i bought a used TT. when i got home. i touched the rims near the
center and 1 was warm while the rest were cool.
i jacked it up. i grabbed the tire and i could wiggle it a little bit.
found nut was not tighten correctly. could turn it to next cotter pin slot.
removed outer bearing. not much grease in there. repacked with grease.
ordering all new bearings so i can replace them myself. then i know they
are done correctly. do yourself a favor and check bearings. you do not
want a problem on the road. this could be a disaster.
plus it mite save you from buying a new axle. (cheap insurance )
