I have a 2000 Ls v8 and when I'm driving it down the highway the front end is loose. It goes back and forth slightly on the road. It feels like the wind blowing it back and forth but I know it is a problem with the front. It doesn't vibrate at all. It just doesn't hold a straight line. I need to get it fixed but i was wondering if anyone has had any problems like this and might know what kind of problem i am looking at and how much for the repair. Thanks
