Its most likely your lower control arm ball joints could be shot or most likely your lwr ctrl arm bushings are blown. The bushings are a more likely cause since they wear out a little faster. No offence but fromy our responses I am led to believe that you dont know your way around cars very well. If thats not the case im sorry but I reccomend a person of your know how about cars you might wana take it to the dealer for bushings. They might offer you the lower control arms to and you should go with them. After those 2 things are replaced your steering and body roll will become better.
