Go to
http://www.infinitipartsusa.com and check out their listings for your car's suspension. They won't have all the parts listed on the website, but check out the diagrams, and then give them a call on their toll-free number. You can try other places to comparison shop, but Scottsdale will beat almost any local dealer hands down if you don't live in AZ. I think you should replace all rubber parts. These include the upper rubber seats for all struts and the rubber bushings for the rears. You will probably need new spacer gaskets too. These parts will probably be just over $100 for all and make the ride much nicer. At your mileage I can guarantee that your rear lower shock bushings are dangerously worn if they're original.front upper spring seats 54034-60U05front spacer gasket 54329-60U00 (non-active)rear upper spring seats 55034-60U05 (non-active)rear strut bushings 56217-71L00 (non-active)rear strut bushings 56218-71L00 (non-active)rear stop bumpers 55248-2Y000 (non-active)
I don't have the part numbers for the rear spacer gaskets or lower strut bushings. Also verify the numbers before buying anything; I can't guarantee they're accurate, just what I have in my records.As far as the quote you got, it sounds pretty inflated. Ask them what the book time is. Book time is published and doesn't vary much from one source to another. Then ask them what their labor rate is. If both numbers are accurate, then listen to the BS excuse they give you for the discrepancy between the product and the quote.
