Going to take a tad bit of material off around where the c-hub pin to see if that helps.
With regards to the arm and chub binding, the quality of the latest plastics is much better than what we used to deal with. It's only Every now and then you get either an arm or a c hub that's tight, like the plastic didn't set properly and it's slightly warped and binds the pin into the arm. unfortunately sounds like you have both. I've tried a few different ways to fix this over the years and if you sand the outside or ream the entire hole in the C hub it creates uneven surfaces and it will be free but will have more slop.
I've found that if you get your body reamer and lightly ream both sides of the c hub and then give the arm a very light sand just around the inside edge of the arm as pictured you can eliminate most if not all bind. I also ream the steering knuckles before I install them as I like those to be super free too.
