i have a 2003 f250 sd.i have 52000 miles on it.i noticed that it squeaks when turning.the vehicle drives fine and there is no play or wobble in the ball joints.i got one of those needle greasers that goes on the end of a grease gun.i am able to get grease past the seals into the ball joints. it stops the squeak but does not last long.i know the real solution is to replace the ball joints.i just dont want to replace a good part that makes a little noise.anyone else out there have this problem?

 

Yep, I had this on one of my right side ball joints. Except mine had a little bit of play too. I replaced all four.

I found the boot had a really small tear in it which was letting water and other crap in there, removing the grease, and drying it out. I figure yours is something similar.
