A used worn out locknut will come loose though, and why are you so against the ca'ing when the truck is fastest with full time 4wd. No one i have met or talked to thought the clicker was even a tuning option for them....more of a burden.

I sorta wish that ae would come out with a clicker delete front pulley and top shaft. It would take weight away high up on the truck, which is never a bad thing
