If they won't take grease, there is a possibility someone has put new grease seals in the bottom of the spindles. If they put the seals in with the lips facing toward the bearings, that'll air lock the grease cavity and not let grease in. If that's the problem and you put new seals in the right way, it may be too late for grease to quiet down the noise.
If you can change wheel bearings on the front wheels of an old RWD car you can change spindle bearings. Same procedure except for the seals. Take the blades off and pull the spindle straight up out of the bearings. Knock the races out with a punch.
I've found out that a more common source of noise on those decks is the idler pulley on the deck. Another source is the mule drive pulleys. Spin each one independent of the other and listen.
