I always run atf in the chaincase. I like lube in my chain pins when it's below zero. If you have'nt greased that bearing and have it 4 years you might as well replace it before you walk home! Track hum could be from the bearing, hitting the rail tips, track too tight, too loose, hyfax cut to long and not beveled, hyfax worn and the track nubs are hitting the front croos tube, and (or) the track needs to be adjusted to run in the center of the skid. Easy!
