A wheel is an endless arch with stress in one quadrant transferred to the rest of the wheel. except when you've got a pinned joint and it's at a 90° to the impact that caused some momentary distortion of the arch. When that distortion occured, it looks to me that the two pins holding your wheel together, bent.
You could create another impact and try to bend the pins back, or you could do the reasonable thing and realize that your wheel is probably not long for this world. Every time you roll on that joint it's going to flex those pins and the holes they are in until it fails.
