I bought a new, almost identical 5 inch bolt this morning. I was able to get the assembly square, but in order to get all bearings touching in the back I had to really tighten that 5on bolt. Enough so that it warps the entire center assembly and it jams the lead screw. I will try another section of conduit from another store but I haven’t had any problems with the reast of the build.
When I have that 5 inch bolt loose, in the back only 2 bearings are making contact with the conduit and the third has a 1mm or so gap.
Edit: added 2 more pictures showing the gap
