Wandering drive pins

[DJ's Dad]

I'm sure I read somewhere that others had suffered the drive pin that slots into the diff outdrive coming out under centrifugal load?

I want to ask what I stick them back in place with silver solder seems good to me but I don't want to temper the shaft. Is loctite sufficient?

Not experienced this with the B4 or DEX410.

Ideas appreciated - thanks Nigel.
