Dead easy, take off front bearing carrier, this holds the taper part, this simply prises out, BEWARE there will be a shim behind it, so don't lose it, then the bearing can be pulled from the shaft, it's not a(stupidly) tight fit at all.
Make sure to install shim before new bearing, then use a good sealant around flange of bearing carrier, and also on the 4 bolts that hold the carrier on, make sure the "top" marking is observed on the bearing carrier when refitting.
