Hi, I have an 03 CTS with 130,000 miles on it. I had it aligned last week, but then i drove over a curb divider that evening, which knocked the alignment out again I think because it pulls slightly to the left. Now, I notice that the steering feels a little bit loose when driving, but its much more noticeable at high speeds. I do not know if the loose steering was caused by the alignment or hitting the curb, or what could be causing it. When the car is turned off, any movement at all of the steering wheel causes the wheels to move slightly. I put a video on youtube at
showing how much my steering wheel could move without changing the direction of the car at 80mph. Any advice is appreciated, thanks
