I just got a new set of these from ToadzRC on eBay and I'm having a heck of a time trying to get them to work. First of all, the set I received doesn't look anything like the ones on the STRC site- no set screw on the hex and the drive pins are much shorter (looks like these, but in gray) I guess a new version. Anyways, since I'm assuming the longer hexes go on the front, I test fitted them and once I get the flanged drive pin snugged down they don't spin freely at all- lots of binding. I installed 2 new bearings and a new axle and the same thing. What the heck am I doing wrong?
