yeh probaly a bushing... but i could also be impropperly inflated tires... im gonna say bushings cuz it sounds like it....umm at a dealer u can expect to pay alot..... if u go to a mechanic they may tell u that u need a whole upper and lower control arm... but they are lieing....just get the bushings and tell them to install them.... i havnt looked at mine lately so i cant give u a perfect example of were they are at and how to check them.... umm usually if there is no buishing there will be a loud metal on metal sound when u hit a bumb even small... due to the fact that the control arm is hitting something with no rubber cusion.... if u dont have that sound i would go to improperly inflated tires.
