1999 Honda Accord Front end squeaks and reocurring alignmen

My front end passenger side suspension squeaks quite loudly when driving, no clunks or rattling noises though. It has just started within the past month and it's wintertime. The front struts work well and don't continue to bounce when I push down on the sides of the front end. The handling quality hasn't diminished noticeably either yet. As a related note, my car is currently out of alignment and tends to go out of alignment quite easily as this is the third time in 50k that I have had to get it aligned. What should I inspect that could cause a squeak, possibly be related to alignment issues but without noticeably affecting suspension performance - balljoint, control arm, bushing of some sort? Thanks.
