Ok.... bought my lincoln LS in may of 2012. It was in good shape. I had inner and outer tie rods put on it, new breaks ,tires and ect.... car drove great ,tight steering and excellent feel to the car. in october i started to notice a floating feeling when driving and could feel the car sway slightly back and forth. started to pull out of work one day, backed up a little and it sounded like the motor fell out of the car. CRAzy! come to find out the bolt that held the control arm and the joint together came loose and fell apart. the body of the car was resting on the tire. so all together i had to have the control arm and the ball joint replaced. $800 dollars later it was fixed. 3 weeks later started noticing a new sound every so often from the same side that was fixed.It got louder and LOUDER. Took it to a shop and they said it was the inner tie rods. replaced them again. two days later the sound returned again. now it is constant. It sounds like a door creeking open. it goes faster with the speed of the car and stops when i press on the bakes. I see nothing wrong with brakes and there is no play in the wheels so i do not think it is the wheel bearings. I seriously need help if anyone can give their opinion i would be very thankful. I have poured tones of money in this car that i really enjoy and just want it fixed.
