Well it really depends your front could be the Control Arms, Endlinks, or maybe a loose strut. The contorl arms are very exspensive to replace, the endlinks aren't at all, and a loose strut can be free if you know the torque spec and have an 18MM socket and torque wrench.
The rear might be worn Swaybar endlinks or the Sway bar claps have come loose. both are fairly easy and cheap to replace.
In the rear you would here a squeeking instead of a clunk for bushings requiring grease.
