I keep getting confused between shocks and struts. Which goes in the front and which goes in the back? I know that I need to replace all four corners, so here are some questions. First of all, my car is really bouncy when going over bumps or doing abrupt maneuvers, and it feels floaty when driving on smooth roads (kinda nice but very detached from the road). My car doesn't sag, but I know it needs its shocks/struts replaced because when I do that "bounce test" on each corner, I'd get more than one return bounce. Anyhow, I went to Pep Boys and they have a replacement cartridge for my front. Now, is replacing the cartridge just as good as getting new struts? My car is a 1983 wagon. I plan on replacing all four corners, but I'm going to have to wait til the holiday is over. Will I damage or prematurely wear out any suspension components while driving my car with bad shocks? I don't drive it on unpaved roads, and I don't think my car has bottomed out. I am a little concerned about causing any further damage to the suspension unit or the car itself. Thanks.
