I've got an issue with my banjo's neck--it's tilted, so that on the high D side of the neck, it's closer to the strings, and on the low side, it's farther away from the strings. Or, using the tension hoop as reference, the neck sticks up noticeably where it meets the hoop on the end with the high D string, while the side with the 5th string peg doesn't extend above the hoop.
I'd say the neck looks pretty straight, not warped or excessively bowed, and it's totally playable, but it does mean that I have less space for my first string, so my fingers will slip off when I'm fretting it and hammer-ons don't always sound great.
The banjo is a 1970's Japanese-made Aria with a single coordinator rod--hopefully the pictures tell the story pretty well.
Does anybody have any advice on fixing this issue? I'm hesitant to go crazy with taking the neck off, but it seems like pulling it off and resetting it would be the way to go.
Thanks! Any help is appreciated :)

There is a good possibility that you can just tune down the strings, loosen the coordinator rod and additional nut, and turn the heel by hand so that the fingerboard is level with the tension hoop. I have had to do this same operation in the past and it is fast and simple. It's quite likely that there is enough play in the rod and extra nut inside the pot that you can put this right without straining anything.
Seems like there should be a washer over the coordinator rod in the first photo.
Very simple fix, loosen the lower co-rod and the top nut and gently twist the neck to it's right position. I would also add that there should be a washer between the co-rod and the rim, this has already been mentioned by Banner Blue. Tighten both the co-rod and the top inside nut, however do not over tighten either of them, just a nice snug fit.
Best case: loosen the co-rod and twist the neck straight and re-tighten
Worst case: relocate the hanger bolt in the heel
