do not get the suspension leg/VA removed at Punto 188

Hello Schraubergemeinde, has to remove the entire spring leg in order to break the spring leg at the front right. Unfortunately I can not get the two lower hold screws out. I got the mother off, I can also turn the screws (although with a lot of force). I sprayed rust solvers already a lot on it earlier. If I hit the hammer on the other hand nothing moves! Even with the upper screw where you can run well. Do you have a tip for me? Thanks & Greeting dachips
