Accord squeak/creak

Lower control arm bushings and upper strut mounts can make squeaking noises. The best place is a tire and alignment shop for an inspection. I'd suggest going back to the place that did the previous work so they can double-check their work. Some replacement lower ball joints are an improved design over what came originally on the car and they will have grease fittings. Sometimes we forget to add the new grease when we install the joints, and sometimes we just don't get enough into the joint. That can also cause a squeak.
