Replace the bearings (use 11 brand new loose 1/4" balls per side, irrespective of whether you now have caged bearings) while you are overhauling the BB, and inspect the spindle and the cups for damage. Mark the spindle so that when you reassemble the crankset you can move the crank arms to a new position relative to the spindle (four orientations are possible; it is best not to use the same one every time).
