Can the balljoints be the culprit to your bad tire wear, of course. However how you maintain and drive your vehicle will play a major role in the end result of your tires. I have a newer truck with more miles than you do, and haven't been touched since I bought the truck over a year ago. I have rotated tires twice and the tires and alignment are fine.
But for the last time, your balljoints are not "defective." They are subject to premature wear which could lead to failure. Everyone and their mother is using this balljoint recall as an excuse for their lack of maintanence. Many people have reported seeing absolutely no change in the trucks handling, while others say they steering is tighter, and that is because of the alignment the dealership does after replacing the balljoints.
