Having difficulty removing a rear hub, it appears that the hub had rotated slightly and has the woodruff key in a bind. The threads on the hub are in very bad shape so my hub puller keeps slipping off the hub. I have soaked the area with penetrating oil and WD40 to no avail. Any suggestions.
Marc: I have read by some on the Forum that if you loosen the axle nut a turn or two and drive ti a bit and do the drive forward and backward it might loosen the hub. It is worth a try. Just be careful loosen a turn or two on the axle nut.
Is it a running car? Then loosen the nut a few turns, replace the cotter pin and go driving around sharp bends for a while until it loosens up.
If that doesn't work, try a knock off nut on the end of the axle, smack it with a sledge hammer with the wheel on the floor but the other side wheel lifted.
If that won't work either, try find a special puller that grabs a couple of wood spokes. If you can't find one, try make something that grabs spokes. You may have to heat the hub in extreme stuck situations, and that's risky for the wheel, but if you've got to pull a wheel, you've got to.
