66 Dart u joint

I run into this all the time,and some joints are tougher than others, but new joints seem to always be very snug w/the clip install. I agree with 66Dvert, that yoke looks squeezed.
I usually take the time to clean the inside of the yoke well,dress any dinks in the bore from knocking them apart, & run a flat file across the surface. I can't imagine You have a 1yr.
only joint almost nobody is aware of, it's not as hard as some think to deform/tweak the yoke ends.
