Dana 300 shift rail caps popping off

Just finished making my Dana 300 shifters and running through the gears it keeps kicking the shift rail caps off the back. Just installed the 300 so I don't know if it had a problem or is this common? It's flipped so it dumps oil when they pop off. I don't want one of these coming off on the trail.

I haven't seen this with the 300. Maybe because it's flipped?

Same thing happening to me. Haven't been out to the garage to see how to fix it yet. Still in build mode on the Jeep.

Doesn't sound like a common problem with these flipped but I don't trust mine now so I'm going make something to keep the caps from moving.

Had this happen once at the end of a snow run, dumbest reason I have ditched my rig in a parking lot to snag tow rig and trailer. Buy new end caps and make sure they fit snug. I also put alittle gasket maker on it too to add a glue effect and it has not popped off again. But I do carry a spare cap now as they seem difficult to buy when in the middle of no where.

I have a D300 flipped in my Willys. I've hypothesized that the issue is due to hydraulic pressure when the fluid drains into them and then shifting forces the shift rod into that fluid-filled cavity. Here is my quick and dirty solution...

IIRC, there is a small groove machined in the end of the shaft to allow trapped oil to flow out of the cap while shifting. I suppose it could be plugged with debris or excess sealant from the cap. Also, the groove could be opened up with a mill for more oil flow before the shafts are assembled.
