1997 Chevy Astro clunking sound

Hi, Well this clunking sound is coming from the suspension on the passenger side. It does it when you drive it and more noticable the last 2 days. I had this problem a couple months ago so I lubed all the grease fittings and a couple were a little dry and the sound went away and you would have to rock the vehicle pretty good to get that sound to happen. This time again you do not need to push too much to make that sound happen. I looked under there and pushed the vehicle with my foot to pin point where the sound was coming from and I just used wd40 around the area Ii heard the sound with no luck. My neighbor said It sounds like a tie rod. I even replaced the front shocks thinking that was the remedy to the problem. I am including a photo of the area in question. It is wet from me spraying wd40.

Many Thanks Dan[img:02ea9e8b4c]http://www.2carpros.com/forum/automotive_pictures/238734_IMG_0597_1.jpg[/img:02ea9e8b4c]
