Dave,
Correct on everything. :bigok:
You need to remove the previous notch (notch or stake) to remove the center hub nut, then you must chisel another one to lock it back in place during re-install.
Autozone is always good with renting tools for free. Leave the required deposit and once returned you get your deposit back, therefore...FREE. :naughty:
I paid over $90 for my own s#*t and I'm not even a pro mechanic. :dunno: , I guess I just love having my own tools when I need it, and besides the nearest Autozone is a good 20 minutes drive anyway.
Axle grease will do fine. :goodjob:
GOOD LUCK and fill me in! :blue:
