I can't seem to get the spindle nut off. Therefore I can't get the hub off. Any suggestions?

2001 Honda Accord

Pb blaster and either impact gun or a half inch drive with a big pry bar maybe 3'or bigger the better.

Well i use air, and sometimes the nut still needs heated. Lock the hub with the brake or use a good pry bar locked against the ground. Get your 4 ft breaker bar and stand on it.

A three foot black iron pipe extension over a 1/2" breaker bar.

Not bad suggestions so far, but just in case you don't have the right size socket they have them at some auto parts stores for free, just put a depots until you bring back.
