Front End Issues

[Carol]

I started hearing a noise in the front end within a week of purchase, had the car back to dealership 3 times. Finally it was bad enough they found the steering rack was bad, only showed up if I drove the car for 30 mins before taking to dealership.
One month later, noise is back. They had to replace the tie rods ends (second set), changed the first set when they did the steering rack.
One week after I got the car back the noise is back and now I am having problems with it pulling to the right and steering wheel shaking. I think Chrysler needs to look into this problem, dealership said it was bad parts from the supplier but don't think all of this should happen on a car with only 20,000 miles.
