Wheel scars extension?

Hello
If I want to make the wheel bearings in front of my 4.2 V8, I have now noticed that it is not so easy to separate/extend the flange where the wheel is scratched on from the spring leg.I have no explosive rings, pins, screws, etc. If one of you has already expanded the part and can give me a guide, or if it is possible.Not that it is even pressed in.
Thank you, Matthias
