The wheels of the garbage bin used for 22 years fell off. I tried to hammer them in from the outside of the bin but in vain.

So I sawed a fallen tree branch into two logs:

They are both longer than the height of the garbage bin and from the inside of the garbage bin I put one end of of a log against the places where the axle of wheels sits:

Then let the garbage bin and the log stand up together, use the hammer to force the axle of wheels in, repeat for the other location:

This is the mark on the log from being hammered:

Done.
