The other day we had some ice storms so I had to use the 4 wheel drive on my truck. Well when I put it in 4 wheel drive it would make a loud clunk noise but once it made that noise everything worked fine. Well now all of a sudden when I have my truck in 2 wheel drive I hear a clanking noise that sounds like metal is dangling from something and hitting something else. Its in my front left wheel and I can't figure out what it is. Something just sounds loose and the metal is clanking together. Any clue what it could be?
