It's a cup & cone.
It takes the cartridge type removal tool however + the lock ring tool.
This might be what they call a semi-cartridge type???
Many of these have the splines cast poorly and I seriously recommend attaching the removal tool to the fixed cup like in the pic.
You need it tightly engaging the splines, else you might ruin the tool AND screw up the cup.
Trying to "chisel it off" or similar tactics will leave you in a bigger pickle.
Apply some "real" penetrating oil now. Extra soak time is GOOD! Reapply a few times as it wicks in over the course of a few hours/days.
