Wrong axles or a problem with the retainer "C" clips on the end. Not alone-others have had this problem too.

If they pull out easy then yes but if they snap-in correctly, something else is causing the problem. Check the fitment of the splines and the length of the axle when fully jacked up and off the ground. Some were too short, meaning at full distension that force against the C clip causes it to pull through.. especially while rotating....and really especially if the splines fit loosely. Also check the thrust or end play of the carrier. It moving back and forth can also play hell on the clip.

My first thought is the axel nut not having a carter pin and backing off. 🤔
