Has anyone else installed these on their stampede/mj truck? I'm having an issue when I tighten the wheels on the rear the hub will slide up against the axle carrier and the wheels won't really spin. I didn't use the red threadlock on the screw to tighten the hub, I'm wondering when I tighten the wheel nut if it's loosening the hub screw or if I need to try something else.

The only downside to these axles is that there isn't a hub rod the hub can clip on to. Any ideas would be greatly appreciated.
