all the miles I put in on my three Titans.
