My tractor is a '51 8N, 12 volt, side mount.
I heard a "clunk" in the right rear wheel. When I pushed against the top of the tire I could feel "play". I've taken the wheel off and pulled the axle out. There was no oil on the brake drum, and no oil on the outside of the wheel. The bearing looks good - no missing rollers and it doesn't make noise when I spin it. Should I replace it anyway?
