Nissan Repair: squeaky noise after a belt maintenance replacement, sway bar bushing, alignment shop

Question
Is there a reason why my car squeaks under the front wheels and my driver's side door 'chirps' (not noise from a car alarm.  The sounds weren't there before I had it serviced.  I should've taken it back and asked them, but i was advised against it by a parts man. i had it aligned and the wheel alignment shop, examined and found nothing amiss with my suspension,  just minor alignment adjustment, which i requested.
any idea in this area would be appreciated

Answer
Julie,

I would spray WD40 on the anti-sway bar bushing and see if the noise goes away.  I would do the same with the hinges on the door along with Armor All on the rubber trim.  I do not think they messed up your car it is just something that happens over time.
