Do i need to buy a replacement hub to install a JDM steering wheel on my car?

I have a 2003 hyudai sonata. i was already told that to remove the wheel i will need to disconnect the battery for some time due to having an air bag. I already have the steering wheel. some sites are telling me i need an additional hub of some sort. others tell me i dont. i dont wanna take the wheel off and have to need a hub if i dont have one on hand. thanks in advance for the help.|||yea you do.....your gonna need a quick release hub if its removable wheel......i bought my NRG removable kit for 320-comes with wheel quick release hub and this big *** hub lock(so know one could put there steering wheel on yours). you should get the hub that comes with your wheel...or it might not fit right....oh and taking out your stock hub is gonna be a *****....i did it twice and it never gets easier.
