This is a PA vehicle - PA-DOT pre-coats the roads with liquid calcium or magnesium before they expect a snow, and if you drive on the road when this crap is wet, you can feel your vehicle rusting around you. The stuff is nasty, probably takes more vehicles off the road in the long run than the snow and ice on the roads they're trying to prevent. Rust can be an issue.
"... rot around lower rear control arm bracket for axle." I'm assuming you're talking about an area about even with the firewall, maybe front a little on the frame?
