this is a dangerous situation , there is really nothing holding the shaft in place , the coupler cannot slide off the steering box because of the roll pin , the end of the shaft has the crosspin & shoes inside the coupler & there is a tiny press pin [maybe 1/8"] in the end of the coupler that holds the shoes inside the coupler that is it , so the shaft theoretically will not creep up & come out of the coupler but you are betting you life on tiny press pin so at least make SURE the pin is in place , the crimped cover barely stays on so that will not help it stay together at all .
