What type of upper ball joints did you replace with? OEM, or a set of ball joints that have a threaded hole on them for a Zirk fitting(MOOG)? If there is an acceptable amount of play in the joints than you should be fine. It is probably some bushings that are squeaking. Does it happen when you are turning the wheels or any time you hit a bump? It could be a pitman arm, could be lower bushings, many things in the front end can cause a squeak.
