Drive axle

[Dxb430]

Hi guys, been running a hotbodies for a few months now and broke the aluminium drive shafts within a couple of weeks. I have replaced them with the harder steel drive shaft but im having problems with the universal cross spider part no 75188a. The grub screw to secure the pin doesn't hold it properly, i have used lock tight super glue for the grub screw but nothin holds it the pin keeps coming loose. It only happens on my front left drive shaft.
Is there somethink that i should look for that could be causing excess vibrations to loosen the screw because i have even replaced the universal cross spider, pin and screw but still get the same problem?

Any help would be greatly appreciated because i don't understand why i only happens to the one side!

if your using a spool the left side maybe warn out and causing it to vibrate
