What is the easiest way to get the rear wheel hub on?

After replacing the shoes it should look something like this (that's the left side of the car). Did you remove the drum and bearing together with the single large hub nut or the entire drum and hub using the four bolts on the backside of the drum? If you removed the drum by using the four bolts on the back you will need to line up the bolts properly first, but if you used the large nut it should be a lot easier. I used a rubber mallet and a decent amount of force to get my drums back on.

Important: If you removed the drum using the large hub nut you need to torque it down to 175 ft-lbs at reassembly. If you don't, you run the risk of premature bearing failure.
