Is my car dead... rear suspension?
i noticed the other day a CLUNK CLUNK coming from behind me while i was driving... thought i needed shocks but then it dawned on my that my car wasnt low or bouncy... so i did some investigating in it to find (after two months of body work and paint) that the bar that attaches the rear end to the unibody rusted off lil bit... crappy third gen floors... so i can move this bar on the inside of the back corner of my rear seat floor closest to the door... it moves a ton? anyone tried to fix this yet.

i have seen that issue several times, nothing some good fab skills, sheetmetal and a welder cant fix.
However, have you removed the carpet in the car? what is the condition of the rest of the floor?

Are you kidding? Dealership? Most people at a dealership can't find the restroom, let alone actually use an advanced too such as a welder to correct anything! Welding is not in the Technical Service Manual - a dealership won't do it.
You need to check the rest of the body as mentioned above before you proceed - your car maybe rusted badly enough to just not make it worth the trouble. Then, if it looks fixable, talk to people that actually use welders for a living, like a body shop, or a privately owned muffler shop where the guy might help you fix it when he is not welding tailpipes.
If you get something welded in place to suffice, you're probably going to need an adjustable panhard rod to be able to get the rear end centered again.
Good Luck! And stay away from the dealership. Real world problems need real world hands on MECHANICS, not book tested "technicians"!

nuff said lol. But i do agree, if you have one problem with rust i would definatly check other parts of your car also. It takes awhile to rust through something. Thread
