I just bought a 1998 Land Rover Discovery about 3 weeks ago. When we are on the highway going 65-70MPH, & we hit a bump or groove in the road, the whole car shakes. It's not your normal shaking. The whole car vibrates so badly we think were going to have a wreck. It stops after a minute or so but it concerns me b/c I have a 7 month old son whom I dont feel safe in the car right now. Someone said a pin may be loose somewhere but no one is sure. I cant really afford to take it to the dealership so does anyone have an idea as to what this problem could be? Please Help!!!
