should I add grease zerks to the front sway bar supports?

[grant mills]

I am about to reassemble the front sway bar after having the coil springs replaced. All the supports for the bushings have a 1/4" in hole (un-threaded). Would it be wise to add zerk grease fittings to these holes? My alternative is to occasionally spray some lithium grease around the sides of the bushings. (the bushings are rubber) If I do put grease fittings on...should I drill a hole through the rubber down to the bar or just grease around the inside of the supports?
