I’m more wondering if the hubs or maybe just the spindles are now worn out of from the KPI being off and that’s what’s thrashing the bearings? I just know when I was looking at build a T bucket using that same year axle, there were loads of reports of both KPI and Ackerman causing hubs to fail with certain kits. I’m a little curious too if the 37 spindles aren’t up to the task of the speeds and heat of modern traveling speeds.
