Go rent you a ball joint puller and take care of those puppies yourself! You can't be afraid to wrench on the Jeep.

People need to remember that the factory ball joints only last so long once you go with bigger wheels and tires. From what I've been told, the OEM ball joints already come from the factory with a lot of play in them compared to other makes. It only helps them go bad sooner rather than later. In your case I would just keep the new ones until your factory ones go out and then swap your new ones in. Save the money and do it yourself.
