1. I use a puller, forgot if it was 2 or 3 jaw but it came right out.
2. Be careful when you do this because when it comes off the puller jaws sometimes swing out and might hit your knuckles. I use a long socket wrench and slowly rotate it at the same time stand to the side.
3. When it comes off it’s a loud “clink” so look out for this. At the same time your puller will probably fall to the ground .
Good luck
