Removing the bb is not terrible. Slacken the drive belt. Remove seatback, remove drive shaft cover, mark drive shaft to bb flange so you can get them back together in the same orientation. Unbolt bb and wiggle it away from belt and car.
Opening up the bb after you have drained it is easy. Remove bolts and use two large flat screwdrivers to pop off the side plate and pinion gear. If yours is older i would be tempted to have a new gasket ready to replace the old one.
From that point on i have not taken out the shaft seal. Refer to the MTWC instructions.
