The bearings are cup-shaaped, I used a dremel to grind off the centre 3/4 of the end of the bearing cap each side. Then I used it to carefully grind off the peened over metal that retains the bearings. Note, there is a rubber seal on the pin between the bering cap and the centre piece, each side. This will be toast by now. Use a point to dig it out first, so the rubber does not damp the hammer blows.
