So I havery a 2010 malibu ls. 2.4 L engine. 108000 miles. I have replaced all struts and shocks. Keep a great balance and rotation and alignment on it. Lower ball joints are New both front axles are new. Brakes are new. But yet everything I hit a bump I can feel it in the steering wheel. Harder than I should. I don't know what else to replace. Taking off in 1st gear there is a vibration thay occurs in the steering wheel. Once driving it a comfy ride. But hitting the bumps and vibration is very annoying. Can anyone help?
