I have some noises coming from my suspension. I have to explain that I know nothing about the car. I know that it is making a sqeeking noise and I am told that is the shocks but there is also a creeking noise that only shows up sometimes. I am going to replace the shocks but I am wondering what this other noise is and if I should be replacing something else while I am in the process of doing the shocks. Any help would be great. Thanks
