Narrative:

We pushed back in ZZZ; taxied out; and flew to ZZZZ. It was raining in ZZZ; and a dry night in ZZZZ with light winds out of the east. The taxi; takeoff; flight; landing; and taxi in were all normal. A little pulling to one side on taxi in; but not unusual. After securing the aircraft and getting ready to leave; our agent in ZZZZ told me to check out one of the wheels. (Right truck; right aft wheel.) I went down to the ramp and saw one of the wheels was at an angle and looked like it was ready to come off. I called maintenance and explained the situation and an appropriate logbook entry was made. Callback conversation with reporter revealed the following information: crew was ready to leave the airplane when a passenger agent advised them to look at the right landing gear as it did not look right. Upon inspecting the right landing gear; it was noted the right aft wheel axle had separated from the right landing gear truck beam. There was nothing in the operation of the airplane to indicate the landing gear malfunction. Reporter stated landing gear was nearly at required landing gear replacement time-life cycle.
