Mine may not be attached but it clearly looks like you have a much bigger problem.
I'm not missing huge areas of metal like that. Mine is just rusted right around the bushing area.
This car is my baby so I want the best for it. I'd want it fixed properly by someone who knows what they are doing, and will support the engine properly while removing the subframe. Of course this type of shop would not be cheap, which will probably end up being devastating to me, since I don't want to lose the car or a lot of money I don't have.
I just insured my Sebring so it'* ready to put on the road....my premium more than DOUBLED...almost $3200/year with both cars insured. :(
I need this fixed ASAP so I can take the Sebring off!
