I have a 96 GT and when I hit 65 mph it feels like the rear end is moving back and forth its not bouncing up and down it feels as if it is moving side to side only at 65 and other speed and it feels normal 60 and below. Even when the clutch is pressed in the same thing happens. I dont know much about this car just got it. I was told that a new clutch was put in it a few months ago. Any ideas I have talked to a few people and they suggested ujoints tires etc. I would like to hear other possibilities if possible I can drive the car but I dont go over 50 in it and that just doesnt seem right I feel the car should go way past 50 but with this issue I'm concerened about breaking something. I have read on different forums diifferent issues but nothing that states the same issue I am having. First thought is to changed out the rear shocks and get the tires balanced. Thanks in advance
