I took my car down to OC, MD this weekend for Cruisin and on Sunday noticed a random clanking sound. It progressively got worse on the way home. It’s very random though. Sometimes it sounds like it’s coming from the front, the rear, or in the middle of the car. I’m not sure what’s going on. It sometimes does it over bumps and other times over slightly rough pavement. I had a mechanic look at the car and he says everything is tight. The only thing he noticed was that the inside of my driver’s side tire has a huge crack on it. However, it wouldn’t seem like that would be the cause. I’m not sure what the hell is going on at the moment. Any thoughts?

 

I moved the DSpecs from 3 turns out front and 4 turns out rear to 7.5 turns. It seemed to help a good bit. However, the clanking is still there. It's coming from the rear, but the exhaust seems to be tight.

 

Check alll the control arm bolts, shock bolts, sway bar bolts, front sway bar end links,

 

Ditto. Sometimes that stuff can losen up. I don't know much about the BMR panhard rod but if it has jam nuts, you might want to check them. The ones on my Steeda kept losening up and it started clunking. re-torqing and some locktite put an end to that.
