We made a u-turn turning the wheel all the way and noticed that when you turn hard either way at 5 mph or less to do a u-turn type turn, you hear popping sounds from the front end. Any ideas what this is! Its brand new! Sounds like clicking or like metal to metal popping. It also pulls a little to the right and Ive checked air pressure. We are just driving it around pretty easy and putting some miles on it. I dont think this noise is normal or good. Sounds like the right front but pops in either direction when turned hard. Thanks for any help or clues. I will take it to the dealer next week.

 

I drive a Crown Vic. at work and the crown vic does the same thing. I asked the mechanic about the issue and he pointed out to me that there was a piece of plastic, some sort of cover in the wheel well, that when you turned sharp and slow enough the tire would catch it and pull it back until it "popped" back into place, I haven't noticed it on my lightning though. Just check the fender well, you should be able to see some wear marks on any of the plastic.

 

Sounds Like you have the famous Clunk. My 01 had it as well. Sounded more like Metal to Metal also.
Get it fixed soon as it will wear the tires...
