How do you extract spline bolt that holds lower control arm bushing on a 2004 Nissan Xterra 4WD?

One tuff bolt to remove! If replacing the LCA just cut the LCA close to the bushing/ bolt area, then find a container that will fit around it. Fill container with penetrating oil and let it soak(submerged) for two days. Should break free with a few whacks of the BFH or impact gun.
