Ok first off i am a total newb with suspention parts. Look i cant even spell it right. OK for the last month or so my cars front suspenion has been acting werd. I think its the ball joints but i could be wrong. When i hit the accel its like the whole front end shifts to the right and then when i let off it goes back into place. Also it has fucked up my 2 month old tire, which i waited to long to take off and put the steelies back on. But the thing is i dont really know where the ball joints are. I think that they are the ones cirlced in red but, i was also thinking it was the things in yellow?

OK so if you guys think that its the balljoints are they hard to take out and replace or do you think i should bring it in to a place and get them done? also are they expensive?
Here is what it has been doing to my tires. Can you tell which was on the back and which was on the front? ha i can
