I bought my Trinity Freedom last year in October and have used it for quite a few jobs, both commercial and residential. I noticed the bearing was starting to sound dry and was getting rougher. When I had a bike shop I used to drill tiny holes in the headcups, pedals and hubs on mountain bikes and purge them with a needle nose grease gun. Why Not? I said to myself about the Trinity bearing, so I got out a #30 drill bit, chucked it up and drilled through the outer edge of the bottom seal. I took maybe 30 seconds. Then I got out my needle point grease gun and forced grease into the bearing while turning the bearing and driveplate slowly. I mcut a hubcap out of neopreme foam rubber that it just oversize to be a pressure fit over the hub….to keep less moisture getting to the bearing, and preventing surplus grease from leaking onto the carpet. It works great. The bearing spins better and the motor overheating problem I had experienced on some carpets is all but gone​
