Installed the new Gille's Axle Nut. Nice thing for $85.

Bow weighed more than the nut itself, but it also has the hex wrench too. The hex setscrew actually moves a nylon threaded piece up against the threads of the axle and not all the way through it out the backside like most setscrew things.
Pulled the rear wheel out and lubed the two bushings with wheel bearing grease while doing it. Axle took some of the same wheel bearing grease too. Bushings were almost dry which would explain the squeak some have when hot.
Someone told me to smack the rear tire with a 8-10 pound dead blow hammer while snugging the thing up to keep it from doing some side-to-side shifts. I also used a cheap $2 squeeze clamp on the right-axle block to pull it forward in the swing arm while snugging (hint: a screwdriver wedged between the upper chain and large sprocket helps to keep some slack in the chain while tightening the axle nut).
I also found some little chain aligner tool at Harbor Freight on their specials table for only $1.98 that sells for about $30 in Cycle Gear. Might want to see if your local HF has one on their discount or closeout table. Some clamp-on with a rod to point towards the front and align the chain. Worked well enough and maybe a bit more accurate than their reference guides on the swing arm. I wish the long aligning rod was a bit longer by 3-4 inches or so. Easily fixed if I go to the hardware store and buy a longer piece.
