Hi,
I just read through the directions and like you, I feel they are extremely vague. As far as a puller, nothing is indicated and looking at the pictures, it doesn't appear to have the design for one.
If I recall, this will not just wiggle off. I had to use a wheel puller very some ingenuity to remove one approximately 2 years ago. I'm trying to remember what I did and can't recall what I used. Ugh! I'm getting old. LOL
By chance, do you see anywhere strong enough that would take the pressure for a puller? Also, I was able to track down the torque specs. I attached them below, and yes, the nut needs to be replaced.
Let me know.
Joe
