I thought I might flood the hub with penetrating oil then flush with alcohol or acetone and refill with oil.
Will this work or make matters worse?
If something is rusted bad enough to be stuck like that I can't imagine anything short of opening it up will do it any good.
Soak it with Kroil or PB Blaster and see what happens but chances are if its rusted bad, your going to be taking that indicator out in pieces if its rusted into the axle.
If the indicator unscrews and the hub is stuck inside, you might as well just take it apart now.
They're easy to work on, once you do one, you'll likely take everyone you get apart just to be sure of what you have.
