1998 Nissan Altima CV boots and/or axles

Hello, thanks in advance for the help! My car seems to creaking alot where the CV boots would be. Also it sounds like an indicator noise (high pitched consistant whine, not too loud though). I had the brakes checked so thats not it as far as the whine, it also creaks pretty loudly when I go over bumps and sometimes when I turn hard or quickly. Was told(not by a mechanic) that it could be the CV boots! Hope someone can help, Thanks, Wendy.
