2018 320s Boondock. Ready to re-lube Dexter bearings, but can't find out if I remove just the flat silver disk with the T@b emblem, or the whole black cone and disk as one piece to access the zerk fittings. Searched the site and got lots of help on regreasing, but only when you're down to the rubber cap on the hubs. I hate to damage anything. TIA
