How to remove and install the Boxster axle flange
 

My car (97 Boxster race car) in need of a fresh axle flange for the driver side.
I don't see the bolt to loose to get the axle flange out of the car.
Reading an article online, for the older 911s, there is a big bolt in the middle.

For Boxster (97+) and Carrera (99+), do I just use a couple of pry bar to focus it out?
Please help.

thanks.
