I'm having a hell of a time getting the wheel bearing cap back on.

Trying the old and the new ones. Tapping with punch around the edges always pops one side in and the other out.

I've tried hammer lightly around the cap, which never goes in straight. I've also tried with a block of wood in front of cap.

There is a small indentation at center, but I'm not sure if this is strong enough to withstand direct hits from a punch?
