325xi wonders/shimmys at 80mph
02 325xi with 170k. When the car reaches 80 mph it starts to have a slight shimmey back and forth. Its not violent and the steering wheel doesn't shake, I can just feel the car swaying slightly. Brand new Lemforder control arms and ball joints. Also installed Power flex polyurethane FCABs new front tires ballanced and alligned all this done less than 7k miles ago. Can anyone give me some suggestions on what they think it might be? Would rtab's cause this?
