Hi, I am wanting to purchase KYB GR-2 struts from tirerack.com for my girlfriends car. The back is making a squeaking/swooshing sound when going over bumps and the front it creaking/cracking. The car has onl 82k on it and is not driven hard. I was wondering what is the usual replacement cost for both the dealer doing it or a place like TireAmerica or some place like that performing the work if I supply the struts. What I need to know is just the install fees. Thanks in advance
