seeing this makes me scared of driving my car now with my rust issues..

Seen this before thats why it'* good to do a inspection on the under side when changing oil!

Hog Man asked me for more information but I didn't get his message until just now. I linked my e-mail to the word 'note' above. I made up a 10-page booklet on how to do it.

Nightriderr, Did shops do your oil changes?
Someone should have seen that stuff pulling apart long before it came to the complete disconnect of subframe/bushings.
Salt belt eats though stuff and bushings/bolts etc, can rot if not washed frequently.
A salt concentrated neutralizer spray in winter may be a good idea after coming in from the outside gunk. http://www.rockauto.com/catalog/x,ca...parttype,10721
I know with my cars if it does have to go though salt, I try those touchless washes, or better those manual power wash bays where you can really get it clean underneath!

Wowzers! Lucky that steering shaft didn't separate! Seen lots of rusted out cradles in this part of the salt belt, mostly on Cavalier/Sunfires though, mind you we don't see a lot of Bonnevilles up here unfortunately.
