Ice Bear Trike. PST-50. Clicking in the axle. By rogercom (Read 216 times)

My Ice Bear Trike just started making a clicking noise on the right rear axle. If I rotate the wheel or axle hub by hand. Every revolution, it clicks once. Are there bearings in the ends of the axle tubes that go bad. Behind the castle nut.It only does it once every revolution but very noticeable.

Thanks for any help.
