I've tried thread locking the set screw, even tried thread locking the 2 ends of the driveshaft pin to the axle - no luck. Does anybody else have this problem n how can I fix it?
You can try two things, lightly dremel the pin so the set screw can have more contact or try using heat shrink over the axle area. I've used Heat shrink in the front but never in the back so you're going have to experiment. I have experience a pin backing out before so I do dremel a small flat.
