My guess is that you're running on pavement? When turning, physics dictate that the outer wheel must travel farther than the inner wheel. Since you locked your diff it's now forcing both axles to turn at the same rate. The axle is popping out because something has to give and it's now the weak point.
You may find that the inner bearing on your outer hub is bad, and is allowing the axle to push outward far enough to pop free but if not you may need to free up the diff to allow turning.

Any particular reason that you locked your diffs? I doubt you'll be able to solve that if you keep it locked, as said above there has to be something that will give. The Traxxas drive shafts are very strong, I use them on both of my crawlers where they get a ton of torque working through binding wheels. Once you pop one the plastic part is probably stretched or even broken so you'll need to replace that part most likely.

Sure you're not just missing the grub screw? You had to take it out to lock the diff...it goes through the outdrive and it holds the outdrive to the diff. If it's there, there's no way for the axle to come off. It's a little post with threads and it's maybe a half inch long or so at the most.

I had a Rustler with a locked diff and I never had a problem...and we beat the hell out of it with a 7-cell battery and a brushless motor.
