|I just got a set of skates off ebay and I asked about how I tell if certain things are OK, etc.
For bent axels, I was told to do this:
"an easy way to spot check an axle is to mount up a good set of wheels....and place the skate on a surface you know to be flat. Look to see that the wheels touch the surface evenly, that the end opposite the truck isn't lifted slightly. Axles will generally bend up, not down. This won't work with old, worn wheels, as they'll wear more on the outsides."
So looks like your skates have a bent axel? Well, I have one on these skates too lol.
