1995 Honda Civic Creaking Sound

I just got my car out of the shop and they balanced the tires, after having to reseal one. A couple days later I began to hear a creaking sound every time the car goes over a bump or other rough driving on the road. It's like the shocks are audible now. Could this be because of the car being balanced incorrectly or is it due to cold weather that has recently hit the northeast with a bunch of snow?
