you will need 2 people to check if its the steering wheel one to look under the car and the other to turn the steering wheel (front of car jacked up) there should be little to no play in the steering rack, idler/pitman arms or radius rods. if its not this i would say bushings, ball joints, or worn struts.
Im not in the car driving so i cant be sure

at least i didn't say get an SR.
