I suggest that you take lots of pics. Look in my photos. I took my T-555 all apart and took lots of pics. I took the axle apart and had to clean all the crud out of the axle. New grease. If you take it apart and any of the bearings are junk.Replace them. Go slow. It takes less time to do it right the first time than to have to do it a second time...
There are also lots of pics of my Dunecycle Flat Tracker
