Trailer wheel bearings

[oteps]

I have an extra set, seal and cotter pin in a Tupperware bin I take along incase. Had one blow up once and didn't have any parts. Ran all over to find stuff.
My friend got a spare set and used his vacuum sealer on them. I would be afraid of greasing up sealer and wife finding out. But he said it worked. Sealed up a set for his dad and uncle too.
