From the looks of it, it was changed once before, Hoover never used "Pop rivets" to hold on their wheels, they used solid rivets, being that these are Pop rivets, it is easy, just drill out the center of the rivet with a 1/8 drill bit until the head comes off, get a new wheel, an Electrolux front swivel caster is the same wheel, obtain a Pop rivet gun and just rivet it back on, less than a 5 minute repair, nothing has to be taken apart, very easy.
