Thanks to NE weather and salt the ones on my 2002 are starting to need rescue before they get real bad and the rust spreads. has anyone ever changed them and how large a project is it. Car is still under 100k runs great and no reason to sell. One of the best car buys in my life. I have had it since 2002 and only 2 big problems 1 fixed rusted brake lines and has coolant fouled issues to deal with soon. The rocker panels now the 3'd one. If I can clear up the coolant problem rocker panels next with only future problem imagined the exhaust system finally giving up.
