when I got my truck it had a B&W gooseneck installed. I was able to get the pin out of the ball but the ball was stuck upside down. I let it sit with PB blaster on it for a few weeks and tried using a rubber mallet from the underside to get it out. Then I switched to some padding on the ball and a sledge hammer. Nothing was working. Finally I got sick of the ball being stuck and decided that it was coming out. I go to school at a motorsports shop and pulled my truck in for some work. First I fabricated a bracket on the cnc plasma cutter that I could weld to the bottom side of the ball. I used a 220 Miller MIG and put some nice beads down on the bracket to hold it to the ball. The tailgate was removed and an engine hoist was hooked to the ball. We jacked until the rear wheels were about to come off the ground. NOTHING! The ball didn't even budge. One of my buddies beat on the housing around the ball while another beat the ball side to side from the top. Finally it popped out. Here is a pic. Anyways if you all have a stuck gooseneck ball this is how I got mine out. I used a 90 degree wheel with pads on it to clean up the ball. It now sits in my truck box until I need to use it.
