It might seem like it but no. You have to disassemble the hub. Once you get your spindle nuts out the drum/hub come right off. Your outer wheel bearing will come out as well. Basically set the back of your drum on the ground and whack each of your wheel studs with a 4# sledge hammer. One or two well placed blows will do it; you might buy some nuts to thread on the end before whacking to protect the threads. 1/2-13 threads I believe.

Basically put your drum on a new hub and your back in business. Your gonna want to check the hub to make sure the disc and drum hubs are the same. I dont think the drum types are as common as the discs. If they are the same this should be a cheap trip to the junk yard. If different hit me up. I will have some extra drum hubs in a couple weeks; currently switching mine to disc. One is yours for a bone and shipping.

I think the hubs are the same on both the drum and the disc brake setup. Not sure though.
