2002 Monte SS, ABS & Trac off lights are on, A Matco Scantool identifies a bad right rear wheel speed sensor.

Last Saturday, an inspection reveals the sensor is molded or pressed into the hub, with no mounting bolt like used on ABS sensors on other cars, I removed the brake rotor, and the 4 bolts mounting the hub to the axle, but could not remove it, how do you replace the right rear hub?

 

They can be very tough to remove from that point. It's basically corrosion holding it on now.

I used a nice big hammer with PBlaster and whacked it a ton. I know some people use air tools and an air hammer to knock it out.
