i did too, but i did mine during my rebuild and the carrier was all apart, to make sure all the filings could be cleaned out, i think some guys have done this while it was on the bike, so when you grease it, it just pushes the metal shavings toward your bearings, on my '96 i did as suggested and removed the seal from the inner side of the bearings, so grease can get into them, but on this '01, i left the seals in, since they're brand new and i repacked them with good red grease, and am using the grease in the carrier to just keep water out
