Annoying Squeek

Figured I would ask you guys something about this. I've been experiencing the most annoying squeek coming from the driver side front tire when hitting the bumps. Recently i took it out for a spin and notice that it happens when im not hitting bumps. So i took off the aftermarket wheels and placed on the OEM and noticed it was still there.

I had brought it into the dealer telling them to fix the damn thing twice now. (Being one of those things that you have to drive on it to experience it and when you get it there they cant duplicate it pissed me off) Luckily they lubed up things under the car and it stopped for a little bit. And now it is back. I dont know whats going on was hoping maybe some of you guys may have experienced the same thing or know what it could be so that i can get under the car and check it out.

Thanks for your help.

Thanks for the suggestions. No Suspension upgrades or anything just stock, HOWEVER I did have to take it in before for the same squeek they said that there was a leak in one of the shocks. So they replaced that. Im gonna give it a shot next time theres some fairly good weather , wanted to shine her up anways and spray the **** out of that ****. Hopefully that works. Lol. Anyways ty again for the input.
