i got this annoying rattling noise comin from my rear suspension when i hit a bump, i think mabe my struts are gone, back end feels kinda soft when u put weight on it drops about an 1nch and a bit mabe, i looked under the car and there looks like its 2 struts on each side or something, 1 vertical and one diagnal sortive, i just turned 18 and this is my first stang so i don't know all the parts on my car yet, so i wanna get new struts for both sides in the rear will that solve my problem? and will it solve my problem when i let her rip in first and it feels like the rear end is jumping? and any cost estimates? (in canadian money)
