This is too easy to install
Absolutely great system that is so simple to install. The instructions were clear and installation was very simple. Yes, you need a castle nut wrench, but you don't need a torque wrench. I used one and found it was almost in the way. You do not need to torque this to 40 foot pounds. You tighten it 2 clicks past fully seated.
