I've been reading posts about shocks/struts and how they go bad around 60-70k. Do you think they (or some other suspension piece) could begin making weird creaking noises about this time? I've always had some odd sounds coming from the back of my car as I drive and have never been able to figure it out. Also, I think my parking brake lines are getting tense because my rear wheels sort of 'squeal' i guess you could say, as I start driving my car for the first few minutes, then the sound dissapears?
