Hello to all! Gentlemen, I'll intro later. 20 year H-D mechanic here doing a favor for a friend. I'm replacing the rear rotor and need to remove the rear axle to access the rotor bolts and to replace a "drive pin". Question - The 46mm nut capturing the left side of the "splindle" , left hand thread or standard? and do you/should you replace the "special" nut? lastly, I'm big into torque values so whats the spec? THANK YOU! Respectfully, TK.
