Can a bad strut cause front end wobble?

i think so. i dont know much about cars, but my front driver side is making a loud squeaking noise frequently when going over the slightest bump in the road, and its very bouncy. i notice that when im driving it seems the car sways a little, and when i reach higher speeds it seems to shudder a little and sway more. im also now noticing a cranking noise in the suspension when i turn, which im afaid is the ball joint or control arms(which i just had new ones installed months ago) or the axle, and im sure its being caused by all the bouncing putting stress on it. ive been trying to put it off thinking its not a big deal but im going to have to get it fixed before i have even bigger problems and more expensive repairs. i suggest you do the same.
