Steering Shaft Collapse Question - 1 Plastic Pin Missing

When I modify a shaft end to convert to DD....those little plastic suckers break off and IMO....not repairable. I would imagine they were one and done / non -serviceable break off pieces to begin with.

My fix is to just put the hollow 1"" DD (bottom) portion in my arbor press to tighten up any slight toloance so there is no slop in the 2-piece shaft. If I go too far, which is hard to do, I simply force the 3/4" (top) solid DD end into it to stretch it back out. Grease it up to it does not rust and you have a nice tight fit that can still collapse ....if needed.
