Welcome to the forum...
You most likely need to lubricate the slip yoke of the drive shaft...or possibly have bad u-joints but my money is the slip yoke...

Check the bolt and fitting that joins front sway bar to Lower A arm. Mine had a single intermittent clunk from passenger floorboard. Clunk was typically on deceleration and crossing a dip or right hand turn.
