^ Dunno? Part#s differ but bearing size is the same. Abs collar (tone ring) may interfere? Might try it and see if you can save $100+ esp. if youre tearing the drum equipped one down anyway. Rear hub/bearing assemblies are a piece of cake on disc or drum set-up.
From what the previous posters have said, no. I believe they're saying that you can't interchange a hub assembly (that's the bearing) from disc to drum. I guess if you converted to disc brakes, that would work?
The hub assemblies do not interchange on rockauto, and they look visually different.
Someone else will chime in if I'm wrong.
edit: I guess this is a little older than I thought, ooh well.
If youre separating the bearing from the hub (not advised), then yes, the bearings themselves are the same size. They have to be pressed into the receiving hub to the precise location and if there is any wear in said hub, they wont sit right and stay put. Been there, done that. Also, a pain to remove good bearing from hub without damaging.
