Quoted from CrazyLevi:
These things are cheap. I too went through the “can I buy a new wheel?” Thing with harbor freight. I was kind of annoyed until I remembered I’d got over 10 years out of a lift cart I paid $120 for.
Probably easier to just buy a new one.
Not quite 10 years out of mine, though I have thought about it since someone my hydraulic is a bit moody (guess it is due to a drain)... I was waiting for a 20-30% BOOOOOM discount
But if you have an old one with some extra wheels lying around, i'll take them
