I pop the seals with a pick then clean the bearing with solvent,warm soapy water, dry with compressed air being careful not to over speed the bearing, pack the bearing clear full rotate the bearing several times to make sure the balls and races are coated good.Then I wipe off every bit of the exces grease with in reason and pop the seals back on. This way you have grease where you want & need it the most,the balls & races.
