I have an unusual problem I think. I have removed the lower a arm, both ball joints, the tie rod and one bolt (the after one) from the top a arm. I have the nut off the forward bolt but that bolt will not come out even though I can spin it around with a wrench. Anybody out there have any idea what could possibly be holding it? It doesn't appear to be bent. It is a difficult spot to whack it hard with a hammer.
