Ok, I will expand on the candle wax technique for you Johnny.
A candle is used after you heat a part red hot to suck the heat out of the (usually) inner part that was heated. You need a big candle like you would use on the dinning room table. It will cool one part and shrink it away from the other part.
Heat the piece as hot as you think you need. And then apply the end of the candle directly to the end of the axle to suck the heat out of the axle as it melts. This will make the axle shrink which will break it loose from the fork leg. If it is stuck in the wheel then a press will be your best friend. Apply pressure to the axle while supporting the wheel hub and just leave the pressure on it for a while. If it is just stuck it will give up with a little patience. If it is stuck really bad with corrosion then it may take several days of letting the pressure sit and convince it to move.
Constant pressure is something that people don't use enough. A friend couldn't get the center hub off of a bush hog so he drilled and bolted a 4 x 4 across the center shaft and through the bolt holes for the blades. Now we had tried the old shock it loose with a hammer technique to no avail. I laughed and said that the 4x4 would never make enough difference to get it off and told him to come by the shop and get a piece of channel to use on its edge. Several days later he called and said it was laying on the ground as it had fallen off all by its self with just the 4x4...
You may want to try some of this stuff too. Its all I use. A little goes a long way. Makes PB look like 3in1 oil... And all I use WD-40 for is to mount and dismount tires. Doesn't cause rust like a water based solution will.
