The g-force locknut won't tighten completely up on two different Raptor's....you can turn it by hand and you feel it snug up, but if you keep turning it just loosens a little then snugs up, etc. etc. etc. It doesn't have a "set screw" like stock locknut....it has and allen head bolt that runs perpendicular to the axle in the lock nut. My main concern was the fact that it doesn't tighten to a positive stop.....didn't know if it was normal on these g-force axles............thanks
