Did you grease the bushings prior to installing them? Also did you add zerk fittings to the a arms? After installing my lift wth the green bushings it creaked pretty bad. I did install new swaybar bushings which helped some but I endied up htting the zerk fitting with more grease and its been quiiet now for 1k miles. If you havent added zerk fittings you may want to add them to keep the squeeks away.
