clunking/rattle-passenger side rear-2003 highlander

[alkazoo]

hi forum, my 2003 highlander has developed a clunking sound which you hear whenever the right side goes over any type of bump(railroad ties/manhole covers/speed bumps etc). Its coming from the passenger side rear area. Ive removed the spare tire/jack/plastic tray to try and isolate but still does it. Not hurting anything it appears but annoying just the same. Best i can figure its in the general area of wheel well/tire,either coming from underneath or inside panels. Its still under warranty but dont want to take it in just for that at this time yet. If its something i can tighten up just as soon do that.. Other then that, runs fine . 22k V6...thanks for any tips...
