Hello, I am in the middle of changing the driver side lower control arm in my 2005 Subaru Forester. when I was trying to loosen and remove the large two bolt bushing bracket on control arm,the bolt that is closer to the outside of the vehicle was very difficult to turn , after it was about 3/8" out it stopped moving and something snapped. it wasn't the bolt , it was the threaded anchor behind it now the bolt just turns, doesn't come out and doesn't tighten How can I access the back of said bolt?
