Your car has numerous bushings in the front end, and without a little more information it would be hard for anyone to identify which bushing(s) you are having problems with. Take your car to a mechanic you trust, and ask them to check out the front end. Explain up front that you hear some noise but you really want to find out want it is before you agree to any repairs. They should be able to provide you with a list of parts that need attention and then individuals on this board can offer advice on repair options. There are ways to get quality replacement parts cheaper than the dealer.

Just my opinion, but it sounds like you need sway bar links on both sides.

If you can't get the link to work look for item # 7917343342 on EBay. $25 for the pair +S&H is a great deal and if you can change your tire you can put them on yourself in about forty minutes.

Good luck,
