I have not tried it on a bearing, but for a bushing, this worked for me.

Do you have a metal clutch alignment tool?

If so;

Fill the cavity about 5/8 or more full with wheel bearing grease.

Insert tool.

Tap on the clutch alignment tool with a hammer, a brass hammer is advisable.

Add more grease as needed & repeat.

The hydraulic pressure will start the bushing to move out.

Been a long time, but it always worked for me.
