I have the same problem right now with a 98 ATX. I got a rough estimate from the dealer of over $1000, of which at least $600 is labor. It is a big job. After reading the repair manuals and doing a little search on this site you have to drop the sub frame to get at the rack. I know my son and I can do the job, it just might take us for ever. Not sure what I am doing yet.
