this problem started a few months ago. i was turning left and it felt like the car shifted 2 or 3 inches farther than it should have and it also sounded like a bolt snapped. ever since it shakes under normal acceleration and pulls to the left under heavy. i just replaced the control arms, sway bar linkage, and struts and springs. the bearing and cv shafts have also been replaced recently. it also has an odd shake turning left now as well. i think it might be the metal strut rod bushing where it passes through the sub frame or the rack and pinion. i have had problems with the bushing before and welded it back to the sub frame.
