This is not a do it yourself project unless you have an Ingersoll Rand pneumatic air hammer and 120# of air. To remove the front axle nut (to gain acess to the rotor, to install magnetic bolt and drill hole in rotor guard for sensor installation) you need to overcome 190# of factory set axle nut torque. Good luck with that without an air wrench handy its **** near impossible. If you do get it off the magnetic rotor plate bolt they supply is as brittle as glass, anything over 10# of torque will rip the head off, which by the way is not a recessed bolt like the factory rotor plate bolts are. This leaves very little clearance between the bolt and brake caliper so it is real prone to break off from mud, sticks and debris. 2 out of 5 stars. Easy install my ***!
