if they didn't come with grease fittings, then I wouldn't bother trying to put them in. the balljoints that JD uses are meant to be permanently sealed. They don't let anything in or out, thus they should never need lube. They will eventually wear out and need to be replaced, but they require no maintenance.
truee, its not a big concern.
just curious to see if anyone has done it.
its more for the sake of cheap preventative maintenance to help em last a lil longer.
