00 Cherokee,4WD front rotor is frozen on. Soaked it with WD-40 and banged
it with a hammer. Wont release. I dont want to damage the hub by repeated
hitting. Whats the best way to get this off. Do they make a puller?
Thanks

Use PB Blaster. WD40 won't do squat.
Tap around the edge from the engine side and from top, bottom, front, back.
Just lots of taps. tap.tap.tap.tap.tap. Sometimes they get a bit tight around
the hub, but usually discs just pop off. Keep hitting it with PB blaster or
some other penetrating lube (besides WD-40) and whacking on it. Your not going
to hurt the hub unless you wail on it with a sledge. It takes far more abuse
from daily driving than you can put on it with a mallet. :)

Sometimes heating the hat up with a torch will help, but watch out as many things
around there tend to react poorly to open flame.

For really nasty stuck on rotors I have a large gear puller that fits.
Hit the joint with PB Blaster, Kroil, or Liquid wrench, NOT WD-40, set
the puller on and crank it up. Most of the time I plan to toss the old
rotor and install a new one so I don't mind putting a pretty good bow in
the rotor. If it is still stuck, give it a solid wack with a BFH. Be
carefull, if you have it under tension with a puller, it can land 20
feet away.

I think my #1 most used item in the toolbox is Liquid Wrench. The only time
it's failed me yet (after giving time) is one carriage bolt on my rear seat
that had to be torched, drilled, and finally cold chiselled off (not fun!).
I'm currently soaking the wiper motor gear assembly in some right now since
my "wiper problem" post from before was because the damn gear is seized
(motor works fine thankfully). Hopefully by tomorrow it should be loose.
