Ok which one of you has had this?

since I live in Michigan its only fair I tell you have had ice problems. but within that this is not one of them times.
My H2 is an `04 Adventure and has only 32,000 miles, it has been making a weird clunk/pop noise under the drivers side floor. it like someone smacks it with a hammer while your going through twisting types of bumps. I don't know if its a cab mount or what?
FYI I already took a breaker bar and tightened all the lower control arm bolts and skid plate bolts. I couldn't find anything really loose.
