Must be an eastern thing. Cars from Arizona don't even need wd-40 let alone pb-blaster. Not even after 15-20 years.
Still, there is a proper tool to push the axle out of the hub. It bolts onto the lugs and then you just crank it out with a hand ratchet or air impact. Oh, and since I've been in texas and alabama, I've had to buy some wd-40, but it has been sufficient.
