stuck ball joint

[mehoff400]

what tricks are you guys using to remove stuck lower ball joint on a spindle? i have been hammering on the thing all day with a pick fork and some heat with no luck. unfortunately i only have a little hand held torch not sure if its actually enough heat to do anything. i am at the point where i was thinking about removing the upper ball joint sticking bolt/spacer/nuts through to push the spindle up while putting pressure on the lower ball joint.
