my truck has 200,000 miles 4 cyl automatic 2 wheel drive. when i turn, like when i make a u turn the wheels feel like they are out of round. I have to do a 4 or 5 point turn just to make a u turn. also when driving on a slightly bumpy road the wheels start to shake violently to the point where i have to stop. I did grease all the tie rods and ball joints on the front end a week before this problem started.
