The hub and drum are one unit, so you will be pulling the entire wheel off of the axle. At this point it makes sense to completely clean out the axle, since you have to take it apart anyway, and replace the bearings, which you have to pull off of the old drum/hub and re-seat in the new one anyway.
You will need an entire new drum/hub (you can't get this kind re-ground), two bearings, a new magnet, the brake assembly, seals, several cans of brake cleaner, two full tubes of grease, a roll of paper towels, a grease gun, a bearing packer, a piece of wood and a rubber mallet to seat the seal, a tarp or something to keep your work area dust-free, personal protective equipment, time and patience. Brake cleaner and brake dust are harmful. Dexter has the instructions
for the hub/drum and
for the brakes where you will find the part numbers. Or at least a good start. There are videos on YouTube that show the entire process. ETrailer.com has the parts.
There are two different sizes of seal, so take a caliper and make sure you have the right one. Seals must be replaced every time you pull the wheel off of the axle. Clean the grease ducts out from the zerk fitting to the back of the axle using brake cleaner, then pump fresh grease through them before re-assembly, which will drive the last of the old grease out of the ducts.
I just hate that you can't inspect the brake without pulling the entire wheel. I would much rather have had a separate hub and drum. But it might be that all electric brakes are this way.
When re-assembled, do not expect tremendous braking power. Trailer brakes that lock at speed can grind the treads off of their tires within seconds. Yours will only be sufficient to keep the trailer from jack-knifing. Expect a longer stopping distance than when not towing.
