I have a similar noise coming from the drivers rear. Ive been told to change the rear sway bar bushings and that will do the trick.
Ive had mine up on a lift and tried my hardest to find/duplicate the noise with no success whatsoever so I'll be watching this thread closely. good luck

"It cannot be emphasized too strongly or too often that this great nation was founded not by religionists, but by Christians; not on religion, but on the Gospel of Jesus Christ. For that reason alone, people of other faiths have been afforded freedom of worship here." Patrick Henry 1776
