I also replaced it myself, just make sure you order a bearing with a new ABS sensorring. I removed the old bearing by hammering it out with a fitting socket from my tools while i rested the drum on 2 blocks of wood.
The new bearing i first put in a plastic bag in the freezer for a while, heated the inside of the drum to about handwarm and used the old bearing to gently hammer the new one in.
Replaced the ABS sensorring and refitted the whole thing.
Of course, a press would have been easier but this way it also worked.
