I have the same problem with my car it squeeks every now and then somtimes it is really bad it even squeeks while turning left or right. The noise is coming from the driver side. I took the car to the tire shop and they told me I have to replace the whole left side sub frame. Would it be neccessary to do the right side as well. Does this worn dried out lower ball joint cause any vibration at high speed because I had the tires balanced and my cv-axle checked and it is fine and I still get a little vibration on the front dash and steering and also on the seats as well. If I replace my lower ball joint assembly will this cure my vibration.
