2003 Chevy Malibu is acting too old for it's age

Howdy,



I have a 2003 Chevrolet Malibu with 90,000 miles on it. I’m the original owner and have taken the car in for maintenance every 3,000miles as doctor prescribes.



For about the last 10,000 miles I’ve noticed that whenever I make turns I get a loud creaking noise by my rear axle, very similar to someone walking on a wooden floor in an old house. This problem has gotten exponentially worse in the winter (I thought my car was going to fall apart this Sunday in the 10 degree weather) but slowly dissolves as the car warms up in 10 minutes or so.



I’m no car expert at all, but after listening to Car Talk for a few weeks, I was thinking there may be an issue with the bushings and they may need to be replaced/lubed.



I’m not sure if this is correct, but that’s what my educated guess is.



PS I just moved to Cambridge just south of Central Square, do you recommend any mechanic in this area?
