Jon boat trailer wheel wobble.

[TyeCope122]

Hello!


I have a Jon boat trailer that I am fixing up and need to know if the bearing or Hubs need to be serviced or replaced. The hubs are going back and forth on the axle. I’m unsure what to do to fix it.I have included a video of what’s the Hubs are doing.

minimum issue could just be they are not tightened properly. Worst case would be worn bearings/ races. Neither scenario looks like they are greased properly also.
If the hubs and spindle are ok, replace the bearings/ races, pack and tighten them as required . Use new grease seals.

The play in the bearings/hub you show in the movie is very bad and unsafe.

Remove the cotter pin and tighten the nut with a wrench, while spinning the hub. Now, without moving the hub, loosen the nut and then hand tighten the nut. Now check the hub for proper movement. Hubs should turn freely without any play, if bearings and races are good.

Bearings are less than $25 each. New axles with new hubs and bearings are $125 or so, maybe less. Just match 'em up.
