Upper Control Arm bolt

Can you get a shallow 1/2" drive impact socket on the bolt head & work it back & forth a bit at a time with a breaker bar to free it up?
The bolt spins freely... It's "stuck" to the inner part of the bushing not allowing it to back out. I've cut one side of the bushing and bolt,but not enough room to cut the other side.. I hate to do it, but I may just have to cut the control arm.
