Tried the muffler clamp method: two issues
1. 2" muffler clamps of circa 2011 do not have long enough studs to place second half on top
2. 2-1/8" u-clamp using 2" end caps produced not movement and a stripped lug bolt (ugh!)

Now it needs to come off for sure!

Chisel method: I don't find enough room behind the rotor to hit the chisel. Could you let me know which kind/size chisel you used?

Weld nut method: i don't have the welding facility (or skills)

Channel locks/vise grips: it ain't budging, not working for me.

I appreciate all of the ideas but... are there any other ideas?
