That is definitely a LEFT handed thread!Thanks for all the great replies. Braeden P., thank you for sharing the pics of your spindle. Very interesting. Mine appears to be different as my slot looks like a nut with a right handed thread. There is also an internal thread on the wheel adapter that fits a wheel puller, I believe, once the nut is removed. I’m learning all this as I go.

The axle is left hand and shell look to be right.Thanks for all the great replies. Braeden P., thank you for sharing the pics of your spindle. Very interesting.

The pic shows the internal thread of the outer case being right handed. Any idea what that's for? Agreed that the inner set of threads are left handed.
Got an impact gun? Find a socket that fits inside and grind it so you get two protrusions that nearly fit the slots. Make up a soft ali pin spanner to hold the spindle still and have at it. It may sound brutal, but you're not putting any bending forces on anything and percussive persuasion has the best chance of anything getting that to budge.
Good luck!
