Last night I was driving around in my 94 RS with my girl friend, it has minimal modification(AEM intake, ground control). Anyways, when I made left had turn a pretty bad knocking sound happened under the left fender, it sounded like it was coming from the suspesion some where. Since last night it has gotten worse, now when I let off of the gas at slow speeds in 1st and 2nd it starts knocking. I think it could be the CV joints, could I be right, how much would it cost to replaced them, is it a job I can do my self???? Please help, any info would be good!!!
