With the wheel off I grab the disk top and bottom and give it a wiggle. If I tighten the caster nut to where it just makes contact the wiggle stops. But then I have to loosen the nut a little to get the cotter pin on, and I'm back where I started.
Thoughts?
Rather than back off at the just touching point, why not tighten it a little more to the next slot in the nut and see if it will still rotate freely and without any graunchy noises?
