Rear suspension problems Options

[JonMarkos]

Hey guys, looking for some input from those with more knowledge than me. My right rear wheel clunks when I drive. It sounds almost exactly like it would if you have ever driven off from somewhere without tightening your lug nuts all the way (my lug nuts are tightened all the way). I also have on new tires so that is not the problem. Is there a bearing in there that will go out causing this to happen? I noticed that the clunking goes away when I am going around corners which I attribute to the wheel being pushed up against whatever is loose (if that makes sense). Any help is greatly appreciated, thank you.

After looking at the rear schematics closely I believe it is going to be number 5 in this diagram that I need



I may even end up needing number 2 since the wobbling of number 5 may have loosened up number 2 as well. It is listed at 1sttoyotaparts.com as the rear arm. 1sttoyotaparts has it listed separately for years 95-99 and for convertible, or coupe w/ or w/o sport package. Is there actually a difference?
