Unit bearing ( hub ) removal

I am trying to replace the ball joints on 2003 F 250 SD Crew 4WD. The studs on the unit hub seem frozen into the knuckle.
Is there a way to remove it without destroying the bearing ? What kind of puller works and where do I get one. I've tried " wiggleing " , tapping with hammer, and lots of penetrating oil . Any suggestions?

If I do get it out , dead or alive, should I put anti sieze compound on the studs when I reassemble ?

Thank you.

RE: heat

Yes, I heated the knuckle unit sparingly with a torch. Ford warns against applying excessive heat to the knuckle. Local Ford service tech said the unit is a " light" press fit, this sucker seems really stuck. Truck has 50k , babied since new. HELP

I Changed Mine But I Heated It Up. Have You Tried An Impact Wrench? I'm Not Surt If You Can Get One In There. I Know It Took Me Awhile To Get Them Loosed I Think I Heated Than Tappped Than Put A Pipe On The End Of My Rachet But Becareful Not To Break. Either That Or Just Let The Ford Place Do It Might Not Be Worth The Trouble.
